The calculator needs JavaScript; the rules and tables below give the same answers.
Standard rug sizes
Rugs are sold in a few fixed sizes. In the US: 2′ × 3′, 3′ × 5′, 4′ × 6′, 5′ × 8′, 6′ × 9′, 8′ × 10′, 9′ × 12′, 10′ × 14′ and 12′ × 15′, plus rounds of 4′ to 12′. In Europe and the UK: 60 × 90, 80 × 150, 120 × 170, 160 × 230, 170 × 240, 200 × 290, 200 × 300, 240 × 340 and 300 × 400 cm. The calculator only suggests sizes you can buy, and switches list with the units.
| Size | Where it usually goes |
|---|---|
| 2′ × 3′ · 3′ × 5′ | Doorways, beside a bed, in front of a sink |
| 4′ × 6′ · 5′ × 8′ | Under a coffee table in a small seating area, beside a twin bed |
| 6′ × 9′ | Small living rooms, under a full or queen bed at the least |
| 8′ × 10′ | The most common living-room size; under a queen or king bed; under a table for 4 to 6 |
| 9′ × 12′ · 10′ × 14′ | Large living rooms, under a king bed, under a table for 6 to 10 |
What size rug for a bed
Our rule: the rug lies across the bed, long side side to side, starting about a third of the way down the bed so the nightstands stay on bare floor. It should show at least 18 in of rug on each side and past the foot (24 in is roomier). The table gives the smallest standard size that does each.
| Bed | Mattress | Roomy (24 in) | At least (18 in) |
|---|---|---|---|
| Twin | 38 × 75 in | 10′ × 8′ | 9′ × 6′ |
| Full | 54 × 75 in | 10′ × 8′ | 9′ × 6′ |
| Queen | 60 × 80 in | 10′ × 8′ | 9′ × 6′ |
| King | 76 × 80 in | 12′ × 9′ | 10′ × 8′ |
| California king | 72 × 84 in | 10′ × 8′ | 10′ × 8′ |
Rug size for a king bed: 12′ × 9′ shows 34 in of rug each side of a 76 in king; 10′ × 8′ shows 22 in. Rug size for a queen bed: 10′ × 8′ shows 30 in each side of a 60 in queen; 9′ × 6′ shows 24 in. For a twin, a 2′ × 3′ or 3′ × 5′ rug on the side you get out of is a common, cheaper choice.
Living room rug size
A rug that fills the seating area makes a room look bigger than a small one floating in the middle. Leave 12 to 18 in of bare floor at the walls. With the sofa against a wall, its front legs then sit on the rug. The calculator picks the largest standard rug that leaves at least 12 in.
| Room | Rug |
|---|---|
| 10′ × 12′ | 8′ × 10′ |
| 11′ × 14′ | 9′ × 12′ |
| 12′ × 15′ | 9′ × 12′ |
| 13′ × 16′ | 10′ × 14′ |
| 14′ × 18′ | 12′ × 15′ |
| 16′ × 20′ | 12′ × 15′ |
Rug size under a dining table
Chairs pulled out to sit down must stay on the rug, so it runs at least 24 in past every edge of the table (30 in is roomier).
| Table | Roomy (30 in) | At least (24 in) |
|---|---|---|
| 36 × 48 in | 8′ × 10′ | 8′ × 10′ |
| 36 × 60 in | 8′ × 10′ | 8′ × 10′ |
| 38 × 72 in | 9′ × 12′ | 8′ × 10′ |
| 40 × 84 in | 9′ × 12′ | 9′ × 12′ |
| 42 × 96 in | 10′ × 14′ | 9′ × 12′ |
| 36 in round | 8′ round | 8′ round |
| 42 in round | 10′ round | 8′ round |
| 48 in round | 10′ round | 8′ round |
| 54 in round | 10′ round | 10′ round |
| 60 in round | 10′ round | 10′ round |

Should the rug go under the sofa?
In most living rooms the front legs of the sofa sit on the rug and the back legs on the floor. That needs a rug that comes within 18 in of the wall the sofa stands against.
Are these rules from a standard?
No. There is no official standard for rug sizes; these are common designer rules of thumb, stated with their numbers so you can change them. The calculator and this page use the same rules.
Is anything I type sent to you?
