What unit of measure is typically used for carpet?

The unit of measure typically used for carpet is square yard. When carpet is sold, it is often rolled out in widths of 12 feet and is priced and measured in square yards because this helps to more accurately reflect the area that the carpet covers. Since a square yard is equivalent to a 3-foot by 3-foot area, this measurement aligns well with how carpet needs to be rolled, cut, and installed in residential and commercial spaces.

In contrast, while square foot is a common measurement for various flooring materials, it is less practical for carpet since it doesn't align with standard carpet roll widths. The choices that refer to square or cubic yards aren't applicable for carpet measurement in this context. A square yard offers a direct way for both pricing and purchasing, making it the universally accepted standard in the industry.
