Brick & Mortar Calculator for Wall Construction
Accurately estimating bricks, cement, and sand before starting wall construction prevents both costly material shortages mid-project and wasteful over-ordering. This calculator uses standard Indian brick masonry ratios.
Standard Brick Sizing
A standard Indian brick measures approximately 9×4.5×3 inches. Including a standard 0.5-inch mortar joint, this works out to roughly 13.5 bricks per cubic foot of wall volume for both half-brick (4.5") and full-brick (9") walls.
Mortar Mix Ratio
This calculator uses the common 1:6 cement-to-sand ratio for general brick masonry — a standard, cost-effective mix for non-load-bearing walls. Load-bearing or external walls in high-rainfall areas may use a richer 1:4 or 1:5 mix for added strength.
Frequently Asked Questions
Should I order extra material beyond this estimate? +
Yes — always add 5-10% extra for breakage, cutting waste, and on-site contingencies. This calculator gives the theoretical minimum requirement based on wall geometry.
Does this work for AAC blocks instead of bricks? +
No — AAC (Autoclaved Aerated Concrete) blocks are much larger and use a different thin-joint mortar system. This calculator is specifically for standard clay brick masonry with traditional mortar joints.
Why is the mortar ratio important? +
A richer mix (more cement, less sand) gives higher strength but costs more and can crack if used improperly. A 1:6 ratio is standard for typical residential walls; consult a structural engineer for load-bearing or seismic-zone construction.

Brick & Mortar Calculation Formula
Standard Indian brick: 230 × 115 × 75 mm. With 10mm mortar joint: effective size = 240 × 125 × 85 mm per unit. Bricks per sq metre = 50 bricks (for 115mm thick wall). Add 5–10% wastage.
Worked Example
Wall: 10m × 3m = 30 sq m, 115mm thick. Bricks needed = 30 × 50 = 1,500. Add 8% wastage = 1,620 bricks. Mortar (1:6 cement:sand): approximately 0.3 bags cement + 1.5 cu ft sand per sq m = 9 bags cement + 45 cu ft sand for this wall.
Tips
- Always add 5–10% extra bricks for breakage and cuts
- Fly ash bricks are lighter and better insulating than red clay bricks — increasingly common in India
- Get at least 3 quotes from suppliers — brick prices vary significantly by location and season
