Calculation Formula

Leather Needed (sq ft) = (Length × Width × (1 + Waste Factor/100)) / 144

Where:
Length and Width: Dimensions of your project in selected units
Waste Factor: Additional leather needed to account for cutting losses (typically 10-20%)
144: Conversion factor (12 × 12 inches = 1 square foot)
