Square yards of carpet for a room
Carpeting a room? Enter the dimensions to get the square feet and square yards to order — carpet is usually priced by the square yard.
Square feet vs. square yards
Carpet is sold by the square yard (9 ft²). We convert for you and add waste for seams and the fact that carpet comes in fixed roll widths (usually 12 ft), which creates offcuts.
Frequently asked questions
How many square feet in a square yard of carpet?
9 square feet make one square yard.
Why do I need extra carpet?
Carpet rolls are a fixed width (often 12 ft), so fitting your room leaves offcuts; seams also need overlap.
