Brick Calculator
Estimate bricks for a single-leaf wall from net wall area, brick face dimensions, mortar joint thickness, and waste.
- Bricks including waste
- 1,077
- Bricks per m²
- 51.282051
How the calculation works
Nominal brick face area = (length + joint) × (height + joint). Quantity = net wall area/nominal face area × (1 + waste/100), rounded up.
Inputs
- Net wall area, m²
- Brick length, mm
- Brick height, mm
- Mortar joint, mm
- Waste, %
Calculation details
Enter brick and joint dimensions in millimeters. Subtract openings from wall area. For multiple identical leaves, multiply the area by their count.
This estimates a straight wall showing the stretcher face. Bond patterns, corners, special units, and the detailed layout can change the quantity.
