How to Measure Siding Area
To accurately calculate the amount of siding needed for your home or project, follow these steps:
- Measure the height and width of each wall in feet
- Multiply the height by the width to get the square footage of each wall
- Measure and calculate the area of all windows, doors, and other openings
- Subtract the area of openings from the total wall area
- Add a waste factor (typically 10%) to account for cuts and waste
This calculator simplifies the process by performing all these calculations automatically.
Siding Types and Considerations
Vinyl Siding
Low-cost, low-maintenance option. Weather-resistant and comes in various colors. Average cost: $3-7 per sq ft installed.
Wood Siding
Traditional appearance with natural beauty. Requires regular maintenance. Average cost: $6-12 per sq ft installed.
Fiber Cement Siding
Durable, fire-resistant, and looks like wood. Low maintenance. Average cost: $5-11 per sq ft installed.
Metal Siding
Extremely durable and low maintenance. Good for modern designs. Average cost: $4-8 per sq ft installed.
Brick Veneer
Classic appearance and extremely durable. Higher initial cost but very long-lasting. Average cost: $9-17 per sq ft installed.
Stucco
Texured finish that works well in dry climates. Relatively low maintenance. Average cost: $6-9 per sq ft installed.
Understanding Siding Terms
Square
A “square” is a unit of measurement used in construction that equals 100 square feet of material.
Waste Factor
The percentage of extra material added to account for cutting, damaged pieces, and installation errors.
Net Siding Area
The actual area that needs siding after subtracting windows, doors, and other openings.
Gross Wall Area
The total area of the walls before subtracting any openings.
