Starting the construction of their own housing, many people do not know how to calculate the number of bricks per house in order to eliminate material overruns or be left without it in the midst of construction.
The calculation should be made in such a way that it is possible to purchase material from one batch at once. In this case, there will be no need for additional purchase of bricks in the future. The fact is that products from different batches may differ in color, which will adversely affect the appearance of the building. For this, you need an accurate calculation of the brick for the house.

Wall thickness in calculations
To accurately calculate the number of bricks per house, you need to determine the required wall thickness. Products with a standard size of 250x120x65 mm can be laid in half, one and a half, two and two and a half bricks, while the wall thickness will be:
- in half a brick - 120 mm;
- in one brick - 250 mm;
- one and a half bricks - 380 mm;
- in two bricks - 510 mm;
- in two and a half bricks - 640 mm.
Building a house in domestic conditions involves optimal thickness walls in two and two and a half bricks.
After the thickness of the walls of the building is determined, the main parameters of the structure should be set. To do this, you need to specify the perimeter and height data. The product of these indicators will allow you to find out the total area of \u200b\u200bthe walls. For a more accurate calculation of how many bricks will go to the house, subtract the total area of the door and window openings. The result will be the area of the brick wall.
Brick sizes
The dimensions of the product have a direct impact on how much brick is needed to build a house. There are several types of products that differ in dimensions:
(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -388243-8", renderTo: "yandex_rtb_R-A-388243-8", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");
- single: length - 250 mm, width - 120 mm, height - 65;
- one and a half - 250 x 120 x 88 mm;
- double - 250 x 120 x 138 mm.
The acquisition of one and a half or double bricks will significantly affect the speed construction works by increasing it. But this can have an adverse effect on the aesthetics of the building as a whole. Single brick walls look more impressive and neat. Everyone chooses the size of the material used independently.
When calculating how many bricks are needed per house, do not forget about the number of mortar joints that have a certain height. When laying in two or two and a half bricks, the seam will have a height of 10 mm.
The table below will help you calculate correctly. required amount bricks for the construction of any structure. The data were calculated on the basis of domestic standards of artificial building material.
The necessary data from the table must be multiplied by the area of \u200b\u200bthe brick surface calculated in advance. The result will be the number of bricks that are needed for construction. We should not forget about defective products, which are in almost every batch. When buying a brick, it is worth adding about 7% of the amount of material received. total number bricks.
Brick for cladding
No less often the question arises of how to calculate a brick for a house, which is necessary not for construction, but for cladding. In this case, the consumption will correspond to the consumption of the total masonry, only half a brick. To do this, you need to know two sizes: jointing (seam) and brick. For example: a brick of standard size is laid, with a length of 250 mm and a height of 65 mm, the joint width is 10 mm. When calculating, it turns out that with the given indicators per 1 sq. a meter of surface needs to be used up 50-52 products.
Amount of solution
When calculating bricks, it is desirable to know the amount of mortar needed to build a house. The consumption of the composition can be determined as follows:
- for one cubic meter of masonry, 0.21 cubic meters are required. solution meter;
- the wall is laid in two bricks, then the amount of mortar per one cubic meter will be 0.24 cu. meters.
Often used in construction hollow stone, the voids of which must be filled with a solution, which significantly increases the amount concrete mix consumed per cubic meter of masonry. That's why standard value is 0.23 cu. meters.
(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -388243-7", renderTo: "yandex_rtb_R-A-388243-7", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");
It's important to know! The consumption of materials directly depends on the density of the solution. Concrete is diluted, as a rule, in the following proportion: 1.2 t quartz sand, 0.3 tons of cement M400 and water. If the solution is too liquid, this will adversely affect the thickness of the seam, significantly reducing it. This must not be allowed. Also, a too thick solution, which does not contribute to the quality adhesion of the material. Any deviations in the parameters of the seam can lead to the rapid destruction of the building.
A liquid or thick solution leads to the formation of cold bridges, condensation and wetting of the wall. In this case it won't help. additional insulation, no waterproofing layer. Therefore, it is very important to observe the required proportions of the solution and accurately calculate the volume required for construction.

An example of calculating the number of bricks for building a house of 100 sq. m
For example, before counting a brick for a house measuring 10 by 10 m, you need to decide how thick the walls will be. A house whose walls will be laid in two stones will require almost twice as much material as when laying in one brick. The size of the brick is also better to choose in advance.
The calculation of the number of bricks for building a house is carried out in a few simple steps:
- calculate the perimeter: 10x4=40 m;
- we find the area of the outer walls, for this you need to know the height of the ceilings, which is usually 3 m: 40x3 \u003d 120 square meters. m;
- choose the type of masonry and brick: the table shows that the consumption of a single brick in a double masonry per 1 cubic meter, taking into account the seams, is 204 stones, then, following the calculation formula: 120x204 = 24480 pieces.
That is, for the construction of a house of 100 sq. m you need to purchase 24480 bricks. Similarly, you can calculate the cladding of a building made in half a brick: 120 x 51 = 6120 facing bricks.
Using the instructions above, you can calculate brick house any area: 8 by 10, 10 by 12. The changes will be in the calculation of the perimeter of the building. For example, for a house of 80 sq. m:
- we find the perimeter of the walls: 2x8 + 2x10 \u003d 36 m;
- we calculate the area with a ceiling height of 3 m: 36x3 \u003d 108 square meters. m;
- we find the number of bricks needed to build a house8 8 by 10: 108x204 (single brick, laying in two stones) \u003d 22032 pieces.
Several Important Aspects
Also in each house there is a certain number of partitions and internal walls. No building is complete without a device ventilation system. Therefore, when calculating the amount of material, it is necessary to calculate the total area of \u200b\u200bthe internal walls and partitions, multiply the result obtained by the consumption of bricks per square meter of masonry. It is important to remember that the thickness of internal structures differs significantly from the thickness of external walls.
Poke dressing of the front part of the masonry with inside, requires a much greater consumption of bricks.

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 any construction brick building it is necessary to purchase the required amount of bricks, for which you need to make a preliminary calculation. Properly carried out calculations will allow you to avoid unnecessary costs for the purchase of unnecessary 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 desired thickness house walls;
- 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 produce.
The main types of bricks and laying methods
The standard brick, produced today by 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).
The most aesthetically pleasing look walls, built of single brick. However, the use of one-and-a-half or double-thickness bricks can greatly speed up and simplify the construction process. At the same time, the consumption of the mortar used for masonry is also significantly saved.
The thickness of the walls of the house depends on the methods of laying bricks. They can be:
- in half a brick (wall thickness 12cm);
- in 1 brick (wall thickness 25cm);
- in 1.5 bricks (wall thickness 38cm);
- in 2 bricks (wall thickness 51cm);
- in 2.5 bricks (wall thickness 64cm);
In the conditions of the Russian climate, the wall thickness of 2 or 2.5 bricks is considered the most optimal.
Calculation of the required number of bricks
The calculation of the number of bricks can be carried out in two main ways:
- Without taking into account the thickness of the mortar joint.
- Taking into account the thickness of the seam, which is usually from 5 to 10 mm.
It should be borne in mind that when using the first method, an excess of building material by 25-30% can be obtained. The second method is more economical, but at the same time, 10-15% must be added to the calculated value in order to take into account the possible brick breakage during construction.
For clarity, let us calculate specific example: It is necessary to build a one-story brick house 8 by 10m, wall height 3m and without internal brick walls. There is one opening in the outer 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 first layer is placed on the waterproofing
The calculation procedure for the first method will be as follows:
- We determine the perimeter of the outer walls: (8 + 10) * 2 = 36m.
- We determine the total area of the walls of the house: 36 * 3 \u003d 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 brickwork walls: 108-7.4 = 100.6 sq.m.
- We determine the number of bricks in one square meter, for which we calculate the area of \u200b\u200bthe end of one brick: 0.12 * 0.065 \u003d 0.0078 and divide this value by one: 1 / 0.0078 \u003d 128, after which we multiply by two (since 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, multiplying the total area of \u200b\u200bthe walls, excluding openings, by the number of bricks per 1 sq.m: 100.6 * 56 \u003d 25753.6.
Thus, 25.754 bricks will be needed to build the walls of the house.
When calculating according to the second method, to determine the number of bricks in 1 sq.m, we add 5 mm to the standard brick sizes (joint thickness): (0.12 + 0.005) * (0.065 + 0.005) \u003d 0.00875. Accordingly, the number of bricks 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: about 24.500-25.000 bricks.
Layer mineral wool between bearing wall and facing layer - helps to reduce total thickness walls
From the above example, it can be seen that the second calculation method is more economical.
The calculation for a different wall thickness is carried out in a similar way, taking into account the appropriate amendments. If you need calculate the number of foam blocks per house — .
Facing own house always begins with the calculation of the cost of work, it is understandable, pleasure is always costly, however, in order to bring everything into one estimate, we need to know how to calculate the amount facing brick on house.
You can do this in two ways:
- On one's own. Having calculated all the necessary values, taking into account all the nuances of the walls.
- With the help of special calculators, in which you just need to “drive certain data.
We consider the facade and walls of the house
Let's immediately decide that we are going to the whole house, and not just its facade. So it will be easier to visually and by example show how the calculations work, and from what moments we will move back.
For an accurate calculation, we will need two quantities:
- Size, dimensions of the material used.
- The size of the patch. In this case, it is a little difficult to guide it accurately, but we will start from the average thickness.
The standard size of stone used in building cladding is 250*120*65mm, we need the length and height, so we take the values 250*65mm. We will try to reduce the size of the stitching to the denominator - 10 mm, this is the most best option for masonry.
Important! It cannot affect the total amount of material in any way, so this indicator should not even be considered.
Standard sizes lead us to 51-52 pieces facing material in 1 square meter. In principle, by entering this data into the calculator for calculating facing bricks for a house, everything will be calculated instantly, but this will be the total area of \u200b\u200bthe walls and the total amount of material.
And here's the thing, the walls of any house are not only a solid surface, and we will have to count everything with our own hands, based on the fact that there are dimensions:
- Window openings. They are not always standard, and the shape and area of \u200b\u200bsuch an opening may be different on different sides of the building or on different floors, this will also have to be taken into account immediately when calculating.
- doorways, we have at least two doors, entrance and back, plus, possibly, a balcony.
Knowing how to calculate the amount of brick for facing a house, and knowing all the parameters of the walls, we get the final figure. Here you can immediately make a small footnote, the total area of windows and doors can be from 20% of the entire quadrature of the walls of the building.
architectural nuances
We often talk about facing material need to buy with some margin. It is clear that the most obvious reasons are stone breakage, or deformation, improperly behaved masonry.
However, there is another reason, these are architectural nuances that look great on paper, but are sometimes quite difficult to work with.
Even if the foundation of the walls is double silicate brick M 150, the material is unpretentious and simple, even they can make small ledges, parapets, extensions, that is, change the even plane of the walls.
By repeating the contour, we will have to take all this into account in the calculations, and even if very small changes, they will still require an additional brick.
Windows and rustication of corners
So, we figured out the walls, now let's move on to the window openings, because we can't leave them “naked”.
And for the rustication of the corners of the house and for framing the window opening, one simple formula can be used.
In it, the calculation of facing bricks is based on the length of linear meters of openings and its division by the height of the facing material.
We explain. First, we measure all openings. Once again, it reminds us of linear meters, that is, everything here is just plus. Next, we have the height of the stone, this is always the standard size, even if building brick used, 65 mm.
In addition, we add the thickness of the seam, 10 mm, and we get the following formula 1m / (0.065 + 0.01). According to calculations, this is 13.33 bricks per 1 running meter.
We carry out exactly the same calculations when we need to calculate the rustication of all corners, by the way, there may not be 4 of them.
Subtotal
We can reduce our calculations to several main positions, these are:
- 52 pieces per square meter walls.
- 14 pieces per linear meter of windows and corners.
- The working surface of the walls.
Knowing all the parameters, we can easily come to the necessary figures.
Additional calculations
If we have a terrace, for example, or a canopy, a veranda open type, that is, decorative columns, pillars, which are also included in our calculation of the number of facing bricks per house, as they should be in the same style direction as the facade.
A column measuring 38x38 centimeters, as the most common for a veranda and a canopy, will require us to 4 in one row with standard size 250*120*65 .
Again, we take into account in our calculations the thickness of the seam, which we try to keep within 10 mm. In general, the instructions are quite simple.
It is 118 bricks that we need for one column. Actually, knowing this figure, we further consider how much it will take for the rest of the columns.
There is one nuance here, which depends on the size of the pillar, if everything is simple with the walls, and there can be only one option for both calculations and masonry, then we can lay pillars in several types.
Advice! Do not pay attention to the mismatch in the size of the facing bricks. Just for walls can be used standard dimensions, and for the columns choose a torn corner brick, its dimensions are 220 * 90 * 65. In this case, the number of pieces of material will not change, only the size of the column itself.
Conclusion
Such close attention to the calculations is due to the fact that the price of the material is not the cheapest, and it is necessary to understand how much material to buy at once. This is where color plays an important role. We have noted more than once that bricks from different purchase lots may differ in color.
Conclusion
Knowing how to calculate the facing brick for a house, we can independently start the rest of the work, and keep the result in mind when choosing a material at a cost. The price per brick is always per piece. In the presented video in this article you will find Additional information on this topic.
Happy building!
When calculating the amount of bricks, it is important to consider that approximately 5% of the material will need to be written off for battle or possible marriage related to transportation. Therefore, we recommend that you immediately put it in the estimate and buy with a margin, since different batches may differ slightly, but still differ in appearance and other options.
Fence Calculator
The calculation of the fence will require you to determine its width and height. It is necessary to take into account the following norms: when laying in 1 brick, 52 pieces of brick are required per 1 square meter, with double laying, respectively, 104 pieces.
- Pillar. The size of a standard brick is 250*120*65. For laying 1 row supporting structure 380 * 380 mm we need 4 bricks. By dividing the height of the pillar by the height of the brick, we get the piece amount of the required material.
- spans. Their calculation depends on the type of masonry used. Most often, laying in one brick is used. Multiply the area of one section by 52 and get the required number of bricks.
How many bricks per square meter when building a house?
Before calculating the amount of bricks that will be required to build the wall of the house, you need to determine the thickness of the future walls. On the example of a standard BARRUM brick, 250 * 120 * 65 mm in size. You can lay in one brick, then the wall thickness will be 250 mm, two bricks - 510 mm, a brick floor - 120 mm, one and a half bricks - 380 mm and, accordingly, the width of the wall laid out in two and a half bricks will be 640 mm.
Find the area of all windows and doorways and subtract them from the total area and get the area of \u200b\u200bthe brick wall.
Considering standard height a seam equal to 10 mm, for laying a wall with an area of 1 square meter in two bricks, you will need 204 bricks, in two and a half - 255 bricks.
Knowing the consumption of bricks per 1 square meter, you can calculate how much of the total material will be required for construction. To do this, we multiply the norm by the area of \u200b\u200bthe brick wall.
Every time a construction project is started, one has to calculate the financial costs, regardless of whether it is done with one's own hands, with the help of neighbors or professional builders a house is being built. 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 a high-quality result by attracting a certified professional contractor. preliminary cost building a house can be calculated using an online construction calculator.
Methods of calculation for the performance of construction work
Calculations can be made in three ways:
- Measurements on the design area.
- Building area calculations.
- Definition by construction volumes.
The first two methods at the output give an overestimated estimate figure. It includes additional costs for the alleged overrun of the material, the allowable rise in the cost of its cost. The possibility of additional unforeseen expenses is taken into account.
The third approach (calculation by real volumes) is more accurate and objective. It takes into account the work that will be directly carried out. The volume of completion for each segment of the construction is considered. Therefore, at the stage of drawing up an estimate, the customer has the opportunity, without violating the project, to make his wishes for individual structures (for example, for ceilings, roofing). Deviations from the total cost are possible within 15%.
According to the last principle, unlike many other resources, a unique mathematical calculator for calculating the construction of a house from the website works.
Algorithms for calculating the online calculator for building a house
The calculation is based on simple mathematics. First, to determine the volume, you need to set the value of the width, length and height (thickness) of a certain structure.
Secondly, they take into account building codes and rules that apply to specific structures selected for the project.
Thirdly, it takes into account actual price on the materials used, the tools used, the equipment involved, the labor of specialists. It is important that the price Construction Materials We have a stable, no sharp jumps. This is possible due to the presence of its own warehouse-shop with materials.
Fourthly, the calculations are based on existing and approved drawings. Therefore, when designing a house on our construction calculator, you get a result that is associated with real projects. The constant practice of contract work allows us to take into account all, even small, current costs. That is why the construction cost calculations on this online calculator are more accurate than on similar services.
Fifthly, the reliability of the result is ensured by adding up individual calculations for each segment of the construction:
- laying the foundation;
- erection of walls and ceilings;
- roofing with the arrangement of the chimney;
- installation of stairs, windows, doors;
- facade design.
In addition, you can use our calculator to calculate the cost of construction or repair individual structures your home.
Features of the formation of the price of work for different elements of the structure
Foundation
Before starting the calculations, you need to decide on the type of its design. In the settings of our calculator, the following foundation options are provided:
- tape on piles;
- tiled monolith;
- monolith with plinth;
- with basement.
The design is selected taking into account the mass of the designed structure and the characteristics of the soil geology at the site.
Next, for calculations, you need to specify the dimensions of the desired building (width, length) and the thickness of the foundation. We get three figures: the price of the work, the cost of materials, the final cost. This result will appear at each 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 out ceramic brick;
- porous ceramic blocks.
It is worth knowing that the calculator will consider building a house from blocks a little more expensive than in the case of brickwork. But we advise you to initially choose the material according to the characteristics, and not the price.
Overlappings
The construction of floors is of particular interest with its ability to combine various options. The online construction calculator offers to separately select floors for the basement and floor. Also, the difference in design is presented to your attention:
- beams wooden or glued;
- concrete plates or monolith.
In your choice, it is important to proceed from general requirements to the building under construction and financial opportunities. With proper selection of floors, you can even save. 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 big weight. At the core attic floor you can use wood, less durable concrete, but cheaper. It will also improve thermal insulation.
If you insure as much as possible in terms of fire safety, it is better to turn to concrete partitions. However, it is important to take into account the possibilities load-bearing structures(foundation, walls) in terms of withstanding a significant load.
Roof and chimney
The difference in their assortment lies only in price and aesthetics. The elements fully perform their functions, regardless of the price. Pay attention to the following types of tiles:
- natural;
- composite;
- bituminous (soft);
- metal.
The latter variant is the most common in modern construction. The chimney can be chosen from brick, ceramic or stainless steel.
Stairs
The staircase is one of the elements of the house that cannot be defined in terms of 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 home construction calculator from the site is an accounting of the areas allocated for window and door openings. When you specify the number of windows and doors, the total cost of building a house according to the calculator will be lower due to a decrease in the calculated volumes of wall materials.
Exterior finish needed not only for the exterior, but also for its 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;
- technology " wet facade»;
- ordinary plaster.
The latter option is cheaper, but the plaster must be applied to walls that, due to their thickness, provide thermal protection.
Using the construction calculator on the site will help you not only present the cost of the work, but also develop a preliminary detailed design of an aerated concrete house. The accuracy of the calculations is guaranteed by the combination of theoretical calculations with real experience implementation of many construction projects.
