Online calculator brick on masonry

Calculator brick home will help you to easily find the required number of blocks for construction of walls and all related elements of the structure. It is based on data Standards, recommendations and other normative acts. The resulting values have a minimum error and allow you to navigate during the trip to the hardware store.

We consider and take into account the following design:

  • wall;
  • Windows;
  • door;
  • the pediments (triangular, trapezoidal, pentagonal);
  • jumper;
  • nets.

How to use it?

First you need to decide what type of blocks you are going to use in the construction of houses. If you made the final decision that it will brick, then you need to specify its parameters and price:

  • type (ceramic, silica);
  • design (hollow, solid);
  • size (single, Queen, double, Euro, modular);
  • the price is a joke.

We recommend you to make some margin on the marriage battle and pruning. 3-5% is more than enough.

Then fill in all the fields in the "wall Settings". The calculation necessary to produce separately for the external (+ internal load-bearing walls) and separately for partitions, since they have different thickness walls. These and all other data, enter under the plan and documentation on your house.

  • the total length of all walls (with the same thickness of masonry);
  • the height of the walls in the corners (ceiling height);
  • the option of laying (0.5, 1, 1.5, 2, 2.5 bricks);
  • the thickness of mortar in masonry (10, 15, 20 mm);
  • masonry grid (the feasibility of using you have to define yourself).

At the main part of the calculator finishes, you can immediately scroll down and click "Calculate". The data will be correct for boxes with previously specified parameters.

If you want to know a more accurate value, we provide the opportunity to take into account Windows, doors, pediments, lintels and nets.

To activate you are interested in an item, click on the button "Add".

Fill in the parameters window and door, also putting the number of them.

  • height, cm;
  • width, cm;
  • quantity, PCs.

If the roof of your home is different from the flat, specify the characteristics Gables and quantity.

  • height, m (total);
  • the height between the bases, m (trapezoidal and pentagonal);
  • width of Foundation, m;
  • the width of the bases, m (trapezoidal and pentagonal).

The basis is called the line connecting the two opposite corners on the bends.

Jumpers are a link in the chain of masonry, and used for covering the openings of Windows and doors. Fill in the fields:

  • thickness, mm;
  • length, m;
  • quantity, PCs.

If you are going to strengthen the design of the house with nets made of reinforced concrete, add the appropriate item and enter values:

  • thickness, mm;
  • quantity, PCs.

Means that the width of the laying nets and jumpers will be the same as the width of the building block.

How to calculate the number of bricks manually?

In order to answer the question you must know the main types and sizes of bricks, methods of laying and, of course, the method of calculation. You should be familiar with this information, at least, in order to understand the process and be confident in the reliability calculations.

Types of bricks for construction

First and foremost, bricks are divided into two large groups depending on the material:

  • ceramic;
  • silicate.

Based on the red ceramic bricks lies made of high quality clay with minimum amount of impurities. After forming, it is fired in kilns at a temperature of from 1000 to 1300 degrees.

Silicate brick is made of quartz sand and lime. After pressing, it is exposed to water vapor at a temperature of 170-200 degrees and a pressure of 8-12 ATM. Also often it adds various impurities, for example, titanium dioxide allows to preserve the white color of the product during the decades.

It is also important to know what they can be , depending on the filling:

  • full-bodied;
  • hollow.

From the title it becomes obvious that the brick does not have cavities. It is most durable and it is used to build load-bearing walls. The rate of voidness is very small for ceramic brick is 5%, silicate – 12%.

Inside the hollow bricks contains two or more holes, which are used to retain heat and improve insulation. The rate of voidness can reach 40%. They are used to create partition walls or as cladding.

The last characteristic we are interested in is the dimensions of the brick. According to GOST 530-2012, ceramic bricks are divided into nine different sizes (NF), and silicate according to GOST 379-2015 – five. In Russia is very popular, only three of them:

  • single (1 NF) 250h120h65 mm;
  • one and a half (1.4 NF) and one half 250x120x88 mm;
  • double (2.1 NF) 250х120х140 mm.

Also widespread are two kinds of blocks:

  • Euro (0,7 NF) 250х85х65 mm;
  • modular (1,3 PF) 288х138х65 mm.

What size blocks to use when building, everyone decides for themselves. There are no structural differences, the house will be equally sturdy, if a mix of double, single brick. It is a fundamental aesthetic component, most prefer the classic single brick.

The only objective point that is really worth paying attention to is the timing of construction and the price of materials. As a rule, single and double bricks are cheaper, besides it reduces the amount of cement mortar required for laying. But because of the larger blocks requires less time for the construction of buildings.

How to choose the thickness of the brick wall?

The thickness of masonry is selected based on the structural features of the house and climatic conditions of the region.

According to SP 15.13330.2012 "Stone and reinforced masonry design" minimum thickness brick bearing wall is equal to 1/20 of the height of the floor, i.e. at the standard height of the ceiling in private house with 2.7 metre wall thickness will be not less than 2700 mm x 1/20 = 135 mm. let us Assume that we have a two story house and then the value will increase two times up to 270 mm.

Meanwhile, distinguish the main types of sets and the resulting the width of the wall:

  • in a half-brick – 120 mm;
  • one brick – 250 mm;
  • a half brick 380 mm (10 mm is added to the joint between the bricks);
  • two brick – 510 mm (10 mm per stitch);
  • two and a half brick – 640 mm.

It turns out that we need the brickwork and a half brick. But do not forget that in the normative document contains recommendations for minimum wall thickness. If you're going to build a house with a high roof ceramic tiles, and floors will be in the form of a monolithic plate, and on the second floor you will want to arrange a sports hall with massive equipment, you should consider the options with a wider type of masonry.

In addition, due to the fact that bricks are extremely dense material it has high conductivity. Empirically established that the most favorable conditions are achieved by following the thickness of the masonry and the outside temperature:

  • a half brick, up to -12 °C;
  • in two bricks to -20 °C;
  • two-and-a – half-brick- to -32 °C.

Calculation of brick house with his own hands

In order to solve a simple problem such as calculating the number of bricks for the walls, you need to know:

  • the length of the walls;
  • the height of the walls;
  • the thickness of the walls;
  • the standard size of a brick.

When we find the area, you will need to use tabular data. Nothing complicated, but let's look at an example.


  • square one-storey house with a length of 10 m and a floor height of 2.7 m;
  • the blocks used single;
  • the bearing wall thickness of 1.5 bricks.


  • the length of the outer wall 10 x 4 = 40 m;
  • the area of the outer wall 40 m x 2.7 m = 108 m2;
  • look at the table below, we draw attention to the walls in 1.5 bricks;
  • 108 m2 x 153 PCs/m2 = 16524 pieces.

Successful settlements and lightweight construction!
