Rounded up from the order area using coverage per unit.
Estimated material cost

Based on the order area after waste.
Calculates the total siding material needed for a house or building project, supporting three input modes: full house takeoff from perimeter and wall height, direct wall area entry, and gable-end-only calculation. It computes gross area, subtracts window and door openings, adds waste, and converts the result into siding squares, package counts, and estimated material cost.
Homeowners, contractors, and DIY builders planning a siding project who need accurate material quantities and cost estimates. Works with any siding material including vinyl, fiber cement, and engineered wood.
Depending on the selected mode, the calculator starts with perimeter × wall height (house mode), a direct wall area entry (area mode), or gable triangle area (gable mode). It adds gable area where applicable, subtracts openings, applies the waste percentage, and divides by 100 to get siding squares. Package counts are rounded up from the coverage-per-unit input, and cost is calculated from the price per square foot on the order area.
Assumes rectangular walls and simple gable geometry. Complex wall shapes, multiple stories, dormers, and curved surfaces may need manual adjustment. The cost estimate uses a single price per square foot and does not include labor, trim, fasteners, or disposal fees.
One siding square is a standard unit of measurement equal to 100 square feet of wall area. It is the same concept used in roofing and helps contractors communicate material quantities quickly. If your order area is 2,450 sq ft, that is 24.5 siding squares.
Calculate the exterior perimeter and multiply by wall height. Add the area of gable triangles (width x rise / 2), then subtract the total area of windows and doors. The calculator handles all of this math automatically in House mode—just enter the perimeter, wall height, gable dimensions, and openings.
Enter the 'Coverage per unit' (sq ft) found on the product packaging. The calculator will automatically round up to the nearest full box, panel, or board required for your order area. For example, if each vinyl box covers 24 sq ft and your order area is 1,200 sq ft, you will need 50 boxes.
A standard 10% waste allowance works for most simple, rectangular houses. If your house has many corners, gables, or you are using a material with a distinct pattern that requires matching, increase waste to 12-15%. The material presets include suggested defaults for each type.
The calculator works best for houses with rectangular walls and standard gable ends. For L-shaped or complex floor plans, use the Direct Area mode and enter the total wall area manually. You can also adjust the openings area to account for unusual features.
No. The cost estimate is material-only based on your price per square foot. Professional installation labor typically runs $1.50-$4.50 per sq ft depending on material and complexity. Always get multiple contractor quotes for a complete project budget.
Yes. The material presets only affect the suggested waste percentage and the package label. Your measurements stay the same when switching between Generic, Vinyl, Fiber Cement, or Engineered Wood, so you can compare takeoff results instantly.
