Brick calculator | Brickwork calculation and brick estimation

In this article i will tell you how to calculate bricks in a wall. By the explanation describe below, you can make your own MS Excel Brick calculator program to calculate bricks in a wall.

1. We know that standard dimensions of brick is 9 inch x 3 inch x 4.5 inch.
2. Convert these dimensions into feet.
3. Now multiply these dimensions to get volume of a brick.
4. 0.75 feet x 0.25 feet x 0.375 feet = 0.0703125 cubic feet.
5. Bricks required for 1 cubic feet brickwork will be (1/0.070) =  14.285 bricks
6. 10% space of brickwork is covered by mortar.
7. Subtract 10% bricks from 14.285, 14.285-1.4285=12.85 bricks.
8. Add 5% wastage of bricks.
9. 5% of 12.85 is 0.64 bricks.
10. Add 0.64 and 12.85 to get number of bricks in 1 cubic feet, we get 0.64 + 12.85 =13.492 bricks or we can say that 13.5 bricks.

Number of bricks in 100 Cubic feet brickwork

As we know that there are 13.5 bricks in 1 cubic feet. So in 100 cubic feet there will be 1350 bricks.

How to calculate bricks in a wall ?

To calculate bricks in a wall, we need to know the dimensions of the wall. For instance, if a wall is 10 feet long with 10 feet height and 9 inch thickness. Then we can find its bricks in a following way. Multiply dimensions of wall. 10 feet x 10 feet x 0.75 feet. We will get 75 cubic feet. We have seen above that there are 13.5 bricks in 1 cubic feet brickwork. So there will be 75 x 13.5 =1012.5 bricks in 75 cubic feet. In this way we calculate bricks in any wall with the known dimensions.

Bricks calculation formula

Bricks calculation formula is written below.

In feet

• Length of wall in feet x height of wall in feet x thickness of wall in feet x 13.5 = number of bricks

In meter

• length of wall in meter x height of wall in meter x thickness of wall in meter x 500 = number of bricks

 Number of bricks in 1 Cubic meter brickwork

Standard dimensions of brick in metric units are 225 x 112.5 x 75 mm.

1. multiply these dimensions to get volume of a brick, 0.225 m x 0.1125 m x 0.075 m=0.00189 cubic meter.
2. In one cubic meter, number of bricks will be (1/0.00189)=529.1 bricks.
3. 10% of brickwork will be covered by mortar.
4. Subtract 10% bricks from the 529.1, we will get 529.1-52.91=476.20 bricks.
5. Add 5% wastage of bricks.
6. 5% of 476.20 is 23.80 bricks.
7. Add 23.80 and 476.20 to get number of bricks in one cubic meter brickwork.
8. 23.80+476.20=500 bricks.
