How Brick and Mortar Quantities Are Estimated
This calculator estimates the number of standard UK bricks (215mm × 102.5mm × 65mm) required for a wall, including a 10% wastage allowance. Formula: Bricks = Wall Area ÷ (Brick Face Area + Mortar Joint). For a standard 10mm mortar joint, approximately 60 bricks are needed per m² for a half-brick wall. Inputs: wall length, height, and bond type. Outputs: number of bricks, number of mortar bags, and approximate cost.
