Square Feet to Square Yards Calculator
This square feet to square yards calculator converts an area in either direction and prices it if your material is sold by the square yard.
Divide square feet by 9 to get square yards, because a square yard is 3 ft × 3 ft. A 450 sq ft room is 50 square yards; at $24 per square yard, carpet for it costs $1,200 before waste.

How to convert square feet to square yards
A square yard is a square that measures 3 feet on each side, so it holds 3 × 3 = 9 square feet. To convert, divide by 9; to go back, multiply by 9.
square feet = square yards × 9
Example: a 450 sq ft room is 450 ÷ 9 = 50 square yards. At $24 per square yard the material costs $1,200. Add 10% waste and you would order 55 square yards, or $1,320.

Where square yards are used
- Carpet, often priced per square yard.
- Sod, lawn seed and landscape fabric on larger jobs.
- Paving, pavement and some flooring estimates.
Do not divide by 3: that gives a length in yards, not an area. For lengths see the feet to yards calculator. To measure the room first, use the square footage calculator, and for carpet roll planning the carpet calculator or flooring calculator.
