How it is calculated
Bricks per sq ft = 144 ÷ ((face length + joint) × (face height + joint)). A standard modular brick (8 × 2⅔ in with mortar) needs about 6.75 per sq ft; an 8 × 16 in concrete block about 1.125 per sq ft.
Example
A 20 × 8 ft wall with one door (21 sq ft) has 139 sq ft and needs about 985 bricks with 5% extra.
These are estimates to plan your purchase. Check measurements on site and follow the manufacturer’s instructions and local building codes.
Frequently asked questions
Do I include the mortar joint?
