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. Also read about:

Bricks per square foot 

4.5 inch wall thickness 9 inch wall thickness 13.5 inch wall thickness
5.06 bricks 10.125 bricks 15.18 bricks

Bricks per square meter

4.5 inch wall thickness 9 inch wall thickness 13.5 inch wall thickness
57.16 bricks 114.32 bricks 171.48 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.

Length of wall (ft) Height of wall (ft) Thickness of wall (ft) Number of bricks
10 10 0.75 1012.5 bricks
15 11 0.75 1670.625 bricks
13 11 0.375 723.9375
12 12 0.75 1458 bricks

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. Also read about:

See the dimensions of bricks here.

  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.
