Calculate the total square footage of all exterior walls, subtract windows and doors, then add 10% for waste. Vinyl siding is sold in 'squares' (100 sq ft units).
A square is a standard unit equaling 100 square feet of siding material. Most contractors and suppliers price vinyl siding by the square rather than per square foot.
Measure the width of the gable base and the height from the peak to the base. The area equals (width × height) ÷ 2 for triangular gables.
A 10% waste factor accounts for cutting around windows, doors, corners, and potential mistakes. Complex house designs may need 15% waste allowance.
The number of panels per square varies by manufacturer and panel size. Typically, you'll get 12-15 panels per square depending on panel width and exposure.
Subtract the area of windows, doors, garage doors, and any other openings that won't be covered with siding. Measure each opening and add them together.
Vinyl siding costs range from $100-$300 per square depending on quality and style. Add installation costs of $200-$500 per square for total project cost.
