About the brick calculator
Brick quantities depend on the wall’s face area and the size of each brick plus its mortar joint. This calculator works for a single layer (wythe); double it for a two-layer wall.
How to use this calculator
- Enter wall length and height.
- Enter brick length and height (face dimensions).
- Set the mortar joint and waste.
Worked examples
- Area: 80 sq ft
- Brick + joint: 8 × 2.625 in = 0.1458 sq ft
- 80 ÷ 0.1458 = 548.6; +5% = 576.1
About 577 bricks.
