Calculate Number of Bricks Required for a Wall
To Calculate Number of Bricks required for a wall we must know these four things:
- Unit of Measurement: The unit of measurement can be in meter or feet so we should must know that in which measuring unit we calculated or will calculate the wall length and height.
- Wall Type: Secondly we should know that either it is half brick wall or it is one brick wall.
- Size of the Wall: Third thing we should know that what is or will be the length and height of the wall. That can be easily measured physically on site or can measured through plan drawing using software’s like PlanSwift, Bluebeam, or AutoCAD.
- Standard Size of Brick: Lastly We should know what is the size of the brick you are going to use.
Now we know all the basic details which are required to find brick quantity for a wall.
Bricks Calculation Formula and Method
Difference Between Half Brick Wall and One Brick Wall
First of all we have to understand what is the difference between Half Brick Wall and One Brick Wall:
- Half Brick wall: Width of wall is equal to the brick width. Like for UK wall width is 102.5mm as brick width is 102.5mm.
- Full Brick Wall: Wall width is equal to the length of the brick or Width of the brick multiple of two + 10mm (Mortar Width) in most cases. Like in UK Brick length is 215mm and Width is 102.5mm so wall width is 215mm= (102.5 x 2) + 10mm.
- Note: This thumb rule doesn’t apply in just few cases like US the Mortar Width between the wall layers in width will be more then 19mm.

Bricks Calculation Formula
To calculate number of bricks required for a wall use Brick Calculation formula which is
Number of Bricks in Wall = Volume of Wall / Volume of Brick with Mortar ———- ( Eq # 01)
where as
Volume of Wall= Length of Wall * Width of Wall * Height of Wall ———– (Eq # 02)
Note: Volume of Brick with Mortar is different in Half Brick Wall and One Brick Wall.
For Both types of wall either Half brick wall or One Brick Wall the Length and Height of the brick with mortar can be calculated using came formula
Length of Brick with Mortar = Length of Brick + Mortar width = Length of Brick + 10mm (Standard Mortar Width Between the Bricks). Use this mortar calculator to estimate the required mortar for your wall.
Height of Brick With Mortar = Height of Brick + Mortar Height = Height of Brick + 10mm ( 10mm is the standard mortar between the bricks)
Where as
Width of the Brick with mortar for Half Brick wall and One brick wall is different so it is discussed above in detail.
Volume of Brick for Half Brick Wall = ( Length of Brick + 10mm) * (Width of Brick) * (Height of Brick +10mm)
Volume of Brick for One Brick Wall = ( Length of Brick + 10mm) * (Length of Brick) * (Height of Brick +10mm)
