DIY CalculatorOne square yard is 3 feet × 3 feet, or 9 square feet — so divide square feet by 9 to get square yards.
Good to know
- Square yards = square feet ÷ 9.
- Carpet comes in 12 ft wide rolls, so buy by the length of roll you need, not just the area.
- Add 10% for seams and pattern matching.
- Measure closets and doorways too.
