Every time a construction project is started, one has to calculate the financial costs, regardless of whether the house is being built with one’s own hands, with the help of neighbors, or by professional builders. Significant differences will be in the timing, quality of work performed, but most importantly - in the price of the entire event.
You can reduce risks and get high-quality results by engaging a certified professional contractor. The preliminary cost of building a house can be calculated using an online construction calculator.
Calculation methods for construction work
Calculations can be made in three ways:
- Measurements based on the design area.
- Calculations based on built-up area.
- Determination based on construction volumes.
The first two methods result in an inflated estimate. It includes additional costs for the expected overconsumption of material and an acceptable increase in its cost. The possibility of additional unforeseen costs is taken into account.
The third approach (calculation based on real volumes) is more accurate and objective. He takes into account the work that will be directly carried out. The volume of completion for each construction segment is calculated. Therefore, at the stage of drawing up estimates, the customer has the opportunity, without disturbing the project, to make his wishes for individual structures (for example, for floors, roofing). Deviations from the total cost are possible within 15%.
According to the latter principle, unlike many other resources, a unique mathematical calculator for calculating the construction of a house from the website works.
Calculation algorithms for an online calculator for building a house
The calculation is based on simple mathematics. First, to determine the volume, you need to set the width, length and height (thickness) of a certain structure.
Secondly, take into account building codes and rules that apply to the specific structures chosen for the project.
Thirdly, the current price of the materials used, the tools used, the equipment used, and the labor of specialists is taken into account. It is important that our prices for building materials are stable and there are no sudden jumps. This is possible thanks to the presence of our own warehouse store with materials.
Fourthly, the calculations are based on existing and tested drawings. Therefore, when designing a house on our construction calculator you get a result that is associated with actually implemented projects. The constant practice of contracting work allows us to take into account all, even small, current costs. That is why construction cost calculations using this online calculator are more accurate than those obtained from similar services.
Fifthly, the reliability of the result is ensured by adding up separate calculations for each construction segment:
- laying the foundation;
- construction of walls and ceilings;
- roofing with the installation of a chimney;
- installation of stairs, windows, doors;
- façade design.
In addition, you can use our calculator to calculate the cost of building or repairing individual structures of your home.
Features of the formation of the price of work for different elements of the structure
Foundation
Before starting calculations, you need to decide on the type of its design. The settings of our computer provide the following foundation options:
- strip on stilts;
- tiled monolith;
- monolith with a base;
- with a ground floor.
The design is selected taking into account the mass of the designed structure and the geological features of the soil at the site.
Next, for calculations, you need to indicate the dimensions of the desired building (width, length) and the thickness of the foundation. We get three numbers: the price of the work, the cost of materials, the final cost. This result will appear at every stage.
The scheme is similar. We choose which walls we will build and the height of the floor. We suggest paying attention to:
- cellular concrete blocks;
- walls made of ceramic bricks;
- porous ceramic blocks.
It is worth knowing that the calculator will calculate the construction of a house from blocks a little more expensive than in the case brickwork. But we advise you to initially choose material based on characteristics, not price.
Floors
The construction of floors is of particular interest due to its ability to combine various options. The online construction calculator offers you to select floors for the basement and floor separately. Also note the difference in design:
- wooden or glued beams;
- concrete plates or monolith.
In your choice, it is important to proceed from general requirements to the structure under construction and financial capabilities. With proper selection of floors, you can even save money. For example, it is better to use concrete between the basement and the first floor. The house will be better protected from moisture coming from below, and the floors will withstand heavy weight. At the core attic floor you can use wood, less durable concrete, but cheaper. This will also improve thermal insulation.
If you insure yourself as much as possible in terms of fire safety, it is better to contact concrete partitions. However, it is important to consider the possibilities load-bearing structures(foundation, walls) in terms of withstanding significant loads.
Roof and chimney
The difference in their range is only in price and aesthetics. The elements fully perform their functions, regardless of price. pay attention to the following types tiles:
- natural;
- composite;
- bitumen (soft);
- metal.
The latter option is characterized by the greatest prevalence in modern construction. The chimney pipe can be chosen from brick, ceramics or stainless steel.
Ladder
The staircase is one of the elements of the house that cannot be defined by volume. An online calculator for calculating the construction of a house determines the price of stairs based on the material of manufacture and the number of floors. They can be wooden, metal, monolithic (made of reinforced concrete).
Windows, doors
Unique feature The website's house construction calculator takes into account the areas allocated for window and door openings. When you indicate the number of windows and doors, the final price of building a house according to the calculator will be lower due to the reduction in the calculated volumes of materials for the walls.
Exterior finishing needed not only for the exterior, but also for the heat and sound insulation of the building. An online calculator for determining the cost of building a house shows options for facade design using:
- clinker tiles;
- facing bricks;
- technologies " wet facade»;
- ordinary plaster.
The latter option is cheaper, but the plaster must be applied to walls whose thickness provides thermal protection.
Using a website construction calculator will help you not only imagine the cost of work, but also develop a preliminary detailed project houses made of aerated concrete. The accuracy of the calculations is guaranteed by a combination of theoretical calculations with real experience in carrying out many construction projects.
To give the structure stability and strength, it is necessary to install over the foundation at the construction stage. In the future, it will take on most of the load of the future structure (pressure from floors, walls, roofs, etc.). As a rule, the base is made of brick. The walls of the basement experience serious loads, so it is customary to use solid red brick for its construction.
Markings that can be used are M200 and higher strength factors. This brick has more weight than its traditional counterparts, but in this case it's justified. It is also important to correctly calculate the bricks for the plinth so that you definitely have enough material and do not have to overpay.
It is better to take time in advance to correctly calculate the number and weight of bricks.
Brick M200.
It is important to remember that the performance characteristics of a product with similar markings, but from different factories, often do not match, and this negatively affects the strength and reliability of the entire building and the base in particular. In addition, material from different batches differs slightly in color, which can spoil the entire exterior of the structure.
Calculation method based on plinth area
In accordance with GOST, the dimensions of red brick are as follows: 250x120x65 mm. All its sides have their own name: spoon, bed and poke, respectively. The amount of material is calculated using several methods. The initial data in the first method is the area of the plinth along with the area of one of the sides of the brick. To calculate, you need to know for sure general dimensions object.
Standard sizes.
As an example, let's take a house whose base area is 5x4 square meters. m. Of course, the size of the house can be any, but we give examples of the most convenient ones to calculate, so that you don’t get too confused in the calculations.
The standard height of the plinth is 1 meter. The length of the walls of the building is 18 m (5+5+4+4 m). You can calculate the amount of building material in meters, which will be more convenient.
Names of the parties.
The most simple masonry it is made so that its thickness is a multiple of half the length of the brick. The width of a standard brick is 0.12 m, which fully corresponds to the width of such masonry.
When laying a masonry of one brick, its thickness will be 0.25 m, and if one and a half - 0.38 m, etc.
Main types of masonry.
Mortar joint.
Based on the above, if the area of the basement base is 18 sq. m (18x1 sq. m), when multiplying the resulting base base by this value, the quantity required for work is obtained - 1107.54 pcs. (1108 after rounding to big side). This amount of building material will have a very large weight, so it will be very difficult to deliver it yourself.
By the way, the same amount of material for the basement extension is obtained by dividing the area of the entire surface of the base by the previously obtained spoon area, namely 18/0.01625 sq. m.
If necessary, masonry of one brick or wider can be used. Accordingly, the wall thickness will be 0.25 m or more. Despite this, we consider the basic value only for half-brick masonry. Simply then (when laying in one) we multiply this value by two, when laying one and a half - by three, in two - by four. In other words, how many times the half fits in the thickness of the masonry, this is the multiplier of the base number.
Calculation method using volume
To calculate the required amount of material, you can use a volume measure.
V (basement) = (5+5+4+4) m x 1 m x 0.12 m = 2.16 cubic meters, V (brick) = 0.25x0.12x0.065 = 0.00195 cubic meters. Everything seems very simple, and it really is.
When dividing the volume of the base by the volume of the brick, we get the required amount of material: 2.16/0.00195=1108 pieces after rounding up. Therefore, for the entire base we will need 1108 bricks, excluding mortar joints and breakage. As a result, we see that after two calculations there is no difference between the two obtained values!
Using the method of counting quantities using volume is also relevant and no less accurate in terms of the final value. True, sometimes it is difficult to compare the sizes of the base and individual bricks.
Quick calculation table
These two methods of calculating bricks for building a basement are, in fact, approximate. There is no need to talk about ideal accuracy here, because the bricks will have to be connected to each other cement mortar, provided that the thickness of the connecting seam often exceeds even 10 mm. The seams, in turn, are located between the rows of masonry (horizontal and vertical seams, respectively).
When calculating quantities, size is taken into account, but weight is not taken into account. And when delivering building materials, weight is a very important parameter.
The following should be remembered:
- When calculating the amount of material, it would be correct to take into account a certain thickness of the connecting seams. However, in practice it is very difficult to calculate in advance the exact thickness of these seams.
- Also in the base there are almost always ventilation windows, the area of which must be subtracted from the resulting value.
- In addition, during transportation, delivery and unloading, debris will certainly form. Often it reaches 5-10% of total number material. This also needs to be taken into account when making calculations.
The approximate amount of red brick per basement extension can also be calculated using the table of average values given below:
| Unit | Brick size* | Excluding growth seams, pcs. | Taking into account the growth seams, pcs.** |
|---|---|---|---|
| 1 m³ of masonry | single | 512 | 394 |
| one and a half | 378 | 302 | |
| double | 242 | 200 | |
| 1 m² of masonry with 0.5 bricks (masonry thickness 12 cm) | single | 61 | 51 |
| one and a half | 45 | 39 | |
| double | 30 | 26 | |
| 1 m² of masonry in 1 brick (masonry thickness 25 cm) | single | 128 | 102 |
| one and a half | 95 | 78 | |
| double | 60 | 52 | |
| 1 m² of masonry with 1.5 bricks (masonry thickness 38 cm) | single | 189 | 153 |
| one and a half | 140 | 117 | |
| double | 90 | 78 | |
| 1 m² of masonry in 2 bricks (masonry thickness 51 cm) | single | 256 | 204 |
| one and a half | 190 | 156 | |
| double | 120 | 104 | |
| 1 m² of masonry with 2.5 bricks (masonry thickness 64 cm) | single | 317 | 255 |
| one and a half | 235 | 195 | |
| double | 150 | 130 |
The implementation of activities for the construction of a private house is inextricably linked with the implementation of calculations. They allow you to accurately determine the need for building materials for the basement of a building, main walls or foundation. Let's consider the basic methods of performing calculations various types. Knowing how to correctly calculate the brick for the plinth, depending on the chosen masonry method, you can promptly purchase the building materials necessary for construction, which will significantly speed up the completion construction work.
Basement brick - sizes, types, terminology
When planning the construction of the basement foundation of the building, you should decide what building material will be used for the masonry. Professional builders for these purposes it is recommended to use solid brick, which has the following advantages:
- increased resistance to mechanical loads;
- resistance to influence high humidity.
Let's figure out what types of bricks exist:
- ceramic, for the production of which clay and quartz sand. The manufacturing technology involves high-temperature annealing, which increases the strength properties and moisture resistance of ordinary clay bricks;
- silicate, which is easily distinguished by white color. Produced by autoclave processing in chambers where high humidity and temperature are maintained. Strongly absorbs moisture and is not used for basements and bases;
- fireproof, which maintains integrity when heated to 1.5 thousand degrees Celsius. Refractory brick has a yellowish tint and is made from fireclay. The material is used in the construction of furnaces and retains its structure during repeated heating and subsequent cooling.
Of the indicated types of bricks for masonry construction, it is better to use ceramic ones marked M250, produced by high-temperature firing of clay. Such building brick withstands a force of 250 kg per square centimeter of area and has a standard size - 25x12x6.5 cm. Externally, the product is cuboid, each side of which has its own name:
- bed. This is the largest part in area, having dimensions of 25x12 cm;
- spoon part. Spoon – larger end with a size of 25x6.5 cm;
- butt plane. The butt is a reduced end with dimensions of 6.5x12 cm.
Hyper-pressed plinth solid single-face brick Dimensions different types brick products differ and are:
- for a single brick – 25x12x6.5 cm;
- for one and a half - 25x12x8.8 cm;
- for double brick block– 25x12x13.8 cm.
Knowing the sizes of the blocks used for plinth masonry, it is easy to independently calculate the number of bricks per plinth.
Getting ready to calculate the amount of bricks for the plinth - preparatory work
Before calculating the brick for the plinth, you should decide on its design. It can be different:
- protruding beyond the contour of the wall;
- corresponding to the width of the wall;
- recessed 50–70 mm relative to the wall of the building.
Construction of a brick plinth - thickness of the base. In most cases, the width can be 0.5, 1, 1.5, 2 or 2.5 bricks;
- height basement wall. The height dimension is determined according to the requirements of the project, taking into account climatic factors and must exceed 50 cm;
- perimeter of the basement base. It is calculated by adding twice the length and width of the building being erected;
- dimensions of the brick used to build the base. From what it has plinth brick dimensions, depends on the amount of building material;
- dimensions and number of openings. If there are openings located in the basement of the building, then the need for building materials for masonry is reduced;
- thickness of the mortar joint. The correct calculation of the amount of material depends on taking into account mortar joints;
- type of masonry used. The calculation of the brick for the plinth differs, depending on the characteristics of the brickwork.
Using the necessary information, you can perform calculations using various methods:
- using an online calculator or programs located on specialized websites;
- manually when independently performing the necessary calculations using a conventional calculator.
Let's take a closer look at the methodology self-execution calculations.
How to calculate the number of bricks per plinth based on the volume of masonry
Knowing the volume of brickwork, it is easy to calculate how many bricks are needed for the base. To do this, the volume of the basement wall is calculated, and the resulting value is divided by the volume of one brick block. Having correctly performed the calculations, the result will be the amount of building material that will be required to build the basement base. Let us analyze the algorithm for performing calculations on specific example.
Number of bricks per plinth by volume of masonry Initial data for performing calculations:
- dimensions of the building's basement are 5x6 m;
- height of the base base – 0.6 m;
- wall thickness in the basement part – 0.25 m;
- size of the connecting seam – 10 mm;
- type of masonry performed - one brick;
- dimensions of the building material used – 0.25x0.12x0.065 m.
Perform the calculation following the given sequence of calculations:
- Determine the perimeter of the base by doubling the sum of the sides - 2x(5+6)=22 m.
- Calculate the volume of the masonry by multiplying the perimeter by its thickness and height - 22x0.25x0.6 = 3.3 m 3.
- Calculate the volume of the brick block by multiplying the dimensions - 0.25x0.12x0.065=0.00195 m3.
- Determine the need for material by dividing the total volume of masonry by the volume of bricks used - 3.3: 0.00195 = 1692 bricks.
The above calculation algorithm does not take into account the thickness of the seam, the size of which slightly affects the amount of building materials required. If openings are supposed to be made in the basement of the building, then their volume must be subtracted from the volume of the masonry. By repeating the simplified calculations, it is easy to determine the need for brick blocks.
Calculation of bricks per plinth by volume How to count bricks for a plinth based on the size of the basement of the building
Using the initial data given in the previous section, we will consider an alternative calculation procedure that takes into account the dimensions of the base base. Let's compare the result obtained with the previously determined need for material and evaluate the accuracy of the calculations.
The calculation algorithm involves determining the amount of building material at one level of brickwork with the subsequent calculation of the total requirement. Perform calculations in the specified sequence:
- Calculate the total length of the basement of the future building by adding the dimensions 5+6+5+6=22 m.
- Determine the number of brick blocks in one row by dividing the result by the length of the end part (for masonry made in one brick) - 22: 0.12 = 183 pieces.
- Calculate the number of horizontal rows by dividing the height of the base by the thickness of a standard brick block - 0.6:0.065 = 9.2 rows.
- Determine the need for material by multiplying the number of blocks in a row by the number of rows rounded to 9 - 183x9 = 1647 bricks.
The resulting calculation result for the wall area (1647) differs slightly from the material requirement determined by the volumetric method (1692). In both cases, the thickness of the binder solution, equal to 1 cm, was not taken into account. If it is necessary to obtain more exact values it is necessary to take into account the thickness of the seam taking into account the configuration of the masonry.
Calculation of stairs - general information
At the design stage, after clarifying the dimensions of the plinth and studying the layout interior spaces, perform the calculation staircase structures. Before starting construction of the plinth, you should evaluate how they will be located internal stairs and whether it will be necessary to adjust the size and shape of the basement of the building in the project.
Calculation of staircase structures At the design stage, the following points are taken into account:
- dimensions and area of the interior;
- height difference between the floor and ceiling;
- features of the internal layout;
- location coordinates doorways;
- location internal partitions.
Important factors when designing and linking staircase structures are:
- tilt angle flight of stairs. Optimal value For safe use and comfortable operation is 28–34 degrees;
- size of the step support. The indicated value is 25–30 cm, which ensures ease of movement;
- height difference between adjacent steps. Requirements state standard provide for the value of this parameter to be 18–20 cm;
- width of the stairs. This characteristic is 0.9–1.1 m, which ensures comfortable operation.
When deciding on the design of a staircase, first of all you need to pay attention to safety, reliability and an increased margin of safety.
Conclusion
It is not difficult to independently calculate the amount of bricks per plinth if you know the technique. It is important to take the development of the project seriously and choose the right type of brick blocks used. It is necessary to evaluate a complex of factors, including the dimensions of the base part, the thickness of the seams, the type of masonry, and the dimensions of the openings. Calculations should also be made to tie the building partitions and staircase structures to the basement base. Proper execution calculations will allow you to purchase in a timely manner required amount building materials and reduce the duration of construction activities.
Building brick is one of the most popular building materials in our country for construction. residential buildings and other buildings for various purposes. Before starting any construction brick building it is necessary to purchase the required quantity of bricks, for which a preliminary calculation must be made. Correctly carried out calculations will allow you to avoid unnecessary costs for the purchase of excess building materials and avoid problems with their shortage during construction.
Before you start making calculations, you need to determine:
- type of brick used;
- method of laying bricks, depending on required thickness house walls;
- total area walls of the house (external and internal);
- the total area of all window and door openings in all walls of the house.
At the beginning of work, it is necessary to calculate the load on the foundation.
Main types of bricks and laying methods
Standard brick produced today various manufacturers, has the same dimensions in length and width (25x12cm) and differs in thickness by:
- Single (0.65cm).
- One and a half (0.88 cm).
- Double (1.38cm).
Walls made of single bricks look the most aesthetically pleasing. However, the use of one-and-a-half or double-thick bricks can greatly speed up and simplify the construction process. At the same time, the consumption of masonry mortar used is also significantly saved.
The thickness of the walls of the house depends on the methods of laying bricks. They can be:
- half a brick (wall thickness 12cm);
- 1 brick (wall thickness 25cm);
- 1.5 bricks (wall thickness 38cm);
- 2 bricks (wall thickness 51cm);
- 2.5 bricks (wall thickness 64cm);
In the Russian climate, the most optimal wall thickness is 2 or 2.5 bricks.

Calculation of the required amount of bricks
Calculation of the amount of brick can be carried out in two main ways:
- Does not take into account the thickness of the mortar joint.
- Taking into account the thickness of the seam, which is usually from 5 to 10mm.
It should be borne in mind that when using the first method, there may be an excess of building materials by 25-30%. The second method is more economical, but it is necessary to add 10-15% to the calculated value to take into account possible brick breakage during construction.
For clarity, let’s carry out the calculation using a specific example: It is necessary to build a one-story brick house 8 by 10m, walls 3m high and without internal brick walls. There is one opening in the external walls for front door 1 by 2m and three openings for windows 1.2 by 1.5m. The thickness of the walls is two bricks from a standard single brick with a joint thickness of 5mm.
The calculation procedure for the first method will be as follows:
- We determine the perimeter of the external walls: (8+10)*2=36m.
- We determine the total area of the walls of the house: 36*3=108 sq.m.
- Determine the total area of the door and window openings: (1*2)+(1.2*1.5)*3=7.4 sq.m.
- We calculate the area of the brickwork of the walls: 108-7.4 = 100.6 sq.m.
- Determine the number of bricks in one square meter, for which we calculate the end area of one brick: 0.12*0.065=0.0078 and divide this value by one: 1/0.0078=128, after which we multiply by two (since the masonry will be 2 bricks). We get 128*2=256 bricks per 1 sq.m.
- We calculate the required number of bricks for building a house by multiplying the total area of the walls excluding openings by the number of bricks per 1 sq.m: 100.6*56=25753.6.
Thus, 25,754 bricks will be needed to build the walls of the house.
Carrying out the calculation using the second method, to determine the amount of brick in 1 sq.m. we add to standard sizes 5mm bricks (joint thickness): (0.12+0.005)*(0.065+0.005)=0.00875. Accordingly, the amount of brick in 1 sq.m will be: 1/0.00875*2=229 bricks. Multiplying this number by the total area of the masonry we get: 229*100.6=23037.4. Let's add to this value about 1500-2000 bricks per battle and we get the amount of bricks needed to build a house: approximately 24,500-25,000 bricks.
From the above example it can be seen that the second calculation method is more economical.
The calculation for other wall thicknesses is carried out similarly, taking into account the appropriate corrections. If you need calculate the number of foam blocks per house - see this article.

The construction of various structures using brickwork requires determining the exact amount of material to complete the work.
To carry out such calculations, special online calculators are used, widely available on the Internet, on sites engaged in the trade of building materials. When carrying out construction work, it is necessary to strictly follow the norms and rules to ensure the further safe and long-term operation of the objects being built, therefore the parameters of the brickwork are calculated based on the purpose of the structure and environmental conditions.
In addition, bricks from different manufacturers may vary slightly in size and in their properties, which makes it difficult to quickly select the required amount of materials for construction.
The calculator for calculating bricks allows you not only to make calculations for the construction of ordinary walls, but also to make adjustments to the estimate according to the type of masonry (from 0.5 to 2.5 bricks with dressing), the size of the object being built, the brick manufacturer and the type of mortar used. The calculations take into account the implementation of various openings for installing windows and doors with full consideration of their future length and width.
The calculator interface is very clear and does not require additional calculations. It is enough to enter the basic geometric parameters future construction to start calculations automatically. As a result, the consumer receives accurate data on the required number of bricks in pieces, the volume of brickwork in cubic meters, as well as the consumption of mortar during operation.

Features of brick consumption on the wall
When we're talking about Regarding brick construction, it is necessary to take into account not only the size of the blocks themselves, as well as the total area and thickness of the walls being built, but also the features of the masonry. The following parameters play a role:
- masonry width (from 0.5 to 2.5 bricks);
- thickness of the mortar joint between the blocks (from 0.5 mm);
- the number and location of door and window openings in the room.
It is worth taking into account the fact that even when purchasing bricks of a strictly “reference” size of 250x120x65 mm, you cannot be sure that the mortar joint between all blocks will be the same. Firstly, each batch of building materials may contain defects. Secondly, some bricks may be damaged during transportation. One way or another, the difference in size will have to be compensated by the thickness of the mortar joint. As a result, the pre-calculated amount building material will be significantly different from what will happen in practice.
This picture can be avoided, firstly, by taking into account in advance the percentage of possible brick defects (5-8%; in some online calculators this parameter is enabled by default). Secondly, everything made using special tools To be on the safe side, the calculations should be duplicated independently, guided by the algorithm proposed below.
Calculation of the number of bricks per wall - table!
- Width of external and interior walls buildings will differ significantly. The difference between load-bearing walls and simple partitions will be no less noticeable.
- The total area of the building's door and window openings will not be taken into account in the calculations.
For a better understanding of the principles, this is enough complex calculation brick, let's look at the calculations using a specific example. Let's assume that the object we are planning has the following characteristics:
- It is planned to lay out the internal load-bearing walls with a thickness of 1.5 one-and-a-half bricks. Their total length is 22 m.
- The number of interior doorways is 4. Their dimensions are 1.25 m x 2.1 m.
- The partitions are planned to be laid out with a thickness of 0.5. Their total length is 26 m.
- The planned thickness of the external walls is 2 double.
- The number of external doorways is 2 (1.3 x 2.15 m). Window – 7 (1.4 x 1.85 m).
Taking this data into account, in practice our calculation will look like this:
- (2 x 15 x 3) + (2 x 8 x 3) – (7 x 1.4 x 1.85) = 119.86 m² - area of the external walls;
- (22 x 3) – 4(1.25 x 2.1) = 55.5 m² - area of internal walls;
- (26x3) = 78 m² - area of partitions.
Using reference materials from the Internet, we learn that:
- for 1 m² of masonry in 2 doubles, 104 pieces will be required;
- for 1 m² of masonry of 1.5 one and a half square meters, 78 pieces will be required;
- for 1 m² of masonry with 0.5 standard single bricks, 51 pieces will be required.
Therefore, in total (taking into account combat and marriage) we will need to purchase:
- 1.08 x (119.86 x 104) = 13463 doubles;
- 1.08 x (55.5 x 78) = 4675 one-and-a-half pieces;
- 1.08 x (78 x 51) = 4296 standard pieces.
Not like that in a complicated way you can make the necessary calculation of the building material.

Brick calculator
To avoid interruption of the construction process due to a shortage of bricks and unwanted expenditure of funds on the delivery of purchased building materials, it is better to deliver everything at once. Excess material will significantly increase the cost of construction. Therefore, if you need to calculate bricks for masonry, the online calculator on the construction site is the best modern instrument for an accurate calculation.
The principle of determining brick consumption based on the volume of walls
The methodology is based on determining the quotient of dividing the total volume of walls (adjusted to take into account the deduction of openings for windows and doors) by the volume of one brick. The result is the required quantity in pieces for brickwork.
In practice, the problem is solved through several stages:
- determination of the areas of internal walls and partitions, external load-bearing walls, differing in thickness;
- calculation of the areas of window and door openings;
- subtracting the size of openings from the wall area;
- calculating wall volumes by multiplying their adjusted area by thickness;
- calculation of bricks for laying external, internal walls and partitions by dividing the resulting wall volumes by the volume of one brick.
The task is complicated by the fact that there are seams between the bricks that are filled with mortar. Their standard thickness is taken to be 10 mm, but it can be less if the brick has an ideal geometry. A few millimeters of mortar between bricks on the scale of the entire building grows into a rather impressive value, reducing brick consumption.
A simplified calculation is based on the standard dimensions of a single brick of “normal shape” (1NF) - 250 x 120 x 65 mm (length, width, height). In a cubic meter of masonry, exactly 512.82 pieces of such bricks fit. Taking into account the seams (10 mm), the difference will be 118 bricks, which for the entire facility represents a mountain of unnecessary material. Using an online calculator, the purchase of excess building materials will be eliminated.
Any batch of bricks initially has a certain percentage of defects. Losses are inevitable during loading, transportation and unloading. This damage increases the calculated amount by 5 – 8%.
An example of calculating the required number of bricks per unit area
Design solution one-story house(ceiling height - 3 m) assumes a rectangular outline with a length of 15 meters and a width of 8 meters. The initial data are also:
- length of internal load-bearing walls – 22 m;
- length of partitions – 26 m;
- number of doors in external walls – 2 pcs. (size 1.3 x 2.15 m);
- number of doorways in internal walls – 4 pcs. (size 1.25 x 2.1 m);
- number of windows – 7 (opening size 1.4 x 1.85 m);
- type of masonry of external walls - 2 bricks (double);
- internal load-bearing walls are designed to be 1.5 bricks (0.38 m);
- The thickness of the partitions is 0.5 bricks (0.12 m).
The calculations boil down to determining:
- 1.Adjusted area of masonry of external walls (without openings):
- S= ((2 x 15 x 3) + (2 x 8 x 3) – (7 x 1.4 x 1.85)) = ((90 + 48) – 18.13) = 119.86 m².
- 2. Areas of internal walls:
- V int.st. = ((22 x 3) – 4(1.25 x 2.1)) = 55.5 m².
- 3. Areas of partitions:
- V lane = (26x3) = 78 m².
Using a reference table, the value of how many bricks are in 1 m2 of masonry is determined:
Based on the fact that for a unit of masonry area of 2 bricks (using double bricks) 104 pieces are needed, then the external walls of the entire building must:
119.86 x 104 = 12466 pcs. double bricks.
For internal load-bearing walls of 1.5 bricks (one-and-a-half bricks) you need: 78 x 55.5 = 4329 pieces, where 78 is the average value showing how many one-and-a-half bricks are in 1 m2 of masonry with a thickness of 0.38 m.
For partitions of 0.5 bricks of material you will need: 78 x 51 = 3978 pieces of single brick.
That. single bricks need to be purchased 3978 x 1.08 = 4296 pieces, one-and-a-half bricks - 4329 x 1.08 = 4675 pieces, and double bricks - 12466 x 1.08 = 13463 pieces - taking into account 8% waste from breakage and scrap.
Using a bricklaying calculator, calculating the required quantity is reduced only to entering the initial data.

Types and sizes of bricks
The start of construction is preceded by the calculation and purchase of the required building materials. Correctly carried out calculations will prevent a shortage of material during construction or its excess during construction. large quantities. Experts recommend purchasing bricks one-time to avoid color discrepancies. To calculate the amount of material, you will need the following information:
- type of bricks used;
- masonry method, determined based on optimal thickness walls of future housing;
- the area of internal partitions and external walls of housing is calculated separately;
- The dimensions of future windows and doors are taken into account.
Depending on the purpose of the building, in what climatic conditions it will be located, choose the type of brick. Based on the material of manufacture, it is classified into the following types:
- Adobe products consist of clay and various fillers.
- Most common ceramic material from baked clay.
- Sand-lime brick contains sand and lime.
- The hyper-pressed material includes lime and cement.
- Clinker bricks are produced from special baked clay.
- Fireclay is the source of fireclay bricks.
Depending on the purpose of use, brick can be:
- Construction (private). Suitable for arranging interior and exterior walls of buildings. Considering its unattractive appearance and the likelihood of minor chips, when used externally, the walls of the future home are subject to insulation and protective finishing. The external condition of the product does not reduce its strength.
- The facing (facade, front) material is characterized by an ideal surface and the absence of defects. In the role facing material ceramic, silicate and hyperpressed products can be used. The maximum deviations in dimensions according to GOST are 2, 3 and 4 cm in height, width and length, respectively.
In places of high humidity (lowlands or natural areas with a cold climate), ceramic material is optimal due to its low hygroscopicity. From option sand-lime brick in this case it is better to refuse due to its hydrophobic properties. The most suitable operating conditions for silicate material are dry and hot latitudes. Facing brick, in turn, is divided into textured and façade materials.
Depending on the filling, bricks are divided into solid and hollow.
Size of all bricks produced by different manufacturers, has established standards: the width and length of the product do not change and are 120 and 250 mm, respectively, the thickness is available in 3 options:
- single - 65 mm;
- one and a half - 88 mm;
- double - 138 mm.
From an aesthetic point of view, single brick masonry is the most attractive. One-and-a-half and double thickness of the product helps simplify and speed up the housing construction process. In addition to this, it is observed significant savings consumable solution.
Masonry methods
To calculate the quantity required material The method of laying is of paramount importance. The main types of solid masonry are represented by the following options:
- The thickness of a half-brick wall is 12 cm. This method is used exclusively for internal partitions.
- A wall of 1 brick has a thickness of 38 cm.
- 51 cm - standard wall of 2 bricks;
- The wall thickness of 64 cm indicates a masonry of 2.5 bricks.
The walls of a home are subject to loads in three directions: compression, lateral rotation or displacement. In the first case, vertical forces from structures located above tend to flatten the wall. In low-rise private houses these loads are small and side surfaces have a sufficient margin of strength against compression. Rotational and horizontal forces occur as a result of soil pressure on the basement wall or increased cross winds. Such loads tend to displace a section of the wall from its occupied position. Housing with thin walls is at risk of cracking or even breaking. To ensure a margin of resistance to displacement forces, the increased thickness of the outer side surfaces is included in the design calculations. Considering climatic features Russian regions, the most acceptable is considered to be a laying of 2 or 2.5 bricks.
Calculation method
There are two main options for determining the amount of brick needed for housing construction:
- the thickness of the connecting seams is not taken into account;
- taking into account the size of the mortar joint, which ranges from 5 to 10 mm.
Calculation according to the first option usually leads to the formation of excess building materials. The second option is more economical, however, 10-15% is added to the result obtained in case of possible losses during construction.
We give the calculation procedure using an example with specific data:
- it is planned to build a 1-story brick house 9x10 m, 3 m high;
- laying of external walls in 2 bricks, 1 door 1x2 m and 4 windows 1.2x1.5 m are provided;
- a single brick is used, the thickness of the mortar joint on the outer side surfaces and partitions is 7 mm;
- internal partitions made of half a brick, two 10 m long, one 9 m long;
- partitions have 5 doors 1x2 m;
First of all, the amount of material for the outer side structures is determined. The calculation algorithm includes the following steps:
- Perimeter of load-bearing walls: (9+10)x2=38 m.
- Total area of external side structures: 38x3=114 m2.
- Total area of window openings and doors: 4x(1.2x1.5)+1x2=9.2 m2.
- Net masonry area of external walls: 114-9.2=104.8 m2.
- To calculate the amount of building material in 1 m2, we determine the area of the end part of one product: 0.12x0.065 = 0.0078 m2, respectively, in 1 m2 there will be 1/0.0078 = 128 products. Taking into account the laying method, the value doubles and the result is 256 pieces per 1 m2.
- For the construction of load-bearing side surfaces you will need: 104.8x256 = 26829 copies of the product.
The amount of material for internal partitions is calculated in a similar way:
- total area internal structures: 2x(10x3)+9x3=87 m2.
- Square internal doors: 5x1x2=10 m2.
- Net area of partitions: 87-10=77 m2.
- Area of 1 product (spoon part): 0.25x0.065=0.01625 m2.
- Quantity per 1 m2: 1/0.01625=61.5 pieces.
- For all partitions: 77x33.3=4736 pieces.
We determine the total amount of material for external and internal walls: 26829+4736=31565 pieces.
In the second option, when calculating the area of the brick, we add the size of the mortar joint:
- For external walls: (0.12+0.007)x(0.065+0.007)=0.00914
- Quantity per 1 m2: 1/0.00914=109.4 pcs., taking into account the laying of 2 bricks: 109.4x2=219 pcs.
- Total quantity for external walls: 104.8x219=22951 pieces.
- Area of the tray part of the brick for internal partitions: (0.25+0.007)x(0.065+0.007)=0.0185 m2.
- Quantity per 1 m2: 1/0.0185=54 pieces.
- Total quantity for internal partitions: 77x54=4158 pieces.
- Total for external and internal walls: 22951+4158=27109 pieces.
The results of calculating the total area of the external side surfaces allow you to purchase insulation, if it is provided for in the project. If you don’t want to make calculations on the amount of brick required yourself, an online calculator will come to the rescue.
Building brick is one of the most popular building materials in our country for the construction of residential buildings and other buildings for various purposes. Before starting the construction of any brick building, it is necessary to purchase the required amount of bricks, for which a preliminary calculation must be made. Correctly carried out calculations will allow you to avoid unnecessary costs for the purchase of excess building materials and avoid problems with their shortage during construction.
Before you start making calculations, you need to determine:
- type of brick used;
- method of laying bricks, depending on the required thickness of the walls of the house;
- the total area of the walls of the house (external and internal);
- the total area of all window and door openings in all walls of the house.
At the beginning of work it is necessary to carry out.
Main types of bricks and laying methods
Standard bricks produced today by various manufacturers have the same dimensions in length and width (25x12cm) and differ in thickness by:
- Single (0.65cm).
- One and a half (0.88 cm).
- Double (1.38cm).
Walls made of single bricks look the most aesthetically pleasing. However, the use of one-and-a-half or double-thick bricks can greatly speed up and simplify the construction process. At the same time, the consumption of masonry mortar used is also significantly saved.
The thickness of the walls of the house depends on the methods of laying bricks. They can be:
- half a brick (wall thickness 12cm);
- 1 brick (wall thickness 25cm);
- 1.5 bricks (wall thickness 38cm);
- 2 bricks (wall thickness 51cm);
- 2.5 bricks (wall thickness 64cm);
In the Russian climate, the most optimal wall thickness is 2 or 2.5 bricks.
Calculation of the required amount of bricks
Calculation of the amount of brick can be carried out in two main ways:
- Does not take into account the thickness of the mortar joint.
- Taking into account the thickness of the seam, which is usually from 5 to 10mm.
It should be borne in mind that when using the first method, there may be an excess of building materials by 25-30%. The second method is more economical, but it is necessary to add 10-15% to the calculated value to take into account possible brick breakage during construction.
For clarity, let’s carry out the calculation using a specific example: It is necessary to build a one-story brick house 8 by 10 m, with a wall height of 3 m and without internal brick walls. In the external walls there is one opening for the entrance door 1 by 2 m and three openings for windows 1.2 by 1.5 m. The thickness of the walls is two bricks from a standard single brick with a joint thickness of 5mm.
The first layer is placed on the waterproofing
The calculation procedure for the first method will be as follows:
- We determine the perimeter of the external walls: (8+10)*2=36m.
- We determine the total area of the walls of the house: 36*3=108 sq.m.
- We determine the total area of door and window openings: (1*2)+(1.2*1.5)*3=7.4 sq.m.
- We calculate the area of the brickwork of the walls: 108-7.4 = 100.6 sq.m.
- We determine the amount of brick in one square meter, for which we calculate the end area of one brick: 0.12*0.065=0.0078 and divide this value by one: 1/0.0078=128, after which we multiply by two (since the masonry will be 2 bricks). We get 128*2=256 bricks per 1 sq.m.
- We calculate the required number of bricks for building a house by multiplying the total area of the walls excluding openings by the number of bricks per 1 sq.m: 100.6*56=25753.6.
Thus, 25,754 bricks will be needed to build the walls of the house.
Carrying out the calculation using the second method, to determine the amount of brick in 1 sq.m, we add 5 mm to the standard brick dimensions (joint thickness): (0.12+0.005)*(0.065+0.005)=0.00875. Accordingly, the amount of brick in 1 sq.m will be: 1/0.00875*2=229 bricks. Multiplying this number by the total area of the masonry we get: 229*100.6=23037.4. Let's add to this value about 1500-2000 bricks per battle and we get the amount of bricks needed to build a house: approximately 24,500-25,000 bricks.
Layer mineral wool between load-bearing wall and facing layer - helps reduce the overall wall thickness
From the above example it can be seen that the second calculation method is more economical.
The calculation for other wall thicknesses is carried out similarly, taking into account the appropriate corrections. If you need calculate the number of foam blocks per house — .
