Rug Size Calculator
Enter your room, bed or dining table below and get the rug size an interior designer would specify, with the placement rules that make a room feel finished, not the guesswork that makes it feel small.

| Room / Use | Typical Room Size | Rug Size |
|---|---|---|
| Entry, kitchen runner | — | 2'6" × 8' – 3' × 5' |
| Small seating area | Under 10' × 12' | 5' × 8' – 6' × 9' |
| Standard living room | 10' × 12' – 12' × 15' | 8' × 10' |
| Large living room | 12' × 15' – 14' × 17' | 9' × 12' |
| Great room | 15' × 18' and up | 10' × 14' – 12' × 15' |
| Bed | Classic (lower ⅔) | Full coverage |
|---|---|---|
| Twin | 5' × 8' | 6' × 9' |
| Full | 6' × 9' | 8' × 10' |
| Queen | 8' × 10' | 9' × 12' |
| King | 9' × 12' | 10' × 14' |
| California King | 9' × 12' | 10' × 14' |
| Dining Table | Table Size | Rug Size |
|---|---|---|
| 4 seats, round | 48" diameter | 8' round |
| 4–6 seats, rectangular | 36" × 60" | 8' × 10' |
| 6 seats, rectangular | 36" × 72" | 8' × 10' |
| 8 seats, rectangular | 40" × 92" | 9' × 12' |
| 10 seats, rectangular | 44" × 108" | 10' × 14' |

Most living rooms take an 8x10 or 9x12. The rule: the rug should be large enough that at least the front legs of every seating piece rest on it, with 12–18 inches of bare floor at the walls. A typical 12x15 room takes a 9x12; a 10x12 room takes an 8x10.
An 8x10, placed under the lower two-thirds of the bed so it extends about 24 inches beyond each side and the foot. Choose a 9x12 if you want the nightstands on the rug too.
A 9x12 is the standard under a king or California king, leaving 22–28 inches of rug showing per side. In a large room, a 10x14 lets the whole bed wall sit on the rug.
Add at least 24 inches (ideally 30) to every side of the table so chairs stay on the rug even when pulled out. A 6-seat 36x72 table needs an 8x10 minimum; an 8-seat table usually needs a 9x12; a 48-inch round table pairs with an 8-foot round rug.
Buying too small. A rug floating in front of the sofa with nothing touching it makes the room feel smaller and unfinished. When in doubt, size up.
