Queen vs King Bed: Which Size Is Right for Your Bedroom?

It's the question we get asked most often at Ecofurniture: should I go with a queen or a king? The answer is rarely about the bed itself — it's about the room, the sleepers, and the small ongoing costs no one mentions in the showroom. Here's the honest version.

The Australian standard sizes, in millimetres

Bed sizes vary between countries. If you're comparing brands or reading US content, ignore it — Australian standards are their own thing.

• Queen: 1530mm × 2030mm (roughly 153cm wide × 203cm long)
• King: 1830mm × 2030mm (roughly 183cm wide × 203cm long)

The length is identical. The only difference is 30cm of extra width on a king — 15cm per sleeper. That's the whole conversation.

How much bedroom space do you actually need?

Bed size on paper is one number. Bed size in a room is a completely different one — because you also need clearance for walking around it, opening drawers, and putting bedside tables at both sides.

Queen bed — minimum room size

A queen bed with two bedside tables and 60cm of walking space on both sides needs a bedroom of at least 3.5m × 3.5m. That's the smallest we'd recommend.

King bed — minimum room size

A king with the same clearances needs at least 3.8m × 3.8m, ideally 4m × 4m. In a smaller room, you can fit a king — but you'll lose one bedside table, walk sideways to open the wardrobe, and the room will feel dominated by the bed rather than restful.

The "look" test

Beyond the walking clearance, ask: how much of the floor is bed? If the bed takes up more than about 40% of the floor's visual footprint, the room reads as cramped no matter how big it actually is. This is where a queen frame often looks better in a room that could technically fit a king.

How you sleep — the honest bit

Bed size marketing loves to talk about "extra space." What that actually translates to depends on how you and your partner sleep.

• Both sleepers stay still and cool: a queen is plenty. 76.5cm per sleeper is close to a standard single bed's width — comfortable for most adults.
• One or both are restless, hot, or tall (over 190cm): the extra 15cm each of a king pays off every night. Especially if a pet climbs on the bed too.
• Occasional co-sleeping with kids or pets: king wins convincingly. Two adults plus a small child on a queen means someone spends the night on the edge.
• Single sleepers: a queen is a treat. A king is often too big — you lose the "hug" a bed frame gives when its width is close to your own.

The ongoing costs of a king bed

This is where the queen makes a quiet case. Everything you'll buy for the bed for the rest of its life costs more in king size:

• Sheets and quilt covers: king linen typically costs 20–30% more than queen at the same quality tier. Multiply that across two sheet sets, three fitted-sheet spares, and one summer/one winter quilt cover.
• Mattress: a like-for-like king mattress runs about $200–500 more than the queen version.
• Quilt: a king quilt is a different SKU. Queen quilts don't cover a king properly — you'll have exposed corners and pull-off in the night.
• Bedside tables: not strictly more expensive, but you'll want proportionally larger ones to visually anchor a king (a small nightstand looks lost next to it).

Over five years, the "bigger is better" decision costs about $600–1,000 extra in soft furnishings alone. Worth it for the right sleepers. Not worth it if you're only doing it to use the space.

Storage and frame style

The wider footprint of a king changes the styling options too:

• Upholstered headboards feel more architectural on a king because there's more surface to become a feature.
• Under-bed storage drawers add significant capacity — a king with 4 drawers holds effectively an extra wardrobe of linen and off-season clothes.
• Simpler timber or slat-based frames read cleanly in queen size but can feel visually "thin" on a king. Choose a frame with visual weight — a plinth base, a wingback headboard, or a fabric-wrapped platform.

Browse our King Bed Frames or Queen Bed Frames — every model in the Ecofurniture range is available in both sizes so you can compare like-for-like without style compromise.

The quick decision framework

If you can only remember one thing:

Choose a queen if your bedroom is under 3.8m in either dimension, if you sleep alone, or if the room feels cramped when you walk in with the tape measure held to a king outline on the floor. Choose a king in every other case.

And a small piece of advice we give everyone: tape out the bed footprint on your bedroom floor with masking tape before you order. Walk around it, sit on the floor next to it, open your wardrobe doors. The tape doesn't lie, and it costs nothing.

The mattress question

Our own mattress range launches mid-2026 with a 7-year manufacturer's warranty. In the meantime, our bed frames are designed to fit any standard Australian queen or king mattress — pocket-spring, memory foam, or hybrid. Whatever you already own, or whatever you buy next, will fit.
