About the Brick Wall Calculator

Brick is one of the oldest and most enduring building materials, prized for its beauty, durability, and fire resistance. Whether you're building a brick veneer on a home, a garden wall, a brick mailbox, or an accent feature, knowing exactly how many bricks to order is essential for efficient construction.

This calculator determines the number of standard modular bricks needed for your project based on wall area. Standard modular bricks measure 3-5/8" × 2-1/4" × 7-5/8" and require approximately 6.75 bricks per square foot of wall (with standard 3/8" mortar joints).

The calculator includes a waste factor for cutting, breakage during delivery, and on-site damage. It also estimates the number of mortar bags needed, so you can order all materials at once.

When This Page Helps

Bricks are sold by the thousand, and each pallet costs hundreds of dollars. Under-ordering means a second delivery charge and potential color lot mismatch. Over-ordering means returning heavy pallets or storing them indefinitely. This calculator gets you to the right number.

How to Use the Inputs

  1. Enter the wall length in feet.
  2. Enter the wall height in feet.
  3. Subtract the area of any openings (doors, windows) if applicable.
  4. Set the waste factor (5% for simple walls, 10–15% for walls with many cuts).
  5. Review brick count and mortar bag estimate.
Formula used
Wall area (ft²) = Length × Height − Openings Bricks = Wall area × 6.75 (modular bricks per ft²) With waste: Bricks × (1 + waste %) Mortar bags ≈ Bricks ÷ 35 (80-lb bags)

Example Calculation

Result: 1,157 bricks

Net wall area = (25 × 8) − 20 = 180 ft². Bricks = 180 × 6.75 = 1,215. With 7% waste: 1,300. Mortar: 1,300 ÷ 35 = 38 bags of 80-lb Type S masonry cement.

Tips & Best Practices

  • Standard modular bricks run 6.75 per ft²; king-size bricks run about 4.5 per ft².
  • Order all bricks from the same lot to ensure consistent color; different kiln runs can vary noticeably.
  • A brick mason lays 400–500 bricks per day on average; plan your timeline accordingly.
  • Wet bricks slightly before laying in hot, dry weather to prevent them from sucking moisture from the mortar.
  • Keep a 3–5% surplus of bricks for future repairs — matching bricks years later can be very difficult.
  • Brick veneer walls need wall ties to the structural backing at 16–24" spacing.

Brick Sizes Reference

Modular: 3-5/8" × 2-1/4" × 7-5/8" (6.75/ft²). Queen: 3-1/8" × 2-3/4" × 9-5/8" (5.76/ft²). King: 3-5/8" × 2-5/8" × 9-5/8" (4.5/ft²). Utility: 3-5/8" × 3-5/8" × 11-5/8" (3.0/ft²). Always verify the actual brick dimensions with your supplier.

Bond Patterns

Running bond is the most common (each course offset by half a brick). Common bond adds a header course every 6th course. Flemish bond alternates headers and stretchers in each course for a decorative look. Stack bond is purely decorative and requires horizontal joint reinforcement.

Estimating for Openings

Subtract the opening area but add bricks for soldier courses (upright bricks) above windows and doors, and for rowlock sills below windows. These accent courses use more bricks per linear foot than standard running bond.
