A rug can look generous in a shop and surprisingly small between your sofa and coffee table. Before choosing a pattern, decide which part of the room you want it to bring together. A few measurements and a trial outline will tell you more than a carefully styled catalogue photograph.
Start with the furniture you actually use
Draw a simple overhead plan showing the sofa, armchairs, coffee table, television unit and doors. Note the sofa width and the distance between the seats you want to connect. If a new sofa is part of the project, start with our small living-room sofa measuring guide.
Mark where people walk towards the window and doorway. Think about the room on an ordinary evening: where bags land, whether someone pulls up another chair and how you reach a side table. A rug arrangement should work with those habits.
Try two outlines on the floor
Mark the corners with paper or another material suitable for your flooring. First try an outline large enough to take the front feet of the sofa and the relevant armchairs. IKEA’s sizing guidance also uses this placement as a starting point. Treat it as an option to test, rather than a rule every room must follow.
Then mark the next available size. Sit down, stand up and walk your usual routes. Move the coffee table as you would for cleaning. Take a photograph of both arrangements from the doorway so that you compare the same view instead of two flattering angles.
Make a short shopping note
- Preferred and maximum dimensions: record length and width separately, in centimetres.
- Furniture position: decide which feet should sit on the rug.
- Doors and drawers: check their opening path and the thickness it can accommodate.
- Everyday use: include pets, children, snacks beside the sofa and busy walkways.
- Care: read the actual product instructions and consider where cleaning will happen.
Save the exact product reference. Similar-looking designs can have different fibres, backing and washing instructions. Ask whether a separate underlay is needed, whether it suits your floor and whether it is included in the price.
Choose the pattern after narrowing the size
Compare your final options with a fabric sample and a daylight photograph of the room. Check the seller’s exchange conditions if the colour looks different at home, and keep any packaging those conditions require. Ask separately about a rug cut to order; do not assume it has the same return arrangements as a standard item.
Can a large rug work in a small room?
It can, provided the trial outline fits the seating and the walking space you need. Room area alone is not enough to choose a size. The position of the furniture and the routes around it are more useful measurements.
What changes with a chaise sofa?
Draw the projecting section as well as the main seat. Test the outline against the whole shape, then look from each end of the sofa. Measuring only the backrest can overlook the part of the room used by the chaise and coffee table.
