About this calculator
Estimate bricks for a wall after openings and waste.
Brick size, bond and mortar joint affect the rate.
Formula
Bricks = net wall area × bricks per m² × (1 + waste%).
Example
Use a supplier/project rate when known; 60 bricks/m² is only a common planning figure for some standard bricks.
Accuracy
NUMTX shows the assumptions next to the calculation so you can replace defaults with values that match your situation. For measurements, supplier rates, fees, interest, tax or regulated work, confirm important figures with the appropriate official or professional source.
