How to find the right rug size
- Pick the room. Living room, bedroom, dining room or hallway, since each follows different spacing rules.
- Measure the room and furniture. Enter the room or hallway length and width, plus your sofa length, bed size, or table size and shape.
- Choose a layout. In a living room, front legs on the rug, all legs on, or a floating rug under the coffee table.
- Read the size. See the recommended standard size, the minimum that works, the floor border it leaves and a to scale plan of the rug in your room.
What decides the right rug size
A well sized rug makes a room feel pulled together, while one that is too small looks like a bath mat floating in the middle of the floor. The right size depends on three things: the room, the furniture it needs to anchor, and the border of bare floor you leave around it. The calculator combines all three, recommends a standard size you can actually buy and draws it to scale in your room.
Living room rug size guide
| Layout | How it looks | Typical size |
|---|---|---|
| All legs on | Every piece of seating sits fully on the rug | 9 x 12 ft or larger |
| Front legs on | Front legs of the sofa and chairs rest on the rug | 8 x 10 ft |
| Floating | Rug sits under the coffee table only | 5 x 8 or 6 x 9 ft |
In most living rooms, the front legs layout is the sweet spot. It connects the sofa and chairs into one conversation area without needing an oversized rug. Whatever you choose, the rug should be at least as long as your sofa, ideally with 6 inches spare at each end.
Bedroom rug size guide
Place the rug crosswise under the bottom two thirds of the bed, starting just in front of the nightstands. You want at least 18 inches of rug on each side of the bed, so the first step in the morning lands on something soft.
| Bed | Recommended rug |
|---|---|
| Twin | 5 x 8 ft |
| Full or double | 6 x 9 ft |
| Queen | 8 x 10 ft |
| King or California king | 9 x 12 ft |
In a smaller bedroom, two runners work instead of one big rug: one down each side of the bed. A 2.5 x 8 ft runner suits a queen or king, because it runs the full length of the bed (about 80 in) with a little to spare. A 2 x 6 ft runner suits a twin or full.
Dining room rug size guide
Measure your table and add 24 inches on every side. That gives chairs room to slide back without catching on the edge. A 72 by 40 inch table therefore needs a rug of at least 120 by 88 inches, which makes 8 x 10 feet the smallest standard size that works.
Round rug sizes for a round dining table
The same 24 inch rule works for a round table: add 24 inches on every side, so the rug diameter is the table diameter plus 48 inches. Pick the round option in the calculator and enter the table diameter.
| Round table | Usually seats | Minimum rug diameter | Standard round rug |
|---|---|---|---|
| 36 in | 2 to 4 | 84 in | 7 ft round |
| 42 in | 4 | 90 in | 8 ft round |
| 48 in | 4 to 6 | 96 in | 8 ft round |
| 60 in | 6 to 8 | 108 in | 9 ft round |
A square rug works just as well under a round table if you prefer straight lines; use the same size.
Hallway runner and entryway rug sizes
A runner should leave about 4 to 6 inches (10 to 15 cm) of floor on each side and stop at least 6 inches (15 cm) short of each end. Runners come in standard widths of 2, 2.5 and 3 ft (60 to 90 cm) and lengths from 6 to 14 ft, so the width of your hallway decides the width of the runner.
| Hallway width | Runner width | Floor each side |
|---|---|---|
| 36 in (3 ft) | 2 ft | 6 in |
| 42 in (3.5 ft) | 2.5 ft | 6 in |
| 48 in (4 ft) | 3 ft | 6 in |
| 110 cm | 80 cm | 15 cm |
For a hallway longer than about 18 ft, two runners of the same width with a small gap between them look better than one short runner. At a front door, choose an entryway rug at least as wide as the door opening, so a 3 x 5 ft rug for a single door and a 4 x 6 or 5 x 8 ft rug for double doors, and check that the door clears it when it swings open.
Worked examples: rug sizes for small, average and large rooms
Real results from the calculator for different rooms, in feet and in metric.
| Room | Furniture | Recommended | Floor border |
|---|---|---|---|
| Living room, 10 x 10 ft | 72 in sofa, front legs on | 5 x 8 ft | The largest standard rug with a 12 in border; a floating rug fits better |
| Living room, 12 x 10 ft | 78 in sofa, front legs on | 6 x 9 ft | 18 in at the ends, 24 in at the sides |
| Living room, 16 x 13 ft | 84 in sofa, front legs on | 8 x 10 ft | 36 in at the ends, 30 in at the sides |
| Living room, 4 x 3 m | 200 cm sofa, front legs on | 200 x 290 cm | 55 cm at the ends, 50 cm at the sides |
| Bedroom, 4 x 3.5 m | Queen bed | 200 x 290 cm | 55 cm at the ends, 75 cm at the sides |
| Bedroom, 13 x 12 ft | King bed | 8 x 10 ft | 9 x 12 ft would leave under 12 in of floor, so 8 x 10 ft is the largest that fits |
| Dining room, 16 x 13 ft | 72 x 40 in table | 8 x 10 ft | Needs at least 120 x 88 in, so chairs stay on the rug |
| Dining room, 13 x 12 ft | 48 in round table | 8 ft round | 24 in at the sides |
| Hallway, 14 x 3.5 ft | None | 2.5 x 12 ft runner | 6 in each side, 12 in at each end |
| Hallway, 4 x 1.1 m | None | 80 x 350 cm runner | 15 cm each side, 25 cm at each end |
In a 16 x 13 ft room, a 9 x 12 ft rug also works if you want all the furniture legs on the rug.
How much floor should show around a rug?
Designers usually leave 12 to 18 inches (30 to 45 cm) of bare floor between the rug and the walls. Less than that and the rug looks like wall to wall carpet that didn't quite fit; much more and it looks small. In narrow rooms, keep the border even on both long sides.
