How Many Boxes of Vinyl Siding Would It Take to Cover 1600-Square-Foot House?

A 1600-square-foot house would require 16 squares of siding. Most vinyl siding companies place two squares in each box. The standard amount to add for waste is an additional two squares, so a 1600-square-foot house would need nine boxes of siding.

If the house has an excessive amount of windows or several triangular eaves, the waste could be higher than two squares, requiring an additional box of siding. A few companies sell siding boxes that contain only one square, changing the required amount of siding boxes from nine to 18. This is usually the case when ordering specialty vinyl siding.
