💡 How to Calculate Square Yards
Square yards measure area and are commonly used in the US for carpet, flooring, fabric, sod, and landscaping. One square yard equals a 3-foot × 3-foot area (9 square feet). See also our square footage calculator, square meters calculator, and square inches calculator.
The calculator above supports 3 shapes (rectangle, circle, triangle), accepts 4 input units (feet, inches, yards, meters), and includes cost estimation with waste factor. For volume calculations, try our square feet to cubic yards calculator.
Square Yardage Formulas
| Shape | Formula (ft) | To Sq Yd |
|---|---|---|
| Rectangle | L × W | ÷ 9 |
| Circle | π × r² | ÷ 9 |
| Triangle | ½ × base × height | ÷ 9 |
All measurements must be in the same unit. The calculator converts automatically. To convert manually: divide sq ft by 9 to get sq yd.
How to Convert Square Feet to Square Yards
Square yards = square feet ÷ 9
This is the most common conversion. Since 1 yard = 3 feet, the area conversion factor is 3² = 9.
Examples:
- 100 sq ft ÷ 9 = 11.11 sq yd
- 144 sq ft (12×12 room) ÷ 9 = 16 sq yd
- 200 sq ft ÷ 9 = 22.22 sq yd
- 500 sq ft ÷ 9 = 55.56 sq yd
- 1,000 sq ft ÷ 9 = 111.11 sq yd
Carpet & Flooring Cost per Square Yard
| Material | Cost/sq yd (installed) | Cost for 200 sq ft room |
|---|---|---|
| Builder-grade carpet | $15–$25 | $333–$556 |
| Mid-range carpet | $25–$45 | $556–$1,000 |
| Premium carpet | $45–$80 | $1,000–$1,778 |
| Indoor/outdoor carpet | $10–$20 | $222–$444 |
| Carpet padding | $3–$8 | $67–$178 |
Add 10–15% waste for seams, pattern matching, and closets. Stairways require additional yardage — typically 1 sq yd per 3 steps.
