Estimating brick quantities means accounting for more than just brick size — the mortar joint between bricks adds real area to each brick's effective footprint, and skipping this step leads to under-ordering.
This calculator takes your wall area, brick dimensions, and mortar joint thickness, and tells you how many bricks to order.
How it works
Enter your wall area, brick length and height, mortar joint thickness, and a waste allowance. The tool adds the joint thickness to each brick dimension to find its effective coverage, then divides your wall area (plus waste) by that coverage.
- Enter wall area (sq ft).
- Enter brick length (in).
- Enter brick height (in).
- Enter mortar joint (in).
- Enter waste allowance (%).
- Click Calculate to see your results.
Examples
A 200 sq ft wall
A 200 sq ft wall using standard 8"×2.25" bricks with a 3/8" mortar joint and 10% waste needs about 1,441 bricks.
Who should use it
- Estimating material needs before a brick veneer or wall project.
- Comparing costs between different brick sizes.
Industry applications
- Residential and commercial construction
- Masonry contracting
Advantages
- Accounts for mortar joint thickness, not just raw brick size.
- Includes a waste allowance for a more realistic order quantity.
Limitations
- Assumes a standard running-bond layout — decorative or complex brick patterns may need a different calculation.
Common mistakes to avoid
- Using a brick's raw dimensions instead of its effective coverage (brick size plus mortar joint) when estimating quantity.
- Not adding a waste allowance for cuts at corners, openings, and wall ends.
Best practices
- Order a few extra bricks beyond the calculated amount from the same batch, in case of breakage or future repairs — brick color can vary between production runs.
Tips
- If ordering from a supplier, ask whether bricks are sold individually or by the pallet/cube — you may need to round up to a full unit.
