Brick Calculator
Estimate bricks and mortar bags for any wall size.
How the brick calculator works
Modular bricks (with a 3/8 in mortar joint) cover about 32 in² of wall face — roughly 4.5 bricks per ft². Multiply wall area by that rate, then add waste for cuts and breakage.
Formula: bricks = (L × H) × (144 ÷ face in²) × (1 + waste%)
