How much carpet/vinyl will you need?

Note: The carpet/vinyl calculator adds ten percent to your totals to account for closets and room irregularities. In general, it's a good idea to buy extra carpet/vinyl to allow for cutting, seaming, and pattern repeats.

Carpet and vinyl are mainly available in 12 foot widths. Rooms that are narrower than 12 feet must be considered at least 12 feet wide or you will not have enough material to complete the installation.
