How to lay out a 3 by 4 metre bedroom

A 3 by 4 metre bedroom is the size where a bedroom becomes a proper room again. At 12 square metres you can put a queen bed against a wall, flank it with matching nightstands, fit a real wardrobe, and still have a corner left for a small desk, provided you place the bed and its walkways first and let everything else fit around them. The extra metre of length over a 3 by 3 room is what buys the desk and the symmetry. The room above is a real 3 by 4 metre layout you can orbit and open in the editor.

Pick the bed wall

In a 3 by 4 room the bed head almost always wants the 3 metre wall, so the bed runs down the length of the room and leaves a walkway on both long sides. A 160 cm queen centred on a 3 metre wall leaves 70 cm on each side, which is the sweet spot: enough to get in from either side, make the bed, and set a nightstand without pinching the path. Putting the bed head on a 4 metre wall works too, but it usually forces the bed into a corner and kills one side's walkway, so save that for when a window or radiator blocks the short wall.

Symmetric nightstands

A centred bed on the 3 metre wall leaves room for a nightstand on each side, and matched nightstands are the cheapest way to make a bedroom look deliberate. Each one wants 40 to 50 cm of width and should not push into the 70 cm walkway. If the wall is tight, wall-mounted shelves or slim floating nightstands give you the surface without the floor footprint. Keep the tops at mattress height, roughly 60 cm, so a lamp and a glass of water sit within reach from the pillow.

The order that works

1. 01Place the bed head centred on the 3 metre wall, leaving about 70 cm of clear floor on each long side.
2. 02Add a matching nightstand on each side, 40 to 50 cm wide, without narrowing the walkway.
3. 03Put the wardrobe on a long wall where its doors clear the bed and the bedroom door, measuring the 60 cm swing first.
4. 04Fit the desk in the corner near the window, facing the wall or the glass, in the space the bed does not need.
5. 05Leave the foot of the bed open as the main cross-route, at least 70 cm to the wall or wardrobe opposite.

Fitting the wardrobe without blocking the door

The wardrobe is where a 3 by 4 room goes wrong most often, because a hinged wardrobe placed near the bedroom door turns two door swings into one collision. Map both before you place it: the bedroom door swings roughly 90 cm, the wardrobe doors another 60 cm, and they must not overlap. The clean solution is to put the wardrobe on the wall the bedroom door does not open onto, or to use a sliding-door wardrobe so there is no swing to clash at all. On a 4 metre wall a 2 metre wardrobe still leaves 2 metres for a desk or a chair.

Does a desk fit?

Usually yes, and this is the payoff of the extra metre. A small desk of 100 to 120 cm needs its top plus about 75 cm behind it for the chair to pull out and for you to sit. Tuck it into the corner by the window, where it borrows daylight and stays out of the bed's walkways. If the room is doing double duty as a home office, the desk earns its place; if it is purely for sleep, spend that corner on a reading chair instead. See the furniture dimensions guide for the desk and chair depths.

Bed sizes and their footprints

The bed you choose decides how much of the plan survives. These are the mattress footprints; add a few centimetres for the frame.
