Australian bed sizes are NOT the same as US or UK sizes. A US King (193 cm wide) is 10 cm wider than an Australian King (183 cm). A UK King (150 × 200 cm) is closer in size to an Australian Queen. Always check centimetre dimensions when ordering internationally.
Single Bed Size
92 × 188 cm · 36″ × 74″ · $400–$750
The standard single bed size in Australia measures 92 × 188 cm. It's the most space-efficient option and works well for children's rooms, small guest rooms, and bunk beds. About 3% of Australian adults sleep on a single mattress nightly — for most adults, the King Single is a better fit.
- Minimum room size: 2.5 m × 3.0 m
- Ideal room size: 3.0 m × 3.5 m
- Also known as a 'twin' in the US — though US twin dimensions differ slightly (97 × 191 cm)
- Used in bunk beds, trundle beds, and children's first beds
- Not recommended for adults over 185 cm tall — consider King Single or Long Single

Long Single Bed Size
92 × 203 cm · 36″ × 80″ · $500–$1,000
The long single is the same width as a standard single (92 cm) but 15 cm longer at 203 cm. Its most important use: two long singles placed side by side create a split king — the exact dimensions of a standard Australian King (183 × 203 cm). This makes long singles the mattress of choice for adjustable split king bed bases.
- Minimum room size: 2.6 m × 3.2 m
- Primary use: split king / adjustable base setups
- Also suits adults over 185 cm with limited room width
- Bedding is specialty — look for 'long single' labelled sheets
- Split king bedding: 1 King flat sheet + 2 Long Single fitted sheets + 2 pillowcases
Two long singles (92 × 203 cm each) = one standard King (183 × 203 cm). Each side can have a different mattress firmness — ideal for couples with different sleep preferences or adjustable base users.
King Single Bed Size
107 × 203 cm · 42″ × 80″ · $500–$1,000
The king single bed size is a uniquely Australian mattress size. At 107 × 203 cm, it is 15 cm wider and 15 cm longer than a standard single — a meaningful upgrade for teenagers, taller adults, and anyone who wants more sleeping room without taking up the space of a double.
- About 3% of Australian adults sleep on a king single nightly
- Also common in mine site and FIFO accommodation
- Minimum room size: 2.6 m × 3.2 m
- King single bedding is labelled separately — standard single sheets will not fit
- Does NOT exist in the US or UK — uniquely Australian
- Not to be confused with Long Single (92 cm wide) — King Single is the wider one (107 cm)
King Single vs Long Single: Both are 203 cm long, but King Single is 107 cm wide (wider) and Long Single is 92 cm wide (same as standard single, just longer). Two Long Singles = one King. Two King Singles ≈ one Super King.

Double Bed Size
138 × 188 cm · 54″ × 74″ · $700–$1,500
The double bed size (also called a full bed) measures 138 × 188 cm. About 10% of Australians sleep on a double. While technically able to fit two adults, each person only gets 69 cm of sleeping width — less than a single bed. Double beds in Australia are predominantly used by single adults or as a budget-friendly guest room option.
- Minimum room size: 3.2 m × 3.4 m
- Ideal room size: 3.5 m × 3.8 m
- Same length as a single (188 cm) — not suitable for people over 180 cm tall
- 46 cm wider than a standard single — significant extra space for solo sleepers
- For couples who can stretch to a Queen, the extra 15 cm width is almost always worth it

Queen Size Bed Dimensions Australia
153 × 203 cm · 60″ × 80″ · $800–$3,000+
The queen bed is Australia's most popular choice — 61% of Australians sleep on one. At 153 × 203 cm, it gives each person in a couple 76.5 cm of sleeping width and fits comfortably in most standard Australian master bedrooms. If you're unsure which size to choose, queen is almost always the right answer.
- Minimum room size: 3.0 m × 4.0 m
- Ideal room size: 3.5 m × 4.5 m
- 61% of Australians sleep on a queen — most widely available size in stores
- Australian Queen (153 × 203 cm) ≈ US Queen (152 × 203 cm) — nearly identical, 1 cm difference
- Widest range of bedding available at all Australian linen retailers
61% of Australians sleep on a queen mattress. It's the most-stocked size in stores, has the widest bedding range, and fits almost every standard master bedroom. For couples, this is the minimum recommended size.

King Size Bed Dimensions Australia
183 × 203 cm · 72″ × 80″ · $1,000–$5,000+
An Australian king size bed measures 183 × 203 cm. That's 30 cm wider than a queen — giving each person in a couple around 91.5 cm of space, roughly equivalent to sleeping on a king single each. Around 21% of Australians sleep on a king, and the number is growing.
When checking king size bed measurements AU, one critical fact: the Australian King is 10 cm narrower than the US King (183 cm vs 193 cm). US-sourced king bedding will usually be too wide for an Australian king mattress.
- Minimum room size: 3.2 m × 4.2 m
- Ideal room size: 4.0 m × 4.5 m
- 21% of Australians sleep on a king — popularity rising
- Bed frame: typically 188–193 cm wide × 207–212 cm long
- Available as split king (two long singles) for adjustable base setups
- US King = 193 × 203 cm — 10 cm wider than Australian King
- UK King = 150 × 200 cm — closer to Australian Queen in size
Australian King = 183 × 203 cm. US King = 193 × 203 cm. That 10 cm difference matters — US sheets purchased online will likely be too wide. Always buy Australian-standard bedding for your king bed.

Super King Bed Size
203 × 203 cm · 80″ × 80″ · $1,500–$6,000+
The super king is Australia's largest standard bed size at a perfectly square 203 × 203 cm. It's 20 cm wider than a standard King and provides unmatched sleeping space — ideal for large master suites, luxury bedroom setups, or families who regularly co-sleep.
- Minimum room size: 4.0 m × 4.5 m
- Ideal room size: 4.5 m × 5.0 m
- 20 cm wider than standard King — a significant increase
- Super king bedding is specialty — less available than queen/king
- Note: a super king is NOT two king singles side by side (that would be 214 cm wide)
Super King bed frames are large and heavy. Before purchasing, measure your doorways (standard AU door = 82 cm wide), hallways and stairwells. A2Z Furniture can advise on delivery and assembly requirements.
Mattress vs Bed Frame: What Size Frame Do You Need?
Frames are always slightly larger than the mattress
A bed frame is always slightly larger than the mattress it holds. The mattress sits inside or on top of the frame, adding 4–10 cm to each dimension. Here are typical Australian bed frame dimensions for each standard mattress size:
| Bed Size | Mattress Dimensions | Typical Frame / Base Dimensions |
|---|---|---|
| Single | 92 × 188 cm | 96–100 × 192–196 cm |
| Long Single | 92 × 203 cm | 96–100 × 207–210 cm |
| King Single | 107 × 203 cm | 112–116 × 207–210 cm |
| Double | 138 × 188 cm | 142–146 × 192–196 cm |
| Queen | 153 × 203 cm | 158–163 × 207–212 cm |
| King | 183 × 203 cm | 188–193 × 207–212 cm |
| Super King | 203 × 203 cm | 208–213 × 207–212 cm |
Table 2: Australian mattress dimensions vs typical bed frame / base dimensions. Frame dimensions vary by brand.
- Always check the product listing's 'mattress size compatibility' and 'overall dimensions'
- Gas-lift storage beds add 4–8 cm to height profile
- Slat spacing: for mattress warranty validity, slats should be no more than 6 cm apart
- Mattress height: 25–36 cm is standard in Australia, average ~30 cm
- Fitted sheets need to match mattress depth — look for 'deep wall' sheets for mattresses 35 cm+

Room Size Requirements per Bed Size
Allow 60–90 cm clearance on each walkable side
The bed's footprint is only part of the equation. You need enough clearance around the bed for daily use. Allow at least 60–90 cm on each side and 60 cm at the foot of the bed as a minimum.
| Bed Size | Minimum Room Size | Ideal Room Size |
|---|---|---|
| Single | 2.5 m × 3.0 m | 3.0 m × 3.5 m |
| Long Single / King Single | 2.6 m × 3.2 m | 3.0 m × 3.5 m |
| Double | 3.2 m × 3.4 m | 3.5 m × 3.8 m |
| Queen | 3.0 m × 4.0 m | 3.5 m × 4.5 m |
| King | 3.2 m × 4.2 m | 4.0 m × 4.5 m |
| Super King | 4.0 m × 4.5 m | 4.5 m × 5.0 m |
Table 3: Minimum and ideal room sizes for each Australian bed size.
- Comfortable clearance each side: 90 cm
- Minimum clearance each side: 60 cm
- Clearance at foot: 60 cm min; 90 cm if you have a blanket box
- Wardrobe doors need 60–80 cm swing clearance in front
- Ensuite bathroom doors typically need 90 cm swing clearance
Before buying, mark out the exact bed dimensions on your floor using masking tape. Then add the clearance zones. Stand in the space and open imaginary drawers and wardrobe doors. This 5-minute exercise prevents expensive mistakes.
Australian vs US vs UK Bed Sizes
Same names, very different dimensions
Australian bed sizes are unique internationally. The same size name (e.g. 'King') describes very different dimensions in Australia, the US and the UK. Here is a full comparison:
| AU Size | AU (cm) | US (cm) | UK (cm) | Key Difference |
|---|---|---|---|---|
| Single | 92 × 188 | 97 × 191 (Twin) | 90 × 190 | Very similar |
| Long Single | 92 × 203 | 97 × 203 (Twin XL) | — | AU 5 cm narrower than US |
| King Single | 107 × 203 | — | — | Uniquely Australian |
| Double | 138 × 188 | 135 × 190 (Full) | 135 × 190 | Very similar |
| Queen | 153 × 203 | 152 × 203 | 150 × 200 | Nearly identical to US ✓ |
| King | 183 × 203 | 193 × 203 | 150 × 200 | AU King 10 cm narrower than US |
| Super King | 203 × 203 | — | 183 × 200 | Different dimensions |
Table 4: Australian bed sizes compared to US and UK equivalents. Highlighted rows = most commonly confused.
- The only size that transfers internationally is Queen — AU and US Queen are nearly identical (1 cm difference in width)
- Australian King is 10 cm narrower than US King — US king bedding will NOT fit properly
- UK King (150 × 200 cm) ≈ Australian Queen — if buying from UK, use AU Queen sheets
- King Single has no equivalent in the US or UK — it's a uniquely Australian size
- IKEA Australia uses non-standard dimensions — always check the cm measurements, not the size name
IKEA Australia uses non-standard dimensions for several bed sizes. Their 'Single' can be 80 cm wide (not 92 cm). Always check the IKEA product's specific centimetre measurements before buying matching bedding or accessories from other retailers.
How to Choose the Right Bed Size for You
A practical decision framework
- Small room / tight budget → Single
- Normal room, under 185 cm → King Single
- Over 185 cm → Long Single or King Single
- Want space, generous room → Queen
- Small room → Double (69 cm each — tight)
- Standard master bedroom → Queen (best value)
- Large master bedroom → King (~91.5 cm each)
- Luxury suite → Super King
- Occasional visitors → Queen
- Kids regularly co-sleep → King
- Large family / frequent co-sleeping → Super King
- Under 185 cm → any size works
- 185–190 cm → King Single, Queen, King (203 cm long)
- Over 190 cm → seek 'extra long' options
- Avoid: Single + Double (only 188 cm long)
Split King and Adjustable Beds Explained
Two long singles = one king
The split king is not a separate bed size — it's a configuration. Two long single mattresses (92 × 203 cm each) placed side by side create the exact same dimensions as a standard King (183 × 203 cm). This setup is used for:
- Adjustable bed bases where each partner wants independent head/foot control
- Couples with different firmness preferences
- Reducing partner disturbance from movement
- Hotels and FIFO accommodation where beds need to be easily separated
- Split King bedding: 1 King flat sheet + 2 Long Single fitted sheets + 2 pillowcases
- Do NOT confuse King Single (107 × 203 cm) with Long Single (92 × 203 cm) for split setups
- Two king singles ≈ Super King (214 cm wide — slightly larger than 203 cm)
King Single ≠ Long Single. King Single is 107 cm wide (wider). Long Single is 92 cm wide (same width as standard single, just longer). Two Long Singles = one King. Two King Singles ≈ one Super King.
Frequently Asked Questions
The most-searched questions about Australian bed sizes
The Queen bed (153 × 203 cm) is the most popular bed size in Australia, used by 61% of Australians. It balances sleeping comfort with room footprint and fits most standard master bedrooms. The Queen is closely followed by the King at 21%.
Standard Australian bed sizes in cm are: Single (92 × 188), Long Single (92 × 203), King Single (107 × 203), Double (138 × 188), Queen (153 × 203), King (183 × 203), and Super King (203 × 203).
King size bed dimensions in Australia are 183 cm wide by 203 cm long (1,830 mm × 2,030 mm / 72″ × 80″). The bed frame is typically slightly larger — approximately 188–193 cm wide by 207–212 cm long.
No. An Australian King is 183 × 203 cm. A US King (Eastern King) is 193 × 203 cm — 10 cm wider. US king bedding will generally be too wide for an Australian king mattress. Always purchase Australian-labelled sheets for your Australian king bed.
An Australian queen size bed (mattress) measures 153 cm wide by 203 cm long. The recommended queen bed frame dimensions are approximately 158–163 cm wide by 207–212 cm long, as frames are always slightly larger than the mattress.
An Australian King Single bed measures 107 cm wide by 203 cm long. It is 15 cm wider and 15 cm longer than a standard single, and is a uniquely Australian size — it has no direct equivalent in the US or UK.
For a king size bed (183 × 203 cm), you need a minimum room size of 3.2 m × 4.2 m. For a comfortable layout with proper clearance and room for bedside tables, a room of 4.0 m × 4.5 m or larger is ideal.
An Australian King measures 183 × 203 cm. A Super King measures 203 × 203 cm — 20 cm wider and a perfect square. The Super King requires a larger room (minimum 4 m × 4.5 m) and super king bedding can be harder to find than king bedding.
A long single measures 92 × 203 cm — same width as a standard single but 15 cm longer. It's primarily used in split king / adjustable bed setups (two long singles side by side form a standard King), and also suits taller adults with limited bedroom width.
