Planning a 3×4 Meter Room
3×4 m is the most searched metric room size on this site and the standard double bedroom of new-build houses across the UK, Europe, India and Australia (12 m² clears the UK's 11.5 m² double-bedroom minimum by half a square metre). It is also the typical living room of a one-bedroom flat.
At 1:1.33 the 400-cm wall is the bed wall: a 160×200-cm bed with two 45-cm bedside tables uses 250 cm and leaves 75 cm per side, or a 140-cm bed leaves 85 cm per side. The 300-cm wall opposite takes a 100-cm wardrobe and an 80-cm door with 120 cm to spare.
What this size is best used for
- 1Double bedroom with wardrobe
Bed 160×200 cm centred on the 4-m wall, bedside tables 45 cm each, 75 cm to each corner; the foot zone of 300 − 200 = 100 cm would leave only 40 cm past a 60-cm wardrobe on the opposite wall, so the wardrobe goes on a side wall beyond the bedside table.
- 2Living room for four
A 220×90-cm sofa on the 4-m wall (90 cm each side), a 100×50-cm coffee table 40 cm in front, and a 120×40-cm TV unit opposite: 90 + 40 + 50 + 40 = 220 cm of the 300-cm depth, leaving 80 cm of path.
- 3Home office for two
Two 140×70-cm desks on the 4-m wall with 40 cm between them (320 cm), and 300 − 70 = 230 cm behind the chairs for a 40-cm bookcase and a 190-cm aisle.
Double bedroom in a 3×4 m room
Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.
- Bed 160×200 cm centred on the far 400-cm wall; 120 cm remain on each side.
- A 45-cm bedside table on each side leaves 75 cm to each corner; the aisle beside each side of the bed is 120 cm, since bedside tables are only 40 cm deep.
- Wardrobe 120 cm wide and 60 cm deep on the left 300-cm wall, starting at the near corner; its doors open into the side aisle rather than the 100-cm foot zone, and it narrows that aisle from 120 to 60 cm along its own 120-cm length only.
- Door in the right 300-cm wall at the near corner, 80-cm leaf hinged toward the corner, swinging into the 100-cm foot zone; a 100×45-cm chest of drawers on the near 400-cm wall between the door's arc and the wardrobe.
Mistakes this size invites
- A 180×200-cm bed with bedside tables: 180 + 90 = 270 cm on a 400-cm wall leaves 65 cm per corner, fine, but the 100-cm foot zone then has the wardrobe doors, the room door and the chest all competing.
- The bed on the 3-m wall: 160 cm leaves 70 cm per side, and the wardrobe on that wall is impossible; the 4-m wall is the bed wall in every 3×4 m room.

Lists like this can't tell you if it actually works
"A 3-seater sofa fits" is true — until the door swing eats half a meter of wall, the radiator blocks the long wall, or the walkway to the window shrinks to 50 cm. The only way to know your layout works is to see it: draw the 3×4 m room, place real furniture at true scale, and check the flow.
That's exactly what RoomSketch3D does. Drag-and-drop true-to-scale furniture pieces into your exact room and walk through it in 3D — before you buy, move, or assemble anything.
