Use decimals if needed (e.g. 3.5).
Step 3
How to use this calculator
Enter net wall area. Subtract window and door areas for a closer count, then add a waste percentage for cuts.
What the math is doing
Brick count ≈ area in square feet × 7 × (1 + waste). Rounded up to whole bricks.
Frequently asked questions
Does this include queen or engineer sizes?
It targets modular; other sizes change bricks per square foot.
What waste should I use?
5–10% is typical on straight walls; complex patterns need more.
Are corners doubled?
This is a flat area model; add corner bricks separately if needed.
What about veneer vs structural wythes?
Multiply area by the number of wythes you will lay.
