Frequently Asked Questions

How many bricks do I need per square foot?

For a standard modular brick with a 3/8 in mortar joint, the mortar-inclusive face is 8 Γ— 2.625 inches (21 sq in), which works out to approximately 6.86 bricks per square foot. Other brick types have slightly different counts β€” use the calculator above to get the exact number for your chosen brick.

Does this calculator include mortar joints?

Yes β€” each brick type's dimensions already include a 3/8 inch mortar joint added to both the width and height. This means the calculation reflects real-world installation spacing, not just the bare brick face size.

How much extra brick should I order?

A 10% waste allowance is the standard recommendation for straightforward walls. Budget 15% for projects with lots of cuts around openings, curved sections, or detailed patterns. It's far less expensive to over-order and return unused bricks than to run short mid-project.
