How this calculator works
We figure wall area (length × height) and multiply by about 7 modular bricks per square foot — standard once 3⁄8-inch mortar joints are included — then add 5% for cuts and breakage.
What changes how much you need
- About 7 modular bricks cover 1 sq ft of wall face with standard joints.
- Brick sizes vary (modular, queen, king) — confirm "bricks per sq ft" for yours.
- Order 5–10% extra for corner cuts, openings, and breakage.
- Subtract large openings (doors, big windows) for a tighter estimate.
Frequently asked questions
How many bricks per square foot?
About 7 standard modular bricks per square foot of wall, including the mortar joints.
How much extra should I order for waste?
5–10%. Corners, cuts, and the odd cracked brick add up quickly.
Does this include mortar?
The count assumes standard 3⁄8-inch joints. For mortar, plan about 7 bags per 1,000 bricks.
