Brick Calculator
Estimate how many bricks a wall or project needs.
Enter your wall dimensions to get the number of bricks needed, including a waste allowance for cuts and breakage. The default of 7 bricks per square foot suits standard modular brick in a single-wythe wall — adjust it for your brick size or bond pattern.
How it works
A standard modular brick with mortar covers about 1/7 of a square foot, so roughly 7 bricks fill one square foot of single-wythe wall. Multiply wall area by your bricks-per-square-foot figure, add waste, and round up.
Frequently asked questions
How many bricks do I need?
Multiply wall area by bricks per square foot (about 7 for standard modular brick) and add waste. A 20×8 ft wall needs about 1,232 bricks at 7 per sq ft with 10% waste.
How many bricks are in a square foot?
About 7 standard modular bricks per square foot of single-wythe wall, including mortar joints. Larger or thinner bricks change this.
How much waste should I allow for brick?
Plan for around 10%, more if your design has many cut bricks, arches, or decorative bonds.
