Brick Wall Calculator Guide
Understanding Brick Calculations
Calculating bricks isn't just about the area of the wall; it's about the size of the brick, the thickness of the mortar joint, and the type of wall (single vs. double skin). A precise calculation ensures you order enough bricks from the same batch to avoid color mismatches.
The Core Variables
- Wall Area: Length × Height of the wall.
- Brick Size: Standard US modular bricks are typically 7 5/8" × 3 5/8" × 2 1/4".
- Mortar Joint: Usually 3/8" or 1/2". This space adds up significantly over a large wall!
Bricks per Sq Ft ≈ 7 (for standard modular bricks with 3/8" mortar)
Total Bricks = Wall Area (sq ft) × Bricks per Sq Ft × (1 + Waste %)
Don't Forget the Mortar!
Mortar Calculation Rule of Thumb
For standard modular bricks with 3/8" joints:
- 1,000 Bricks require approx. 1 Cubic Yard of sand.
- 1 Bag of Cement (Type N) lays approx. 40-50 bricks.
Waste Factors
Bricks break during transit and cutting. Mortar falls off the trowel.
- Bricks: Add 5-10% for breakage and cuts.
- Mortar: Add 10-20% for waste (it's messy!).
