Quick answer: Standard Australian bed sizes (mattress dimensions) are: Single 92 × 188 cm, King Single 107 × 203 cm, Double 138 × 188 cm, Queen 153 × 203 cm, King 183 × 203 cm, and Super King 204 × 204 cm. Olympic Queen — a less common but roomier size — is 168 × 203 cm. Bed frames sit slightly larger than the mattress, so always check the frame's external dimensions before buying.

Note: these are standard mattress sizes. Individual mattresses and frames can vary by 1–2 cm between brands. Bed frame external footprints are larger than the mattress.
Bed frame size vs mattress size: why they differ
A bed frame is always larger than the mattress it holds. The frame's rails, headboard and (on storage beds) the surrounding structure add to the footprint — typically 5–15 cm on each side depending on the design. When you're measuring your room, plan around the frame's external dimensions, not the mattress size. Every Proferlo bed frame lists its exact external width, length and height on the product page.
How to choose the right bed size for your room
Leave at least 60 cm of walking space on each side of the bed and at the foot where possible. As a rough guide:
- Room under 3 × 3 m: Double or Queen is usually the sensible ceiling.
- Room 3 × 3.5 m or larger: Queen or King comfortably fits with bedside tables.
- Master suites 4 m+ wide: King or Super King.
If you're tight on floor space, a storage bed frame reclaims the space under the mattress for drawers — often a smarter move than sizing down.
What about the Olympic Queen?
The Olympic Queen is 15 cm wider than a standard Queen (168 cm vs 153 cm) while keeping the same 203 cm length. It's the ideal middle ground for couples who find a Queen a little tight but don't have room for a full King. Because it's a less common size, always pair it with a frame and bedding designed for it — like our Olympic Queen bedroom & mattress sets.
Frequently asked questions
What is the most popular bed size in Australia?
The Queen (153 × 203 cm) is the most popular bed size in Australia. It comfortably fits most couples while leaving room for bedside tables in a standard master bedroom.
What size is a Queen bed in Australia in cm?
A standard Australian Queen mattress is 153 cm wide and 203 cm long. The bed frame footprint is larger, so check the frame's external dimensions when measuring your room.
Is an Australian Queen the same as a US Queen?
Almost — both are about 153 × 203 cm (60 × 80 inches). They are effectively interchangeable, but bedding is sold to local standards, so buy sheets labelled for the Australian market.
What is an Olympic Queen bed?
An Olympic Queen is 168 × 203 cm — 15 cm wider than a standard Queen but the same length. It suits couples who want more width without moving up to a King.
How much bigger is a King than a Queen?
An Australian King (183 × 203 cm) is 30 cm wider than a Queen (153 × 203 cm). The length is the same, so the extra space is all width.
