What Is a Carpet Calculator?
A carpet calculator estimates the amount of carpet needed for your rooms based on their dimensions. It converts measurements to square yards (the standard carpet measurement in the US), accounts for waste from cuts and seams, and calculates linear feet of carpet roll needed. Most carpet is sold by the square yard and comes in 12-foot or 15-foot wide rolls.
