What Size Rug Do I Need? The Quick Answer for Every Room

If you have ever unrolled a new rug and watched it shrink into the middle of the room, you are in good company. Size is the most common rug mistake in British homes, and it is almost always the same one: too small. So, what size rug do I need? The honest answer depends on the room and the furniture, but the rules are simpler than you might think. Below you will find the quick answer for every room, with measurements in centimetres, followed by the tape-measure tricks that take the guesswork out.

The golden rule of rug sizes

A rug should connect furniture, not float between it. In most rooms that means the rug sits under at least the front legs of the main pieces, with a border of bare floor showing around the edges. Aim for roughly 20–45 cm of floor between the rug and the walls in a typical room, a little less in a very small one. When you are torn between two rug sizes, the larger one is nearly always the better choice.

Living room: what size rug do I need?

Measure the length of your sofa and add 15–20 cm on each side. That is the minimum width of the rug.

• Small terrace or flat (two-seater sofa): 155×230 cm or 160×230 cm, with front sofa legs on the rug.
• Average living room (three-seater plus chair): 200×290 cm or 200×300 cm, so all front legs rest on it.
• Very small snug: 120×180 cm in front of the sofa, centred on the coffee table.

Avoid a rug that only fits under the coffee table; it makes the room feel disjointed.

Bedroom rug sizes

Bedroom rugs should give you something soft to step onto on both sides of the bed.

• Double bed: a 160×230 cm rug placed sideways under the lower two-thirds of the bed, leaving the bedside tables on bare floor.
• King or super king: 200×300 cm, extending around 60 cm on each side.
• Small room or single bed: an 80×150 cm rug on the side you get up, or a pair either side.
• Runners: an 80×300 cm runner along each side of the bed is a neat alternative in tight rooms.

Dining room and kitchen

Dining rugs need to be generous so chairs stay on the rug when pulled out. Measure your table and add 60 cm on every side. A typical six-seater needs a rug of around 200×300 cm; a small four-seater may suit a 160×230 cm rug if chairs tuck in neatly. For round tables, a 160 cm round suits a small bistro table, while a 200 cm round works for a table of about 90–100 cm with chairs that tuck in.

In kitchens, a 60×100 cm rug at the sink or an 80×300 cm runner along a galley is usually ideal. Our kitchen rugs include washable options.

Hallways, landings and entrances

Leave 10–15 cm of floor visible on each side of a hallway runner, and around 15–30 cm at each end. Most British hallways suit an 80×300 cm runner; wider Victorian halls can take 100×300 cm. At the front door, a 60×100 cm rug or 80×150 cm rug catches dirt while still letting the door swing clear. Browse hallway runners for options.

How to measure and test before you buy

1. Measure the room and note doors, radiators and fireplaces.
2. Decide which furniture the rug should connect.
3. Mark the rug outline on the floor with masking tape or newspaper.
4. Live with it for a day: walk around it, open doors, pull out chairs.
5. Check our full rug size guide for more layouts.

It takes ten minutes and prevents almost every sizing regret.

Frequently asked questions

What is the most popular rug size in the UK?

For living rooms, sizes around 160×230 cm and 200×290 cm are common choices because they suit typical sofa layouts. Always measure your own room first.

Is there a rug size guide UK shoppers can use?

Yes. Our rug size guide lists room-by-room layouts in centimetres, and the masking-tape test above lets you check the size in your own space.

Should a rug go under the sofa?

Ideally the front legs should sit on the rug. This links the furniture and makes the room feel larger and more cohesive.

Once you know the rules, choosing takes minutes. Next time you find yourself asking what size rug do I need, measure, mark it out with tape, and if in doubt, go one size up.
