Typical single-skin wall: ~60 bricks per m² (including joints).
Use 5–10% extra for cuts and breakage.

Enter wall size to estimate bricks needed.
This calculator assumes a single-skin brick wall with standard mortar joints.
For cavity walls, double-skin walls or complex openings, calculate each section
separately or consult a mason.
Standard Brick Sizes
Most bricks:
- 215 × 102.5 × 65 mm
Coverage:
- ~60 bricks per m² including mortar joints
Example
Wall: 4m × 2.5m = 10 m²
Bricks:
10 × 60 ≈ 600 bricks
Waste:
600 × 1.05 ≈ 630 bricks (5% waste)
Mortar Estimate
Standard mortar:
- ~0.03 m³ per m² of brickwork
Example:
10 m² × 0.03 = 0.30 m³ mortar
When to Increase Waste
- Decorative patterns
- Multiple window/door openings
- Uneven substrate
