How to use
A standard brick face (with mortar) is about 0.11 ft². Enter the wall length and height and the calculator returns bricks needed with a 7% waste margin for cuts and breakage.
FAQ
Does this count the mortar?
Yes — the 0.11 ft² figure already includes the ~3/8-inch mortar joint, so the count matches laid brick.
What waste is normal for brick?
5–10% covers cutting and the occasional damaged brick.
Is this for a single or double brick wall?
Single wythe (one brick thick). Double the count for a two-brick cavity wall.
