Last updated:Square Feet to Square Yards for Carpet
When ordering carpet in the US, you measure the room in square feet but compare prices in square yards. To convert square feet to square yards for carpet, divide by 9: sq yd = sq ft ÷ 9. A 12 × 12 bedroom (144 sq ft) equals 16 sq yd; with 10% waste that becomes 158 sq ft or about 18 sq yd to order.
| Room size | Sq ft | Sq yd | Sq yd + 10% waste |
|---|---|---|---|
| 10 × 10 | 100 | 11.11 | 12.22 → 13 sq yd |
| 12 × 12 | 144 | 16.00 | 17.78 → 18 sq yd |
| 12 × 15 | 180 | 20.00 | 22.22 → 23 sq yd |
| 15 × 20 | 300 | 33.33 | 36.67 → 37 sq yd |

- Carpet — often priced per sq yd in the US (even though installers measure in sq ft).
- Concrete — ready-mix is priced per cubic yard, which covers 81 sq ft at 4" thick (9 sq ft per sq yd × 9 slabs of 1" thick… just use our carpet calculator for flooring).
- Topsoil and mulch — sold by the cubic yard; multiplying by area in sq yd gives depth needed.
- Fabric & tarps — roll goods priced by sq yd.
