Brick wall material estimator
Brick Calculator
Estimate how many bricks to buy from wall length, height, openings, brick face size, mortar joint, waste allowance, and price per brick. Built for quick masonry material takeoffs before you call the supplier.

Brick count is a material estimate
Confirm brick type, bond pattern, corners, wall thickness, veneer ties, lintels, footings, local code, and supplier packaging before ordering. This calculator estimates face-brick quantity only.

Brick Calculator formula
Gross wall area = wall length × wall height
Net wall area = max(gross area - openings, 0)
Brick module area ft² = ((brick length in + joint in) × (brick height in + joint in)) ÷ 144
Base bricks = net wall area ÷ brick module area
Bricks to buy = ceil(base bricks × (1 + waste %))
Example
A 24 ft by 8 ft wall with 20 sq ft of openings has 172 sq ft net area. An 8 in by 2¼ in brick with a ⅜ in joint covers about 0.153 sq ft per module, so base count is about 1,127 bricks. With 10% waste, buy 1,240 bricks.
Brick Calculator FAQ
How do you calculate bricks for a wall?+
Multiply wall length by wall height, subtract openings, then divide the net wall area by the brick face area including the mortar joint. Add waste and round up because bricks are bought as whole pieces.
Should I include the mortar joint?+
Yes for a wall-count estimate. The calculator adds the mortar joint to the brick face length and height so the effective module matches the spacing on the wall.
What waste should I use for brick?+
Use about 5% for a simple clean wall, 8-10% for openings and normal cuts, and 12% or more for complex corners, breakage, pattern work, or limited supplier access.
Does this design a structural brick wall?+
No. This is a material takeoff for brick quantity and cost only. Wall ties, footings, reinforcement, lintels, veneer details, and local code are outside this estimator.
