3 × 3 m bedroom layout
A 3 × 3 m bedroom is 97 sq ft (9.00 m²), with 12.00 m (39' 4") of wall around it. Everything below is worked out from those dimensions rather than written for a room in general — the plan is to scale, and the furniture is measured against the real walls.

Planning a bedroom
A bedroom is planned around one object. The bed goes in first, and everything else — wardrobe, drawers, a chair nobody sits on — works around whatever floor is left. That is why two rooms with the same floor area can feel completely different: a long, narrow room can swallow a king bed and leave a usable walkway, while a squarer room of the same area leaves you shuffling sideways past the footboard. The numbers that matter are the width of the wall the bed stands against, the clear space down each side, and whether a wardrobe door can open fully without hitting the mattress. Get those three right and the room works; get them wrong and no amount of clever storage rescues it.
A single or small double bedroom
At this size the bed decides everything else. A double will physically fit, but it eats the room: put it against the longest wall, accept that only one side has a proper walkway, and use the other side for a slim bedside table rather than trying to keep a full 700 mm gap on both sides. A single bed changes the room completely — it frees a whole wall for a wardrobe and a desk, which is why box rooms usually work better as single or guest rooms than as compromised doubles. Keep storage tall rather than wide: a 1000 mm double wardrobe up to ceiling height stores more than a 1500 mm one at standard height and takes 500 mm less wall. Avoid anything that needs floor space to open into — sliding or bi-fold wardrobe doors are worth the extra cost here, because a hinged door needs 600 mm of clear floor that this room does not have to spare.
What fits in a 3x3 m bedroom
Each piece is measured into a furnished room, not an empty one: it needs its own width plus enough clearance to get past it along the wall, its depth plus that clearance out into the room, and it is checked with a 600 mm wardrobe on the opposite wall already in place. Both pairs of walls are tried, so a long wall counts either way round. Tight means the piece is physically in the room but the clearance is not — you are edging round it.

Clearances that decide the layout
- Beside a bed700 mm
- Enough to walk down and to make the bed from that side. 500 mm is passable but you will catch your shins.
- In front of a wardrobe900 mm
- A hinged door needs its own 600 mm arc, plus somewhere for you to stand while it is open.
- In front of a chest of drawers750 mm
- A drawer pulls out around 450 mm, and you need to stand behind it.
- At the foot of the bed600 mm
- The minimum walkway between the footboard and anything on the opposite wall.
Materials for a 3x3 m bedroom
Quantities from the real floor and wall areas, with the waste allowance already added. Estimates to plan with — measure again before you order.
| Flooring | With waste | Boxes |
|---|---|---|
| Laminate2.22 m² a box, 10% waste | 9.9 m² | 5 |
| Engineered wood1.8 m² a box, 10% waste | 9.9 m² | 6 |
| Vinyl tile (LVT)3.34 m² a box, 10% waste | 9.9 m² | 3 |
| Ceramic tile1.44 m² a box, 15% waste | 10.3 m² | 8 |
- Paint — about 5 litres for two coats on 25.4 m² of wall, at a 2.4 m ceiling with a door and a window deducted.
- Skirting — 11.17 m once one doorway is taken out of the perimeter.
- Ceiling — the same 9.00 m² as the floor, so roughly 2 litres for two coats.

Common questions
- How big is a 3x3 m bedroom?
- 97 sq ft (9.00 m²), with a perimeter of 12.00 m (39' 4"). The walls are 3.00 m (9' 10") and 3.00 m (9' 10").
- How much flooring does a 3x3 m bedroom need?
- 9.9 m² including a 10% waste allowance, which is 5 boxes of laminate at 2.22 m² a box. Tile and engineered wood come in different box sizes, so check the pack before ordering.
- How much paint does a 3x3 m bedroom need?
- About 5 litres for two coats on the walls, based on a 2.4 m ceiling, 25.4 m² of wall after a door and a window are deducted, and 12 m² of coverage per litre.
- Will a double wardrobe fit in a 3x3 m bedroom?
- Yes. It needs 1.90 m of wall and 2.10 m out into the room once its clearance is counted, and this room gives you 0.90 m to spare on top of that.
- How much space do you need around a bed?
- Allow 700 mm down each side you use, and 600 mm at the foot if there is anything to walk past. You can drop one side to 300 mm if that side is only there for access to a window, but never both — a bed you can only reach from one side is very hard to make.
- Should the bed go against the long wall or the short wall?
- Usually the short wall, so the long walls stay free for wardrobes and so the walkways run the length of the room. Change your mind if the short wall holds the window or the door swing, because neither should be blocked by a headboard.
- How deep is a wardrobe?
- 600 mm is the standard depth, and it is not arbitrary: a clothes hanger is about 450 mm across, so anything shallower than 550 mm forces the rail to run front-to-back rather than side-to-side and roughly halves what you can hang.
- Does a bedroom need space for a door swing?
- Yes, and it is the clearance most often forgotten. A standard 762 mm internal door sweeps an arc about 900 mm deep into the room. Nothing taller than the handle should sit inside that arc, which rules out putting a wardrobe on the wall the door opens against.
