Single vs King Single
King Single is 14 cm wider and 16 cm longer than Standard Single — for most adults it’s the better solo choice at a similar price point. The Standard Single is best reserved for children under 12 or very constrained rooms.
Sizing
Mattress vs Bed Frame: What Size Frame Do You Need?
A bed frame is always slightly larger than its mattress. Knowing the difference prevents the most common sizing mistake — ordering a frame that looks right online but leaves visible gaps around the mattress.
Always match by name, not by measurement
A Queen mattress fits a Queen frame. The frame overhang (4–10 cm per side) is intentional — it forms the bed surround. If you measure a bare frame and compare it to a mattress spec, they will never match exactly — this is normal and by design.
Room Planning
Room Size Requirements per Bed Size
Minimum room sizes assume 60 cm clearance on both sides and the foot of the bed — enough to walk comfortably and open drawers. Ideal sizes add wardrobe and door-swing clearance.
Tape-test before you buy
Mark the bed footprint on your floor with masking tape before ordering. Include the frame dimensions (not mattress) — most people are surprised how much space the surround adds, especially with a storage or bookcase headboard frame.
International
Australian vs US vs UK Bed Sizes
Size names are shared globally but dimensions are not. This is the most common source of ordering mistakes — particularly for King, where AU and US differ by a full 10 cm in width.
IKEA sizing warning: IKEA uses non-standard dimensions across many sizes. An IKEA King bed and an Australian King mattress are not interchangeable. Always verify centimetre dimensions — do not rely on size names alone when mixing brands.
Decision Guide
How to Choose the Right Bed Size for You
The right size depends on who is sleeping, how much room is available, and how long you intend to keep the bed. Here are the four most common scenarios.
The room-first rule
Choose the largest size your room comfortably fits at the minimum clearance standard (60 cm each side + foot), then confirm your budget. Most buyers regret going too small; very few regret going too large.
Specialist
Split King and Adjustable Beds Explained
A Split King is two Long Singles side by side — not a standard size you buy as a single unit. Understanding this prevents a common ordering mistake.
Split King ordering note: You need to order a King frame plus two Long Single mattresses separately — not a single King mattress. The gap between two Long Singles (92 + 92 = 184 cm) is 1 cm narrower than a King frame, which is intentional. A split-king mattress pad bridges the centre seam.
FAQ
Frequently Asked Questions
What is the most popular bed size in Australia?
Queen (153 × 203 cm) is used by 61% of Australians, making it by far the most popular size. King is second at 21% and growing. Queen is the default recommendation for couples in standard Australian bedrooms.
What are the standard Australian bed size dimensions in cm?
Single: 92×187 cm | Long Single: 92×203 cm | King Single: 106×203 cm | Double: 137×187 cm | Queen: 153×203 cm | King: 183×203 cm | Super King: 203×203 cm. Always verify with the specific manufacturer as minor variations exist.
How wide is a King size bed in Australia?
An Australian King mattress is 183 cm wide and 203 cm long. The bed frame will be slightly larger — typically 187–190 cm wide. This is 10 cm narrower than a US King (193 cm), so US bedding will not fit correctly on an Australian King frame.
Is an Australian King the same as a US King?
No. Australian King is 183×203 cm; US King is 193×203 cm — 10 cm wider. UK King is 150×200 cm, which is closer to an Australian Double. Never use size names across countries without checking centimetre dimensions first.
What is a King Single bed and how does it differ from a standard Single?
King Single (106×203 cm) is a uniquely Australian size that is 14 cm wider and 16 cm longer than a Standard Single (92×187 cm). It is the recommended upgrade for most adults who want a solo bed — it fits in similar room footprints to a Standard Single but provides significantly more sleeping space.
What room size do I need for a Queen bed?
The minimum room size for a Queen bed with comfortable clearance (60 cm each side and the foot) is 3.2×3.8 m. The ideal room with additional wardrobe and door clearance is 3.6×4.2 m. Mark the footprint with masking tape to verify fit before ordering.
King vs Super King — is it worth the upgrade?
Super King adds 20 cm of width over King (203 vs 183 cm) and requires a minimum room of 4.0×4.5 m — significantly larger than the King minimum of 3.8×4.2 m. The upgrade is worth it for large master bedrooms or families that frequently co-sleep. Delivery logistics for Super King are also more complex — verify stairwell and doorway access before ordering.
What are Long Single beds used for?
Long Single (92×203 cm) is primarily used for two purposes: taller adults (over 185 cm) who need the extra 16 cm of length compared to a Standard Single; and Split King configurations, where two Long Singles are placed side by side in a King frame to allow independently adjustable bases for each sleeper.
