Frequently asked questions
Multiply the wall area by the bricks per square foot and add wastage. A 100 sq ft wall at 7 bricks per sq ft with 5% wastage needs about 735 bricks.
It depends on brick size and wall thickness. A standard single-brick wall is roughly 7 bricks per square foot; check your brick's dimensions for accuracy.
Bricks chip and break during handling and cutting, so a 5–10% allowance avoids running short partway through the job.
The bricks-per-square-foot figure already assumes normal mortar joints, so the count reflects a built wall, not bricks packed tightly together.
