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. brick calculator, brickwork calculation and brick estimation

  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.

Bricks per square foot

Wall thickness

Bricks per square foot

4.5 inch 5.0625 bricks
9 inch 10.125 bricks
13.5 inch 15.1875 bricks

Bricks per square meter

Wall thickness

Bricks per square meter

4.5 inch 57.16 bricks
9 inch 114.329 bricks
13.5 inch 171.49 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.
