Siding Calculator

Siding Calculation Formula

\[ A_{tot} = \left( B \times H - (n_1 \times A_1) - (n_2 \times A_2) \right) \times (1 + w) \]

Where:

• \( B \) = Width of the wall (m)
• \( H \) = Height of the wall (m)
• \( n_1 \) = Number of doors
• \( A_1 \) = Area of a single door opening (m²)
• \( n_2 \) = Number of windows
• \( A_2 \) = Area of a single window opening (m²)
• \( w \) = Waste factor (%)
• \( A_{tot} \) = Total area of siding needed (m²)
