Carpeting a 12 × 20 room
A 12 × 20-foot room is 240 sq ft, or 26.7 square yards (carpet is priced by the yard — divide square feet by 9). Carpet comes off a 12-ft broadloom roll, so this room takes about 20 running feet in one seamless piece.
Installed cost is three layers: the carpet itself ($933–$1,467 at standard grade), padding ($72–$360), and labor ($400–$933) — about $1,405–$2,760 all in. Grade, stairs, and tearing out old carpet move that most.
What drives your cost
| Factor | Effect on cost |
|---|---|
| Floor area | ~240 sq ft (26.7 sq yd) — carpet is priced per square yard |
| Roll width & seams | Fits a 12-ft roll with no seam |
| Carpet grade | Economy vs premium roughly doubles the material price per square yard |
| Padding / underlay | A separate per-sq-ft cost; thicker pad adds comfort and a little price |
| Installation | Labor is charged per square yard; stairs and tricky layouts cost more |
| Old carpet removal | Tear-out and haul-away of the existing floor is an add-on most quotes list separately |

Carpet buying tips
- Measure each room and closet separately — carpet is cut off a fixed-width roll, so a long thin space wastes more than its square footage suggests.
- Plan seam placement away from doorways and high-traffic paths; a good installer hides seams where you'll least see or feel them.
- Don't skimp on padding — a better pad makes cheap carpet feel plush and extends its life more than a grade bump does.
- Ask whether the quote includes old-carpet removal, furniture moving, and tack strips; those add-ons are where surprise costs hide.
