Plan a room

Long narrow living room layout: keep the route clear

Map the route between doors first, then fit the seating beside it. In a narrow room, add furniture depths and the gaps between them across the short dimension before deciding whether the arrangement works.

Example width budget: 900 + 450 + 500 + 850 + 300 = 3000 mm. Empty bands illustrate the two gaps, not recommended minimums.

Treat the short dimension as a budget

A long room can have plenty of area but very little width where people pass. Start with the clear inside width after radiators, fireplace projections and fixed cabinetry. Then account for every object across that width.

For an assumed 3000 mm-wide room, the following arrangement uses the entire width. The gaps are scenario assumptions for comparison, not prescribed clearances. Test them with the actual furniture and the people using the room.

Part across the roomAssumed depth or gap
Sofa900 mm
Sofa-to-table gap450 mm
Coffee table500 mm
Walking route850 mm
Media unit300 mm
Total3000 mm

Choose which side carries through traffic

If the doors line up along one side, put the main route on that side rather than routing everyone between the sofa and coffee table. If an entry opens into the middle of the long wall, test two smaller zones so the entry does not cut a conversation group in half.

Check the TV and seating relationship separately. This example establishes whether the objects and route can fit across the room; it does not calculate the right viewing distance for your screen or guarantee a comfortable viewing angle.

Draw and review the bottlenecks

FloorDraft can help reveal overlapping furniture, but a collision-free outline is not a complete movement check. Inspect the route while chairs are pulled out and doors are open, then confirm it in the room.

  1. Draw the room and the openings at measured positions.
  2. Place the sofa and media unit at their real depths.
  3. Add the table, then annotate the remaining gaps.
  4. Follow the route from entry to the next door, including turns and door swings.
  5. Compare a second arrangement using the same furniture dimensions.

Questions

Should every piece go against a wall?

No. Floating a piece may help define a zone, but only if the remaining route works. Decide from the measured width and openings.

Does a smaller coffee table solve every narrow room?

It can recover width in the seating zone. It will not solve an entry door that collides with the sofa or a blocked route at the far end.
