Quick answer: Start with your furniture measurements. For living rooms, aim to place the front legs of your seating on the rug; for dining rooms allow about 60–75 cm (24–30") beyond the table on every side; for bedrooms allow at least 45–60 cm beside the bed. Check that the size fits the room before choosing a larger rug.
It can be hard to judge rug size from a photograph. The most useful starting point is the area your furniture occupies, rather than the room dimensions alone. This guide explains what to measure and how to compare sizes before you order.
Start with the furniture
Measure the furniture group first, then check how much floor remains around it. A larger rug can bring the seating together, but it still needs to clear doors and fit comfortably within the room. Mark two possible sizes on the floor to compare them.
Living room
Three layouts work:
- All legs on — the sofa and chairs sit fully on the rug. Allow extra space beyond their legs.
- Front legs on — the front legs of the sofa and chairs rest on the rug. This often works when a full seating arrangement will not fit.
- Floating — a smaller rug sits in front of the sofa, usually beneath the coffee table. This is an option for a compact room, rather than a rule to avoid.
Typical sizes: 160 × 230 cm, 200 × 300 cm and 250 × 350 cm are useful sizes to compare. Your sofa width and seating layout will determine which fits.
Bedroom
Place a large rug beneath the lower two-thirds of the bed, leaving at least 45–60 cm (18–24") beside it and at the foot where space allows. Alternatively, use a runner on each side. Check bedside tables, wardrobe doors and the route around the bed before settling on a size.
Dining room
Measure the table, then add about 60–75 cm (24–30") on every side so chairs can stay on the rug when pulled out. Test this with your actual chairs. A table measuring 90 × 150 cm, for example, needs roughly 210 × 270 cm with 60 cm clearance; seat count alone does not tell you the right rug size.
Hallways and entryways
Measure the clear walking area and leave a visible strip of floor along both sides. About 10 cm (4") per side is a useful starting point, but wider corridors may suit more. An 80 × 300 cm runner is one size to compare. Check door clearance and use a suitable non-slip pad.
A note on shape
Rectangular rugs often suit a sofa or bed arrangement. A round rug can work beneath a round dining table: add the same chair clearance to the table diameter. In a reading nook, measure the chair and side table together rather than choosing a shape first.
Frequently asked questions
What size rug for a standard living room?
200 × 300 cm (6'7" × 9'10") is a useful size to test, but there is no single standard room layout. Check that the rug is wide enough for your sofa and supports the seating legs you want on it.
Should a rug go under the bed?
It can. Leave at least 45–60 cm beyond the sides and foot where space allows, so you have rug underfoot when getting up. Runners on either side are useful when one large rug does not fit.
Is it better to have a rug too big or too small?
Choose the size that fits the furniture and leaves safe clearance around doors and walkways. If both sizes fit, the larger one may bring more of the seating onto the rug. Neither should be chosen without measuring.
How much floor should show around a rug?
A border of roughly 20–45 cm (8–18") is a useful starting point for an area rug. Adjust it for the room, furniture and walkways; it does not need to be identical on every side.
Tip: tape out the size on your floor before buying so you can see it in the space.
