How to calculate bricks for a wall?

Step 1: Calculate wall area = Length × Height (in meters). Step 2: Subtract openings (doors, windows). Step 3: Multiply by bricks per sqm (55 for half-brick, 110 for full-brick). Step 4: Add 5-10% for wastage.

Brickwork Calculation — How Many Bricks Per Square Meter?

Published: July 15, 2026 • 7 min read

Accurate brickwork calculation is essential for every construction project. Order too many bricks and you waste money. Order too few and your site stops. This guide gives you the exact formulas for Indian standard bricks.

Indian Standard Brick Sizes

Type	Size (mm)	Size with Mortar (mm)
Standard (Modular)	190 × 90 × 90	200 × 100 × 100
Traditional	230 × 115 × 75	240 × 125 × 85

Bricks Per Square Meter

Wall Type	Thickness	Bricks/m² (Modular)	Bricks/m² (Traditional)
Half Brick Wall	4.5 inch (115mm)	50	55
Full Brick Wall	9 inch (230mm)	100	110

Step-by-Step Calculation

Calculate wall area: Length × Height (in meters)
Subtract openings: Doors (2.1m × 0.9m each) + Windows (1.2m × 1.2m each)
Multiply by bricks/m²: Net area × 55 (half-brick) or 110 (full-brick)
Add wastage: Add 5-10% for breakage and cutting

Example: Full Brick Wall

Wall: 10m long × 3m high, with 1 door (2.1m × 0.9m) and 2 windows (1.2m × 1.2m each)

Wall area = 10 × 3 = 30 m² Door = 2.1 × 0.9 = 1.89 m² Windows = 2 × (1.2 × 1.2) = 2.88 m² Net area = 30 - 1.89 - 2.88 = 25.23 m² Bricks = 25.23 × 110 = 2,775 bricks With 10% wastage = 2,775 × 1.10 = 3,053 bricks

Cement & Sand for Brick Mortar

Mortar Ratio	Cement per 1000 Bricks (bags)	Sand per 1000 Bricks (cft)	Use Case
1:4	1.8	10	Load-bearing walls, wet areas
1:6	1.25	9	Standard walls (most common)
1:8	0.9	8	Non-load-bearing partitions

Cost Estimation (2026)

Item	Quantity (per 1000 bricks)	Rate	Cost (₹)
Red Bricks	1000 nos	₹10/piece	₹10,000
Cement	1.25 bags	₹390/bag	₹488
Sand	9 cft	₹60/cft	₹540
Mason Labour	—	₹800/day	₹2,400
Helper Labour	—	₹500/day	₹1,500
Total			₹14,928
