Brick Calculator
How many bricks for a wall? Enter the wall size, pick the brick size, and get the brick count with waste plus the mortar bags — counted by face area including the 3/8-in joint.
10% for cuts, breakage and spares. Use more for curves or arches.
Bricks for a 160 sq ft wall
1,153 bricks — 29 bags of mortar (80 lb) · 6.6 bricks per sq ft
Wall area: 160 sq ft (14.9 sq m). Each brick with its 3/8-in mortar joint covers 0.153 sq ft, so the wall takes about 1,049 bricks before waste. The mortar figure assumes roughly 40 bricks per 80-lb bag. Deduct large openings (doors, windows) from the wall area first — measure the wall, not the whole elevation.
Estimate. Brick sizes vary slightly by manufacturer — confirm the actual face size and the current price per brick before ordering.
Formula used: Bricks = wall area × bricks per sq ft × (1 + waste%). Bricks per sq ft = 1 ÷ face area of one brick including its 3/8-in joint. Mortar bags = bricks ÷ 40, rounded up.
How this estimate works: A brick wall is counted by face area: each brick plus its mortar joint covers a fixed number of square feet, so dividing the wall area by that figure gives the exact count. Waste is added for cut bricks at ends and corners, breakage, and a few spares — brick dye lots vary, so spares from the same batch matter.
