How to calculate
Estimate brick quantity from wall and brick-face dimensions.
bricks = ceil(wall area ÷ nominal brick face area × (1 + waste))
Worked example
Wall length (m): 8; Wall height (m): 2.5; Brick face length (mm): 215; Brick face height (mm): 65; Mortar joint (mm): 10; Waste allowance (%): 7.
Wall area: 20 m²; Bricks including waste: 1,269 bricks.
Assumptions and limits
This is a face-area estimate. Wall thickness, bond, piers, cuts, openings, and local brick dimensions affect actual quantity.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimate brick quantity from wall and brick-face dimensions. The result follows the displayed formula and keeps every adjustable assumption visible.

Frequently asked questions
What can change the brick wall material result?
This is a face-area estimate. Wall thickness, bond, piers, cuts, openings, and local brick dimensions affect actual quantity.
Should I round the inputs first?
No. Enter the best measurements available and round only the practical final quantity, such as full packs, boards, sheets, or components.
