Brick Calculator
Estimate how many bricks you need from wall area, openings, brick size, mortar joint, and waste.
How to calculate bricks for a wall
Enter gross wall area, subtract openings, and use the actual visible face dimensions of the brick. The mortar joint is added to width and height to form each modular unit.
Bricks = net area ÷ ((length + joint) × (height + joint))
Joints, cuts, and waste
A larger joint mathematically reduces units per area. Waste covers cuts and breakage, but actual quantity depends on bond pattern, corners, and the selected brick.
Frequently asked questions
How many bricks fit in one square meter?
It depends on brick dimensions and joint thickness; this calculator uses your inputs rather than a universal count.
Can I subtract doors and windows?
Yes. Enter their combined area as openings.
Why are bricks rounded up?
A fractional requirement still needs a whole brick.
