How to Calculate Bricks for a Wall

Formula

Standard bricks require about 7 per square foot with 3/8-inch mortar joints. Always add 5-10% for waste from cutting and breakage.

One 60-lb bag of mortar lays approximately 125 standard bricks. Factor in openings like doors and windows to avoid overbuying.

Common use cases:

  • Exterior brick wall construction
  • Garden wall building
  • Brick fireplace surround
