The module
A 9×4.5×3 inch brick plus a half-inch mortar joint becomes 9.5×5 inches, so a square foot of 9-inch wall needs about 10.4 bricks.
Wastage
Order 5–8% extra. Bricks break in transport, and a second order arrives at a higher rate.
Soaking
Traditional fired bricks should be wetted so they do not pull water out of the mortar.
How many bricks for 1,000 sqft?
About 10,400 plus wastage — order 11,000.
Do machine-cut bricks differ?
Yes — measure a stack, the module changes.
