Brick Calculator
A brick wall needs about 6.9 standard modular bricks per square foot, plus 5% for waste. Enter your wall size and subtract any openings to get bricks, mortar, and cost.
How to estimate brick quantity
Find the wall area by multiplying length by height, subtract the square footage of any windows and doors, then multiply by 6.86 bricks per square foot for standard modular brick. Add 5% for breakage and cutting. For odd-shaped gables, total the pieces with the square footage calculator.
Mortar bags
Mortar use depends on joint width, but a good planning figure is 125 bricks per 80 lb bag. Wider or struck joints use more material, so the calculator rounds up to whole bags.
Brick cost
Multiply the brick count by your price per brick. Common brick runs $0.40–$0.90 each, with face and handmade brick costing more. For ground-level paving instead of a wall, use the paver calculator.
Frequently asked
How many bricks do I need per square foot?
A standard modular brick covers about 6.86 bricks per square foot of wall once the mortar joint is included. Queen and king sizes need fewer; thin brick veneer needs about the same.
How do I account for windows and doors?
Measure each opening in square feet and enter the total in the openings field. The calculator subtracts that area before working out the brick count.
How much mortar do I need for brick?
One 80 lb bag of mortar typically lays around 125 standard bricks. Soft or wide joints use more, so round up and keep a spare bag.
