Planning a 3×5 Meter Room
3×5 m is the living room of a European one-bedroom apartment, the master bedroom of a 1970s Australian brick veneer, and the through-kitchen-diner of a small British terrace. Fifteen square metres is a generous bedroom or a modest sitting room.
At 1:1.67 the 500-cm length lets a 3-m room zone end to end: a 200-cm bed zone plus a 300-cm dressing or working zone, or a sofa group plus a small table. The 300-cm width limits face-to-face seating to sofa, coffee table and TV unit with an 80-cm path.
What this size is best used for
- 1Bedroom with a dressing end
Bed 160×200 cm on the 3-m wall (70 cm per side), a 90-cm walkway, then 60-cm wardrobes on both long walls for 120 cm (300 − 120 = 180 cm between them), and 500 − 200 − 90 − 120 = 90 cm at the near end for the door.
- 2Living room with a dining corner
Sofa (220 cm) on the 5-m wall at the far end and an 80×80-cm table with two chairs at the near end: 220 + 80 = 300 cm of 500, leaving 200 cm between them for pulled-out chairs (45 cm) and a path.
- 3Kitchen-diner
Units along one long wall for 300 cm starting at the far end, and a 120×80-cm table on the opposite wall at the near end, with 300 − 60 − 80 = 160 cm between counter edge and table for chairs and passage.
Bedroom with a dressing end in a 3×5 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 300-cm wall with 45-cm bedside tables each side and 25 cm to the corners.
- The foot of the bed is 200 cm from the far wall; keep a 90-cm walkway, so wardrobes start at 290 cm.
- Wardrobes 60 cm deep and 120 cm wide on both long walls from 290 to 410 cm, facing each other across 300 − 120 = 180 cm of dressing space.
- Door in the near 300-cm wall, 80-cm leaf hinged at the right corner, swinging into the 500 − 410 = 90 cm beyond the wardrobes; a full-length mirror on the near wall's left half.
Mistakes this size invites
- Bed on the 5-m wall: 170 cm per side is lavish, but 300 − 200 = 100 cm at the foot means the wardrobes across the room leave 40 cm to pass.
- Wardrobes on one side only, 120 cm deep to make up for it: no wardrobe is 120 cm deep, and 60 cm on one side wastes the 180-cm dressing width that two facing runs create.

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 3×5 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.
