How To Calculate Exterior Square Footage For Siding?


Start by measuring the height and width of each wall of the building. 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 total by 100 to find the number of squares of vinyl siding to order.


A square foot = 144 sq. in. Therefore, you divide the number of square inches total by a square foot (144 sq. in.), and you get your total square feet of siding in each panel: 1440 sq. in./144 sq. in. = 10 sq. ft. Sometimes, your exterior wall height will be a few inches taller than the height of accumulated panels.
