Carpet is sold by the square yard in the US. To convert:
A 12×12 ft room = 144 sq ft = 16 sq yds
Carpet comes in fixed widths (12' or 15'). You buy by linear foot.
| Room Width | 12' Roll | 15' Roll |
|---|---|---|
| Up to 12' | No seam | No seam |
| 12'-15' | 1 seam | No seam |
| 15'-24' | 1 seam | 1 seam |
| 24'-30' | 2 seams | 1 seam |
| Pad Type | Density | Price | Best For |
|---|---|---|---|
| Rebond Standard | 6-8 lb | $3-4/sq yd | General use, most rooms |
| Rebond Premium | 8-10 lb | $5-7/sq yd | Living areas, better comfort |
| Memory Foam | N/A | $8-12/sq yd | Bedrooms, luxury feel |
| Fiber Pad | Variable | $4-6/sq yd | Berber/loop pile carpet |
| Rubber | 40+ oz | $10-15/sq yd | Commercial, stairs, durability |
Tip: Don't go too thick! Pad over 7/16" can cause premature carpet wear and void warranties. Check your carpet warranty for pad requirements.
Plan for 10-15% extra for waste due to room shape and seam placement. The calculator accounts for roll width which often results in some waste.
15-foot is better for rooms over 12 feet wide as it eliminates seams. However, 15-foot has less selection and may create more waste in smaller rooms.
DIY is possible for small rooms without seams. You'll need a knee kicker, carpet stretcher, and seaming iron. Professional installation is recommended for larger jobs or rooms with seams.
Quality carpet with good pad lasts 10-15 years in moderate traffic. Heavy traffic areas may need replacement in 5-8 years. Wool and high-density nylon last longest.
Yes, the room should be cleared. Some installers will move furniture for an additional fee. Large/heavy items like pianos may require specialty movers.
