Brick quantity estimator
Estimate rectangular wall bricks with mortar joints and openings.
A clear answer. Here’s how.
Net wall face area = length × height − openings. Divides by one brick’s nominal face area including one horizontal and vertical joint, then adds allowance and rounds up. A single face only; wall thickness, bond, corners and structural design are excluded.
