How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Room perimeter is computed as 2 × (Length + Width).
Doorways are deducted (standard 36 inches / 3 ft per opening).
Miter and scarf joint scrap allowance (10-15%) is applied, then converted into board counts for standard 8ft, 12ft, and 16ft lumber lengths.
