Waste Analysis
Siding Waste Calculation Formula
Panels = (Total Wall Area ÷ Panel Coverage) × (1 + Waste%)
Calculate total wall area, divide by coverage per panel/bundle, then add waste factor. Always round up to full panels. Waste includes cuts, trimming, and mistakes.
Reducing Waste Tips
1. Measure carefully and double-check calculations.
2. Plan cuts to maximize panel usage.
3. Order 5-10% extra for repairs/matching.
4. Consider panel orientation for complex walls.
