How the Calculator Works

Our brick calculator uses industry-standard formulas to determine the exact number of bricks and mortar bags needed for your project. The calculation accounts for wall area, brick size, mortar joints, and a waste factor for cuts and breakage.

Formula

Wall Area (sq ft) × Bricks per sq ft × (1 + Waste %) = Total Bricks

Total Bricks ÷ 1000 × 7 = Mortar Bags (80 lb)
