How to calculate brick quantity
This calculator estimates the total number of bricks needed for a wall based on its area and your brick's coverage rate — the count that determines how many bricks to order for a veneer or full masonry wall.
How the calculation works
Bricks needed = Wall area × Bricks per square foot. The bricks-per-square-foot figure depends on brick size and mortar joint thickness; a common modular brick with standard 3/8-inch joints works out to roughly 6.5-7 bricks per square foot, though this varies by brick dimensions.
Example
A wall with 320 sq ft of area at 7 bricks per sq ft: Bricks needed = 320 × 7 = 2,240 bricks. Adding a typical 5-10% waste allowance for cuts and breakage would bring a real order to roughly 2,350-2,465 bricks.
Frequently asked questions
How many bricks fit in a square foot?
It depends on brick size and mortar joint thickness, but standard modular brick with 3/8-inch mortar joints commonly works out to around 6.5-7 bricks per square foot. Check your specific brick's spec sheet for an exact figure.
How much extra should I order for waste?
5-10% is a common allowance for cuts and breakage on a straightforward wall; walls with many openings, corners, or decorative patterns may need more.

Pro Tips for Brick Quantity
- Check your specific brick's coverage rate rather than assuming a standard number — brick dimensions and mortar joint width both shift how many bricks fit per square foot.
- Add 5-10% to your calculated total for cuts, breakage, and waste, especially around openings like windows and doors where more cutting is required.
- Subtract door and window openings from your wall area first for a more accurate brick count on walls with significant openings.
Common Brick Quantity Mistakes to Avoid
- Using a generic bricks-per-square-foot figure without checking it against your actual brick's dimensions and intended mortar joint width, which can meaningfully shift the real coverage rate.
- Not adding a waste allowance, which almost always results in running short since cutting bricks around openings and corners inevitably wastes some material.
