How to calculate brick quantity
Method: Bricks = net wall area ÷ nominal brick module area × waste allowance
- Measure net masonry area after openings.
- Use the brick module including the intended mortar joint.
- Add waste appropriate to bonds, cuts, breakage and matching.
Worked example
Using these planning inputs:
- Net wall area: 20
- Brick module length: 0.24
- Brick module height: 0.086
- Waste: 8 %
Bricks required: 1047
Reality check: Confirm the supplier’s bricks-per-square-metre figure and order one batch; piers, returns, sills and special bonds alter quantities.
Before you calculate
Use consistent units and the best measured inputs available. Real materials, equipment, site conditions and tolerances can change the result. Vaelden shows planning estimates; regulated, structural, electrical, plumbing, pressure and other safety-critical work still requires appropriate local compliance and professional advice.
