Engineering CalculationBrickwork Calculator - Bricks, Mortar, Cement and Sand per m³
Estimate bricks or blocks, mortar, cement and sand for a wall from its size and the brick and joint dimensions.
Open the calculator →Formula
Bricks per m³ = 1 / [(L + j) × (B + j) × (H + j)]
L, B, H = brick size (m), j = mortar joint thickness (m)
Worked example
Modular brick 190 × 90 × 90 mm with 10 mm joints
Bricks per m³ = 1 / (0.2 × 0.1 × 0.1) = 500 (before wastage)
