Recommended Carpet Size According to Room Type
A practical rule for finding the right size: subtract a certain amount of space from each side of your room measurement . The amount of space left will vary depending on the room's use. Therefore, the same square meter value may correspond to different aspect ratios in different room types: a 6 square meter rug is usually preferred in a 200x300 cm size in the living room and a 240x250 cm size in the dining room.
| Room type | margin | From where | Frequently preferred size |
|---|---|---|---|
| Lounge | ~35 cm | At least the front legs of the furniture should remain on the carpet. | 200x300 cm |
| Dining room | ~25 cm | When chairs are pulled out, their legs should still be on the carpet. | 200x300 · 240x340 cm |
| Bedroom | ~45 cm | Your feet should touch the carpet when you get out of bed. | 160x230 · 200x300 cm |
| Entrance / corridor | ~15 cm | The transition area is preferably in the form of a runner. | 80x150 · 80x300 cm |
If you know the dimensions of your dining room table, you can double-check: add +65 cm to each side of the table measurement ; this will ensure the chairs remain on the rug even when pulled out.
How to Measure a Carpet?
- Measure the length and width of the room in a meter.
- Calculate the carpet size so that you leave at least 30-40 cm of space from each wall.
- Draw the location of your seating arrangement on the sketch.
- Determine the area the carpet needs to cover.
- Convert the resulting area to square meters: width (cm) × height (cm) ÷ 10,000.
- Match with standard carpet sizes (see square meter chart above).
Common Measurement Errors
- Too small rug: A rug that sits only in the middle of the seating area like an "island" makes the room look cluttered.
- Carpet touching the wall: If the carpet is large enough to touch the wall, the space becomes cramped and the carpet curls against the wall.
- Wrong proportions: Using a square rug in a very long and narrow room will disrupt the balance.
- Color illusion: Light-colored carpets make a space look larger, while dark colors make it look smaller; consider color as well as size.
Practical Test
Before making a decision, trace the measurements of the rug you envision on the floor with masking tape. Live there for a few days; see for yourself if the measurements really fit. This simple method significantly reduces the risk of making the wrong choice.
