Rug Size Calculator & Room Fit Guide

Enter the room and the furniture, and get the standard rug size that fits: 5×8, 6×9, 8×10 or 9×12 ft (or 120×180, 160×230, 200×300 cm), with the border of bare floor each layout needs.

How to choose the right rug size

The most common decorating mistake is not colour or pattern — it is a rug that is too small. A rug floating in the middle of a room makes the furniture look like it is standing around the edge waiting to be let in. The fix is one simple idea: the rug should sit under the furniture group, with enough of it showing on every side that the arrangement reads as a single piece.

Three measurements decide everything

Standard sizes, imperial and metric

2 × 3 ft60 × 90 cmDoormat, small bathroom, beside a bed
3 × 5 ft80 × 150 cmPowder room, narrow bedside, kitchen sink
4 × 6 ft120 × 180 cmSmall bedroom, home office nook, under a coffee table

Metric rugs are sold at nominal sizes rather than exact conversions: a 5 × 8 ft rug is 152 × 244 cm, while the metric size on the shelf is usually 160 × 230 cm. Both work in the same room, but measure the label before you buy — a "200 × 300" rug is 6.6 × 9.8 ft, not 6 × 9 ft.

Living room: under the coffee table

Measure the room, then subtract about 2 ft from each dimension for the rug that leaves the right border: a 12 × 14 ft room lands on an 8 × 10 ft rug. Check the sofa too. An 84 in sofa with an 8 ft rug leaves only 6 in of rug on each side, which looks accidental; 12 in past each arm looks deliberate.

Dining room: chairs pulled out

Allow 24 in (60 cm) beyond every edge of the table, 30 in (75 cm) if the room allows. A standard six-seat table (60 × 36 in) is comfortable on an 8 × 10 ft rug, which leaves 30 in beyond every edge, and generous on a 9 × 12 ft one. Round tables take round rugs: table diameter plus 48 in.

Bedroom: bed sizes

A queen bed (60 × 80 in) lands on an 8 × 10 ft rug that extends 18 in past each side and 24 in past the foot; a king (76 × 80 in) needs 9 × 12 ft; a twin or full bed is comfortable with 5 × 8 or 6 × 9 ft. In a small room, skip the large rug and put two runners down either side of the bed instead.

Runners and entryways

Runner width is the hallway width minus 12 in, and the length should stop about 12 in short of each end so doors swing clear. 2.5 × 8 ft and 2.5 × 10 ft cover most hallways; a 3 × 12 ft runner suits a long galley kitchen or a wide foyer.

Finish with the right pad

Buy a pad 1–2 in smaller than the rug: felt for hard floors, rubber or gripper for carpet. It stops the rug creeping, protects the floor finish and adds a surprising amount of comfort underfoot.

Frequently asked questions

What size rug should I put in a 12 × 14 living room?

An 8 × 10 ft (240 × 300 cm) rug. Subtracting about 2 ft of bare floor on each side gives a target of 8 × 10 ft, which lands exactly on a standard size and leaves roughly 2 ft of floor visible all the way round. If your sofa is wider than 7 ft, check that the rug still extends 6–12 in past each arm.

What size rug goes under a queen bed?

An 8 × 10 ft rug, placed so it extends about 18 in past each side of the bed and 24 in past the foot. A king bed needs 9 × 12 ft. In a small room where a large rug will not fit, two 2.5 × 8 ft runners down either side of the bed are the standard alternative.

How big should a dining room rug be?

At least 24 in (60 cm) beyond every edge of the table so chairs stay on the rug when they are pulled out — 30 in (75 cm) if space allows. A standard six-seat table measuring 60 × 36 in fits an 8 × 10 ft rug (30 in beyond every edge) or a roomier 9 × 12 ft; a round table needs a round rug whose diameter is the table diameter plus 48 in.

Should a rug go under the bed or only at the foot?

For a queen or king in a room with space, tuck the rug one third to one half of the way under the bed: it anchors the bed and gives you somewhere warm to stand. In a small room, a rug at the foot of the bed plus runners either side solves the same problem without swallowing the floor.

How much bare floor should be left around a rug?

In a living room, 18–24 in (45–60 cm) on each side is the sweet spot, and 12 in is the minimum before the rug starts to look as though it is straining towards the walls. In a dining room the clearance is set by the chairs instead, and in a hallway 6 in on each side clears the skirting board.

Do metric rug sizes match the imperial sizes exactly?

No. Metric rugs are sold at nominal sizes, so a 5 × 8 ft rug (152 × 244 cm) is usually replaced on the shelf by a 160 × 230 cm one, and a 6 × 9 ft rug by 200 × 300 cm. The difference rarely matters in a room, but it does matter when a rug has to match a precise furniture footprint — measure the label.
