Rug size guide: what size rug for your living room, bedroom and dining room

Standard rug sizes

Rugs come in a handful of standard sizes in the US, quoted in feet, width first. Actual dimensions vary by a few inches between makers, so check the exact measurements before you buy. Here are the common sizes and where each typically works.

The most common mistake is buying too small. A rug that only reaches the coffee table makes the furniture look like it's floating and the room look smaller. When you're torn between two sizes, the larger one is usually right, provided you keep the border described below.

Three living room layouts

How much of your furniture sits on the rug decides the size. There are three standard approaches.

All legs on

Every leg of the sofa, armchairs and coffee table sits on the rug. This defines the seating area most clearly and feels the most generous, but it needs a big rug: usually 9x12 or 10x14 in a typical living room. Allow the rug to extend at least 6 to 8 in beyond the sides of the sofa so it doesn't look cropped. It works especially well in open-plan spaces, where the rug acts as a room within the room.

Front legs on

The front legs of the sofa and chairs sit on the rug and the back legs sit on the floor. This is the most versatile layout and the one most living rooms use. An 8x10 usually does it in front of a standard three-seat sofa; a 9x12 does it with a longer sofa or a sofa plus two chairs. Aim for the rug to tuck at least 4 to 6 in under the front of the seating so the legs sit securely and the rug doesn't creep.

Floating

No furniture sits on the rug except the coffee table. This only works with a smaller seating group, in a small room, or where the rug is meant as an accent piece. Even then the rug should be wider than the coffee table by a good margin and roughly as long as the sofa or a little shorter; a 5x8 in front of a loveseat is a typical case. If the rug looks like a bath mat, it is too small.

Leave 8 to 24 inches of floor around the edge

A room-sized rug still shouldn't run wall to wall. Leave a border of exposed floor between the rug and the walls: 8 to 24 in, with 12 to 18 in suiting most living rooms. The border frames the rug and keeps it from looking like fitted carpet.

• Small rooms: 8 to 12 in of border is fine and lets you use the largest rug that fits.
• Average rooms: 12 to 18 in.
• Large rooms: up to 24 in, or treat the rug as a zone for the seating group rather than for the whole room.

To find your maximum rug size, measure the room and subtract twice the border from each dimension. A 12 x 15 ft room with an 18 in border can take a rug up to 9 x 12 ft. A 10 x 12 ft room with a 12 in border can take an 8 x 10 ft rug.

In open-plan rooms, size the rug to the seating group, not the room. Doors are the other limit: make sure doors can swing over the rug, especially with thick pile.

Living room rug size by seating

A quick way to choose is to start from the seating you have.

A rug should usually be wider than the sofa is long, or at least as long, so that the sofa sits within the rug's width. If the sofa extends beyond the rug at both ends, size up. With a sectional, the rug should reach into the corner of the L with the front legs of both sides on it.

Once the rug is sized, the coffee table should sit roughly centered on it. Our coffee table size guide covers how big that table should be, and the living room layout guide covers spacing.

Bedroom rug sizes by bed

Under a bed, the goal is soft floor where your feet land when you get up. Most people place the rug so it starts a little in front of the nightstands, leaving the nightstands on bare floor, and extends beyond the foot of the bed. Aim for 18 to 24 in of rug showing on each side of the bed and at least that much at the foot. A queen bed is 60 in wide, so an 8 ft (96 in) wide rug leaves about 18 in on each side.

Runners on either side of the bed are a good option when a large rug won't fit or when you want to show off a floor. Run them the length of the bed or close to it. A substantial headboard bed such as the Sipario benefits from a generous rug that balances its height. For the bed itself, see our bed size guide.

Dining room rugs: the table plus 24 inches

Under a dining table the rug has one job: keeping all four chair legs on it, even when someone pushes back to stand. That means extending the rug at least 24 in beyond the table edge on every side. Some people prefer 30 in or more if their chairs are large or roll back a long way.

The calculation is simple: add 48 in (24 in per side) to the table's length and width, then round up to the next standard size.

Match the rug's shape to the table: round under round, rectangle under rectangle. With an extending table, size the rug to the table at its usual length, or to its extended length if you open it often. A pedestal table such as the Desco sits especially well on a round rug because there are no legs to compete with the chairs. Flat weaves and low pile let chairs slide easily and are easier to clean under a table. More on table sizes in our dining table size guide.

Pile, material and practical choices

Pile height matters as much as size in some rooms. Low pile and flat weaves suit dining rooms, entries and homes with pets or robot vacuums. Medium and high pile suit living rooms and bedrooms, where they feel soft underfoot. Very high pile can make chairs wobble and may catch on doors.

Wool is a common choice for living rooms and bedrooms because it is durable, naturally resilient and feels warm. Hand-tufted wool rugs such as the Cerchi Rug pair a dense, soft surface with a defined pattern. Use a rug pad under any rug on a hard floor: it keeps the rug from sliding, cushions it and protects the floor.

Before you order, outline the rug with painter's tape and check it against the furniture and doors. Browse rugs and accessories, or ask our interior design service to size a rug for your room.
