Brick Calculator
Estimate number of bricks needed for a wall.
About the brick calculator
The brick calculator estimates how many bricks you need for a wall, accounting for mortar joints and waste allowance.
How to use this calculator
- 1
Measure wall dimensions
Measure length and height in feet.
- 2
Choose brick type
Standard, modular, and jumbo bricks have different sizes and coverage rates.
- 3
Add waste allowance
Add 10% for cuts and breakage. Complex patterns may need 15%.
How the calculation works
Standard brick: ~6.75 bricks/sq ft (with mortar). Modular: ~6.5. Jumbo: ~5.5. Multiply wall area by bricks per sq ft, then add waste.
Example: A 20 × 8 ft wall with standard bricks and 10% waste needs about 1,188 bricks.
Why use construction calculators?
Construction projects involve significant material costs. Overestimating wastes money; underestimating causes delays. These calculators use standard industry formulas to give you reliable estimates for concrete, lumber, drywall, paint, roofing, flooring, and more. Always add 5–15% waste allowance for cuts, mistakes, and irregularities.
How to get accurate results
Measure twice, calculate once. Use a tape measure for dimensions, and enter values in the units shown. For irregular shapes, break the area into rectangles and calculate each separately. When in doubt, round up — it's better to have a little extra material than to run short mid-project.
