Estimated Necessary Number of Bricks in a Wall Construction

Bricks Calculator is a tool / device that is used to allow you to count the number of bricks you will need to complete a wall (Estimated Necessary Number of Bricks in a Wall Construction).

Even so, the traditional way to calculate the amount of brick is more practical, if it is to design a more complex wall.

Bricks Calculation For A Wall

Have you ever wondered how many bricks you need to build a wall?

For a contractor, knowledge in calculating the bricks is very important to save time, energy and cost to build a wall.

For a homeowner, this knowledge is also important to avoid being cheated by a contractor or home builder.

How to calculate the bricks needed to build a wall?

Before you use a Bricks Calculator to count a bricks for a wall, it is better for me to share with you the manual way to count the needed bricks to complete your wall.


  • First of all, you have to know what is the area of ​​the wall that you want to set up. Formula, sl x sw x bd.
  • Then, you need to know what length, width and the thickness of the brick. Formula, bl x bw x bt.
  • Finally, you must know how thick mortar to be used for connecting all the bricks.

Example for bricks calculation for a wall

You want to build a wall 30 ‘x 40’ and 5 inches thick. Multiply all. Therefore, you would multiply 30 x 40 = 1200 square feet.

Then, get the brick volume. For example, the bricks  are measured as bt = 3 “, bl = 8” . (Additional info: the size of a brick is according to your area.) Convert inches to feet. 3/12 x 8/12 = 0.16666 square feet.

The calculation for the amount of bricks.

Divide the volume of the wall, with brick volume. 1200/0.1666 = 7202.881 + + +. Then, well-rounded to more realistic figures of 7203 bricks.

1/2 inch thick mortar mortar = 5%
1 inch thick mortar mortar = 10%

Just in case you want to use 1/2 inch mortar to connect and attach brick, you can remove 1% of the total brick to allow filling mortar.

So, 7203 x 10/100 = 720.3, this amount is unnecessary bricks. Round this value to a more realistic figure, which is, 720 bricks.

Then to get the final amount, you should subtract the original brick of 8230 with unnecessary amounts of brick, 823 bricks.
7203 – 720 = 6483.

So you need 6483 bricks to complete a wall-sized 30 ‘x 40’ and 5 inches thick.

This calculation is for single layer brick. If you need double layer, just double the value by multiplying 6483 x 2= 12,966 bricks.
