ChartStandard dimensions — nothing to enter.
An 8 × 10 ft rug suits a queen bedroom and a 9 × 12 suits a king. But the bed is only half of it: what decides the size is which of the three placements your room can take. All three are below.
| Bed | Under the whole bed | From below the nightstands | Runners either side |
|---|---|---|---|
| Twin (38 × 75 in) | 5 × 8 ft | 4 × 6 ft | Two 2.5 × 8 ft |
| Full (54 × 75 in) | 8 × 10 ft | 6 × 9 ft | Two 2.5 × 8 ft |
| Queen (60 × 80 in) | 8 × 10 ft | 6 × 9 ft | Two 2.5 × 8 ft |
| King (76 × 80 in) | 9 × 12 ft | 8 × 10 ft | Two 3 × 8 ft |
| California King (72 × 84 in) | 9 × 12 ft | 8 × 10 ft | Two 3 × 8 ft |
Sized to show at least 18 in of rug at each side and past the foot, and to leave at least 6 in of floor between the rug and every wall. Enter your own room on the king and queen pages to check it fits.
The rug exists so you step onto it. That single fact settles the size: it has to show at least 18 inches at each side of the bed and past the foot, because that is where your feet land. Bed width + 36 in is the rug width you need.
Three placements, and smaller is not worse. Under the whole bed looks the most finished. From below the nightstands uses one size down and leaves the head of the bed on bare floor, which is a deliberate look, not a compromise. Runners either side cover exactly where you step out for a fraction of the money.
Leave 6 inches of floor at every wall. Closer than that and the rug runs under the wardrobe, reads as fitted carpet and catches the door.
What does not work. A small rug floating at the foot of the bed touching nothing. It makes the room look smaller and it is the most common bedroom rug mistake.
Check your room, not just your bed. A king in a small room cannot take a 9 × 12 — the calculators on the king and queen pages tell you which dimension runs out.
8 × 10 ft for a queen, 9 × 12 for a king, 5 × 8 for a twin — if the rug goes under the whole bed and the room is big enough to leave floor at the walls.
It looks the most finished, but starting the rug below the nightstands is a proper placement in its own right and uses a size smaller. In a normal bedroom it is the usual choice.
At least 18 inches. That is what you step onto, and below about 12 inches the rug stops doing its job.
Two runners either side of the bed. A rug that runs within six inches of the walls reads as fitted carpet, and at that point runners are genuinely better rather than second best.
Yes, running across the foot, and it works if the rug is at least as wide as the bed. What does not work is a small rug floating in the middle of the floor touching nothing.
Either way. Under them needs the larger rug and looks more deliberate; starting just below them saves a size and is what most rooms end up with.
