Estimating brick for a wall
With standard modular bricks and 3/8-inch mortar joints, plan on about 7 bricks per square foot of wall face. Measure the wall area, subtract large openings, and add 10% for cuts and breakage.
Don't forget the mortar
A wall of about 1,000 modular bricks needs roughly 8–10 bags of mortar mix. Buy a little extra mortar and a few spare bricks from the same batch so any future repairs match in color.
