Introduction
Brick calculation is one of the most essential tasks in residential construction. Incorrect brick estimation can lead to material shortage, excess cost, and site delays.
In this complete guide, you will learn:
- Standard brick size
- Brickwork volume calculation
- Mortar deduction method
- Number of bricks required for 1000 sq ft house
- Common mistakes engineers make
Standard Brick Size in India
The commonly used brick size is:
190 mm × 90 mm × 90 mm
With mortar thickness, it becomes:
200 mm × 100 mm × 100 mm
Always confirm local brick size before calculation.
Step-by-Step Brick Calculation for 1000 Sq Ft House
Let’s assume:
Total built-up area = 1000 sq ft
Wall thickness = 9 inches (0.23 m)
Wall height = 3 m
Step 1: Convert Area to Square Meter
1 sq ft = 0.0929 m²
1000 × 0.0929 = 92.9 m²
Step 2: Calculate Wall Volume
Wall Volume = Area × Thickness
= 92.9 × 0.23
= 21.37 m³
Step 3: Number of Bricks per Cubic Meter
Standard bricks required in 1 m³ brickwork ≈ 500 bricks
(This includes mortar thickness)
Step 4: Total Bricks Required
Total bricks = 21.37 × 500
= 10,685 bricks
Add 5% wastage:
Final bricks required ≈ 11,200 bricks
Mortar Requirement
Dry volume of mortar = 30% of brickwork volume
= 21.37 × 0.30
= 6.41 m³
