Rug size guide
The right rug size comes from the furniture, not the room: under a bed you want 24-36 in of rug on each side, in a living room the front legs of every seat on the rug, and under a dining table 24-36 in of rug beyond every edge. In practice that means an 8x10 for a queen bed or a typical living room, a 9x12 for a king bed or a 6-seat table, and a runner that stops 6-18 in short of each end of a hall.

| Twin bed | 24-36 in of rug on each side | 5x8 (3x5 or 4x6 against a wall) |
| Living room | Front legs of every seat on the rug | 8x10 (9x12 for an 8 ft sofa) |
| Dining room | 24-36 in of rug beyond the table | 9x12 for 6 seats |
| Entryway | At least as wide as the door | 4x6 for a 36 in door |
| Hallway | Runner 6-18 in short of each end | 2.5x12 runner for a 14 ft hall |
Every size in this chart comes from the rug size calculator, which draws your own room to scale. For the dimensions of each standard size, see standard rug sizes.
Three rules behind every rug size
- Size the rug to the furniture, not the room. A rug defines a zone: the bed, the conversation area, the dining table. It should hold that group together, so it starts from the furniture's footprint plus the space people move through.
- Leave 8-18 in of floor at the walls. The strip of bare floor frames the rug and shows it was chosen, not fitted. Less than 8 in looks like carpet that shrank.
- When two sizes work, take the larger. A rug that is too small breaks a room into pieces; a generous one makes it read as one space. The exception is a rug that would run into walls or doors.
Bedroom rug placement
Lay the rug with its long side across the bed, so it shows on both sides where your feet land. Stop the top edge just in front of the nightstands, or run it fully under them with a larger rug, so they never rock on the rug's edge. Most of the bed sits on the rug and 18-36 in extends past the foot. That is why depth matters as much as width: a rug that is wide enough but too shallow ends up floating in the middle of the bed.
Living and dining rooms
In a living room, the rug should run under the front legs of the sofa and every chair. In a dining room, it should reach far enough past the table that pulled-out chairs stay on it.
Questions people ask
How big should a rug be?
Big enough to relate to the furniture around it: 24-36 in beside a bed, under the front legs of every seat in a living room, 24-36 in past a dining table. Then check that 8-18 in of floor still shows at the walls.
How do you choose an area rug size?
Start with the furniture group the rug belongs to, not the room. Measure it, add the clearance for that room (for example 48-72 in to a dining table's length and width), and round to the nearest standard size. If two sizes both work, the larger one usually looks better.
What size rug for a bedroom?
Match it to the bed: a 5x8 for a twin, a 6x9 for a full, an 8x10 for a queen and a 9x12 for a king or California king, each laid with the long side across the bed.
What size rug for a nursery?
Put the rug where the child plays, not under the crib: a 5x8 or 6x9 in the open floor, or a 6 ft round in a smaller room. A low pile is easier to clean and safer for first steps.
