 # How to calculate quantity of bricks in wall ?

To use the brick calculator manually we need some data for calculating no. of bricks.

Required Data:

• Volume of the wall.
• Volume of a standard brick.
• Details of openings in the wall.

Let’s assume

Length of the wall = l = 4 m

Height of the wall = h = 3 m

Thickness of the wall = b = 200 mm = 0.2 m

Assuming that the wall has no openings.

Brick size = 190 mm x 90 mm x 90 mm (without mortar)

Volume of brick masonry in wall = lxhxb = 4 x 3 x 0.2 = 2.4 m3

Volume of one brick with mortar = 0.2 x 0.1 x 0.1 = 0.002 m3

Number of bricks = [Volume of brick masonry/volume of one brick]

= 2.4 / 0.002 = 1200 bricks.

Consider 5% wastage of bricks.

Thus, the number of bricks required for 1 cubic meter = 500

#### Example 2 (Brick Calculator In Feet Unit):

You can use the same brick calculator for different units. In this example, We will use the feet unit.

##### 1. First,calculate the volume of the wall to be built:

Let us assume,

The length of the wall (l) = 10 feet.

The height of the wall (h) = 10 feet.

The thickness of the wall (b) = 200 mm = 0.656 feet.

Calculate the volume of the wall by multiplying the length, height, and thickness.

Volume of the wall = l×h×b = 10×10×0.656 =65 Cu.F

##### 2. Calculate the volume of one brick

We will use standard Indian bricks for the calculator.

The standard size of a brick (IS Standard) is 190 mm ×90 mm ×90 mm and

with the mortar joints, it becomes 200mm × 100 mm× 100 mm.

l = 200 mm= 0.656168 ft.

b = 100 mm =0.328084 ft.

h = 100 mm = 0.328084 ft.

Volume of the brick = l× b×h =  0.656168× 0.328084× 0.328084 = 0.0706 Cu.F

3. To find out the total nos of brick divide the volume of the wall by the volume of the brick.

No. of bricks required = 65.6/0.0706 = 929 no. of bricks.

#### Note:

1. Consider 5% wastage of bricks.

2. If the wall has any openings such as doors, windows, etc subtract the volume of the openings from the volume of the wall and then divide it by the volume of brick.
