The formula
Square yards = (Length ft × Width ft × Quantity) ÷ 9
Example: A 15 ft × 12 ft room = 180 ft² ÷ 9 = 20 yd².
How it works
- 1Multiply length × width to get the area in square feet.
- 2Multiply by the number of identical areas.
- 3Divide by 9 to convert square feet to square yards (a yard is 3 ft, so a square yard is 9 ft²).
- 4Optionally add a waste allowance for pattern matching and cuts — off by default.
