Brick Calculator
Estimate how many bricks a wall needs from its area.
Count the bricks you need
Ordering bricks for a wall means turning its area into a count, then adding a margin for cuts and breakage. Come up short and the job stalls; over-order and money sits in a pile.
Enter the wall’s length and height and it estimates the bricks at about seven per square foot, then adds a 10% waste allowance. A 20 by 8 foot wall needs roughly 1,232 bricks with waste.
