Frequently asked questions
- How is carpet measured?
- Carpet is sold by the square yard. Multiply room length × width in feet, divide by 9, and add about 10% for waste and seams.
- Why is carpet sold in 12-foot widths?
- Most broadloom carpet comes in 12 ft rolls, so room layout affects how much you waste at seams.
