## How to Calculate Bricks Needed

### Formula

**Bricks = Wall Area / Brick Face Area × (1 + Waste%)**

Brick face area includes the mortar joint on one side and the top:

**Brick Face Area = (Brick Length + Mortar) × (Brick Height + Mortar)**

A standard modular brick is 8" × 2-1/4" with a 3/8" mortar joint. This gives approximately 6.75 bricks per square foot of wall.

Exemple Résolu

A wall 20 ft long and 8 ft high with standard modular bricks (8" × 2.25") and 3/8" mortar joints, 7% waste.

  1. Wall area = 20 × 8 = 160 sq ft
  2. Brick face area = (8 + 0.375)/12 × (2.25 + 0.375)/12 = 0.698 × 0.219 = 0.1528 sq ft
  3. Bricks needed = 160 / 0.1528 = 1,047 bricks
  4. With 7% waste = 1,047 × 1.07 = 1,121 bricks
