How to measure siding square footage.
To find the number of squares of siding needed for an installation measure each walls width and height in feet.
Multiply height by width for each area and add to get total square footage not covered with siding.
These lines should be measured in feet ft for square footage calculations and if needed converted to inches in yards yd centimetres cm millimetres mm and metres m.
Divide the total by 100 to find the number of squares of vinyl siding to order.
Enter this total square footage here.
Measure the height and width of each side.
Multiply height by width to get that side s surface area in square feet.
Measure the height h and length l of each gable.
Area of a square side length x side length answer side length x side length square area.
Add gsf to sf from step 1 to get total square footage tsq.
Multiply each length and height measurement to find the square footage of each wall then add them together to find the total square footage.
Divide the square footage by 100 to get the number of squares needed for the wall.
