Most small living rooms feel tight for one reason: the furniture is the right size, but the gaps between it are not. You can fit a full sofa, a coffee table, and a media unit into 12 square metres and still walk through comfortably, as long as you plan the empty space first and the furniture second. The room above is a real 3 by 4 metre layout you can orbit and open in the editor.
Start with the walkways, not the sofa
Before you place a single piece, mark the paths people actually walk: door to sofa, sofa to window, room to hallway. Those paths need roughly 60 to 90 cm of clear width. Furniture fills whatever is left. When you plan in this order the layout tells you how much sofa the room can take, instead of you guessing and shuffling.
The order that works
- 01Anchor the sofa against the longest uninterrupted wall. In a small room the sofa is the biggest object, so it sets everything else.
- 02Place the coffee table 40 to 45 cm from the sofa. Close enough to reach a mug, far enough to walk past.
- 03Put the TV or media unit on the wall the sofa faces, at seated eye level. Measure the viewing distance before you buy the screen, not after.
- 04Add one accent chair only if a clear walkway survives around it. If it blocks a path, it becomes the thing everyone bumps.
- 05Lay a rug that sits under at least the front legs of the sofa. A rug that floats in the middle makes the room read smaller.
Clearances for a 3 by 4 metre room
These are the numbers the live layout above respects. Treat them as minimums, not targets, and the room stays walkable.
| Gap | Minimum | Comfortable |
|---|---|---|
| Main walkway width | 75 cm | 90 cm |
| Sofa to coffee table | 40 cm | 45 cm |
| Coffee table to TV unit | 60 cm | 90 cm |
| Seat to TV (per 10 cm screen) | 1.5 m | 2 m |
| Clear space in front of a door | 60 cm | 90 cm |
For the pieces themselves, a two-seat sofa runs about 1.6 m wide and a three-seat about 2.1 m. The full set of numbers is in the furniture dimensions guide, and the sofa specifically in standard sofa dimensions.
Common small-room mistakes
- Pushing every piece against a wall. In a small room it reads as a waiting area. Floating the sofa 10 cm off the wall often looks intentional instead of cramped.
- A coffee table the size of the sofa. Scale it down, or swap for two small nesting tables you can pull apart.
- Buying the TV before measuring the viewing distance. An oversized screen forces you to sit too close in a room that has no room to move back.
- A rug that is too small. Under the front legs is the floor; fully under the seating group is better.
