How it's calculated

Bricks per area = 1 ÷ ((brick length + joint) × (brick height + joint))
Bricks = (wall area − openings) × bricks per area × (1 + waste %)

Counts the bricks for a single-leaf (half-brick) wall from its face area, the brick's face size and the mortar joint: a UK 215 × 65 mm brick with a 10 mm joint is about 59 per m², a US modular brick about 6.9 per ft². Double it for a wall two bricks thick. Order 5–10% extra for cuts and breakage.
