No of bricks required in India
Accurate estimation of bricks is pivotal in house construction in India and plays major role in construction cost . Recognizing brick types like Modular and Conventional, with dimensions such as 230mm x 110mm x 75mm, is foundational. For a standard 4″ brick wall, the thumb rule suggests 55 bricks per square meter, factoring in a 10% wastage allowance. Opting for a robust 9″ double-layer wall doubles the requirement to 110 bricks per square meter, ensuring structural integrity. This straightforward rule simplifies planning, aiding homeowners and builders in precise brick calculations for successful house construction.
Types of Bricks & Brick Dimensions
| Type of Bricks | Dimensions in mm | Dimensions in inches |
|---|---|---|
| Modular/Metric Bricks | 190mm x 90mm x 90mm | 7.48in x 3.54in x 3.54in |
| Non-Modular Bricks | 230mm x 110mm x 70mm | 9in x 4.33in x 2.75in |
| Conventional Bricks | 230mm x 110mm x 110mm | 9in x 4.33in x 4.33in |
| English Size Bricks | 230mm x 115mm x 75mm | 9in x 4.5in x 3in |
How many Bricks Required per 1 square feet
1brick areas is 32 sq inch,
so no of bricks required for 1 square feet for 4.5 inch wall is 144/32inch = 4.5 bricks
no of bricks required for 1 square feet for 9inch wall is 9-10 bricks .
How Many bricks required per 1 cft ?
4.5 inch Brick wall calculator
number of bricks per square meter
Size: 230mm x 110mm x 75mm (0.230×0.110×0.075 m)
Mortar Thickness: 10 to 15mm (0.01m)
By adding the thickness of the mortar
Length of Bricks in mm (L) = 230mm + 10mm = 240mm – 0.240m
Width of Bricks in mm (W) = 110mm + 10mm = 120mm – 0.110
Thickness of Bricks in meter (T) =75 mm + 10mm = 85mm - 0.085m
Length (L): 240mm – 0.240mWidth (W): 120mm - 0.120m
Thickness (T): 85mm - 0.085m
Area of Each Brick: 0.0204 sqm
No. of bricks in 1 square meter: 50 bricks
Consider 10 % as brick wastage
Number of bricks per square meter for 4.5 inch wall = 50 + 5 = 55nos/sqm
9inch Brick Wall or Double Layer
No. of bricks in 1 square meter for 4.5inch wall: 55
No. of bricks in 1 square meter for 9inch wall: 110 (twice the thickness of 4.5inch wall)
Application of Thumb Rule
Given: 4.5inch brick wall size = 3m x 3m
No. of bricks in 4.5inch wall of 9m2: 495 bricks
The thumb rule simplifies brick estimation, providing a quick way to calculate the number of bricks per square meter for different wall types.

A 9″ brick wall requires twice the number of bricks compared to a 4″ wall. The thumb rule suggests 110 bricks per square meter for a 9″ wall.
4.5 to 5 bricks per square foot
55 bricks are required for 1 square meter
Size of the brick = 9 inch×4.5 inch×3 inch
Size of the brick with mortar = 9.08 inch×4.58 inch×3.08 inch
, which is approximately 128 cubic
Volume of 1 cft = 1ftx1ft x1ft
= 12inx 12in x 12in = 1728 cubic inches
Volume of the brick with motor= L X B X H
Now, let’s convert cubic inches to cubic feet:
no of bricks = Volume in 1 cft / volume of 1 brick with motor
no of bricks =1
Number of bricks for 1 cft = 13.5 bricks
Total no of bricks required for 4.5 inch
For a square feet you will be required 4.5 to 5 bricks for a 4inch wall.
For a 9 inch wall 900-1000 bricks are required to construct 100 square-feet wall
