Brick & Mortar Estimator Calculator
Estimate the exact number of standard bricks and 80 lb mortar bags required for single or double-wythe brick walls based on length, height, and recommended waste allowance.
Formula & Mathematical Methodology
Bricks = Wall Length (ft) × Height (ft) × Bricks per sq ft × (1 + Waste% ÷ 100)
Standard US modular brick construction requires approximately 7 bricks per square foot of wall surface area for a single skin (wythe). A standard 10% waste buffer accounts for cut end pieces and job-site breakage.
Step-by-Step Worked Example
Scenario: 20 ft long by 6 ft high single-wythe brick wall with 10% waste.
1. Calculate wall area: 20 ft × 6 ft = 120 sq ft.
2. Multiply by 7 bricks/sq ft: 120 × 7 = 840 base bricks.
3. Add 10% waste: 840 × 1.10 = 924 total bricks.
4. Estimate mortar: (924 ÷ 1,000) × 5.5 = ~5.1 bags → 6 bags of 80 lb mortar mix.
Final Calculated Result: 924 Bricks & 6 Mortar Bags
