To convert square feet (ft²) to square yards (yd²), use this basic area rule: 1 yard = 3 feet, so 1 square yard = 3 ft × 3 ft = 9 square feet.
Example:
Quick tip for projects:
If you also need volume (like concrete), convert the area to yd², then multiply by thickness in yards.
Divide the square feet value by 9. One square yard equals 9 square feet, so the conversion is direct.
Formula: square yards = square feet ÷ 9
Example: 180 sq ft ÷ 9 = 20 sq yd
For quick checks, 9 sq ft always equals 1 sq yd.
The conversion factor is 1/9.
Both give the same result.
Multiply the square yards value by 9.
Formula: square feet = square yards × 9
Example: 12 sq yd × 9 = 108 sq ft
A yard is 3 feet. Area uses squared units, so you square the length change:
That’s why square feet convert to square yards by dividing by 9.
First find the room area in square feet. Then divide by 9 to get square yards.
Example: A 12 ft by 15 ft room is 180 sq ft.
180 ÷ 9 = 20 sq yd.
This helps when pricing carpet, turf, or flooring sold by the square yard.
500 ÷ 9 = 55.5556 sq yd
Rounded:
1,000 ÷ 9 = 111.1111 sq yd

Many materials need extra for cuts and waste. Rounding up can prevent shortages. A common buffer is 5% to 15%, based on the job.
If you must buy whole square yards, round up to the next full number.
Use these shortcuts:
Example estimate: 225 sq ft
225 ÷ 10 = 22.5, add 11% (about 2.5) = about 25 sq yd (exact is 25).
Both measure area, but the unit size is different:
Because of that, 1 sq yd covers 9 times more area than 1 sq ft.
Yes, the conversion is exact because it uses a fixed ratio: 1 sq yd = 9 sq ft.
Decimals only appear when the square feet number is not a multiple of 9.
If you need clean numbers, keep extra decimal places until the final step.
