It’s the easy way to know exactly how many bricks to order before you start building.
How to Use the Brick Calculator
Enter your wall length and height in feet and choose the brick or block size. The calculator works out the wall area and how many bricks you need, including a waste allowance for cuts and breakages. It works for standard bricks as well as larger blocks.
How Many Bricks Per Square Foot?
A standard modular brick covers roughly seven bricks per square foot of wall once mortar joints are included. Larger bricks and blocks cover more area each, so fewer are needed. Choosing the right size above gives you an accurate count for your project.
