Formula
Worked example
A 20 ft by 8 ft wall with a 20 ft² opening, standard modular brick dimensions, ⅜ in joints, and 5% allowance requires roughly 1,008 bricks; mortar volume is shown as a planning estimate.
What to keep in mind
- Mortar volume is an approximation and varies with bond, workmanship, joint profile, brick frogs/cores, and waste.
- Use project specifications and supplier yield data for procurement.
