How the calculation works
Bricks = net face area ÷ [(brick length + joint) × (brick height + joint)]. Add allowance and round up.
A worked example
At 7⅝ × 2¼ in actual face and a ⅜ in joint, each module is 8 × 2⅝ in. A 100 ft² area needs about 685.7 bricks before allowance.
What to check before using the result
- Running-bond corners, returns and specials are not a complete cut schedule.
- Actual bricks differ; use your manufacturer dimensions.
