Frequently Asked Questions
How do I measure a room?
Measure the longest length and width in feet and multiply. For L-shaped rooms, split and add.
Why show square yards too?
Carpet and some other materials are sold by the square yard — 9 sq ft per yard.
Do closets count?
Measure and add them separately if you are buying flooring that covers them.
