Frequently asked questions
- How many squares of siding do I need?
- Total the wall area, subtract doors and windows, divide by 100 to get squares, then add about 10% for waste. A 1,600 sq ft wall with 160 sq ft of openings needs about 15.8 squares with 10% waste.
- How much does siding cost per square?
- Installed cost varies widely by material — vinyl is the most affordable, with fiber-cement and engineered wood higher. Enter your quoted or estimated price per 100 sq ft square.
- Should I subtract windows and doors?
- Subtracting openings gives a tighter material estimate. Some installers order on gross wall area to ensure enough material and cover waste; if so, set openings to zero and rely on the waste allowance.
