How many bricks per square metre?

For a standard Indian brick (230×110×75 mm) with 10 mm mortar joints in a 230 mm wall: approximately 60–65 bricks per m² of wall face area.

How is brick quantity calculated?

Bricks per m³ = 1 / ((brick length + mortar) × (brick height + mortar) × (brick width + mortar)). Multiply by wall volume to get total bricks.

What wastage factor should I use for bricks?

10% wastage is standard for regular brick walls. Use 15% for corners, arches, or complex patterns where more cutting is needed.
