How to Calculate Bricks for a Wall
This brick wall calculator estimates the number of bricks, mortar bags (25 kg), total wall weight, and cost for walls of any size. Enter wall length and height in meters, centimeters, or millimeters, select a brick size (Standard 250×120×65 mm, Modular 190×90×65 mm, or custom dimensions), choose wall thickness and bond pattern, then subtract openings for doors and windows.
Brick Count Formula
Bricks per m² = 1 000 000 / ((brick_length_mm + joint_mm) × (brick_height_mm + joint_mm)). For a standard brick with 10 mm joint: 1 000 000 / (260 × 75) ≈ 51.3 bricks/m² per wythe. Double wythe doubles the count; 1.5-wythe multiplies by 1.5. Flemish and English bonds include header bricks in the calculation.
Mortar Estimation
A 25 kg bag of mortar covers approximately 40 standard bricks at 10 mm joints per EN 1996-1-1. The calculator adjusts mortar quantity for joint thickness, brick size, and bond pattern. Stack bond uses slightly less mortar than running bond due to aligned vertical joints.
