Brick Calculator for a Wall
Estimate bricks and bags of mortar for any wall.
Brick walls are measured in square feet of face area. Standard modular brick uses ~6.75 bricks per sq ft; queen-size uses ~5.75. Type N mortar (medium strength) suits most above-grade veneer walls; type S is required for structural or below-grade brickwork.

How does the brick calculator work?
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%)
