Quick answer: In Australia a Single mattress is 92 cm × 188 cm, King Single is 107 cm × 203 cm, Double is 138 cm × 188 cm, Queen is 153 cm × 203 cm, King is 183 cm × 203 cm, and Super King is 203 cm × 203 cm.
TL;DR: Australia uses its own mattress sizing, and it does not match the United States or the United Kingdom. The two sizes people get wrong most often are King and Double. An Australian King is 183 cm wide, which is narrower than a US King at 193 cm but wider than a UK King at 150 cm. An Australian Double is 138 cm × 188 cm, which is shorter than a Queen by 15 cm — the length changes, not just the width. Queen is the most common size in Australian homes. When buying sheets, match the fitted sheet to your mattress size and check the pocket depth against how thick your mattress actually is, because a 40 cm mattress will not stay in a sheet cut for 30 cm.
Key facts
- A Queen bed in Australia measures 153 cm × 203 cm.
- An Australian King mattress is 183 cm × 203 cm, which is 10 cm narrower than a US King.
- Australian Single and Double mattresses are both 188 cm long; every larger size is 203 cm long.
- A King Single is 107 cm × 203 cm — the same length as a Queen but far narrower.
- Two Australian King Singles pushed together measure 214 cm wide, which is wider than a Super King.
- Mattress dimensions vary by roughly ±2 cm between manufacturers, so measure your own before buying fitted sheets.
The Full Australian Bed Size Chart
These are the standard Australian mattress dimensions. Width is always given first.
| Size | Width | Length | Dimensions (cm) | Typically suits |
|---|---|---|---|---|
| Single | 92 cm | 188 cm | 92 × 188 | Children, single sleepers, bunks |
| King Single | 107 cm | 203 cm | 107 × 203 | Taller teens, guest rooms |
| Double | 138 cm | 188 cm | 138 × 188 | One adult with room, two at a squeeze |
| Queen | 153 cm | 203 cm | 153 × 203 | Two adults — the most common AU size |
| King | 183 cm | 203 cm | 183 × 203 | Two adults with space, co-sleeping |
| Super King | 203 cm | 203 cm | 203 × 203 | Large main bedrooms, a perfect square |
The length jump matters more than people expect. Single and Double are both 188 cm long. Every size from King Single upward is 203 cm. If you are over about 183 cm tall, a Double is not simply "narrower than a Queen" — it is also 15 cm shorter, and that is what you will notice at your feet.
Super King is square. At 203 cm × 203 cm it is exactly as wide as it is long, which is worth knowing because bedding is not always cut symmetrically and a fitted sheet can go on the wrong way round.
How Australian Sizes Compare to the US and UK
This is where imported bedding causes problems. The names are shared; the dimensions are not.
| Size name | Australia | United States | United Kingdom |
|---|---|---|---|
| Single | 92 × 188 | 97 × 191 (Twin) | 90 × 190 |
| Double | 138 × 188 | 137 × 191 (Full) | 135 × 190 |
| Queen | 153 × 203 | 152 × 203 | 150 × 200 |
| King | 183 × 203 | 193 × 203 | 150 × 200 |
| Super King | 203 × 203 | 183 × 213 (Cal King) | 180 × 200 |
The King is the trap. A US King is 193 cm wide against Australia's 183 cm — a 10 cm difference that means US King fitted sheets are loose on an Australian King. A UK King is 150 cm wide, which is closer to an Australian Queen than an Australian King. If you order King bedding from an overseas site, you are very likely ordering the wrong thing.
Australian and US Queens are nearly identical, differing by about 1 cm in width, so Queen is the one size where imported bedding usually works.
Double and Full are close but not equal. A US Full is 3 cm longer than an Australian Double.
Choosing Sheets: The Three Numbers That Matter
Sheet sizing fails for three reasons, and only one of them is the bed size.
1. The fitted sheet's pocket depth
This is the most common sizing mistake. A fitted sheet is cut for a maximum mattress thickness, called the pocket depth. Modern Australian mattresses are frequently 30 cm to 40 cm thick once you add a pillow top, and older sheets were often cut for 25 cm to 30 cm. A sheet that is too shallow will pop off the corners every night no matter how correct the width and length are.
Measure your mattress from the seam at the bottom to the top surface, then buy a sheet rated at or above that figure. As a reference point, a bamboo sheet set with a 40 cm deep pocket states its component sizes explicitly: a 270 × 265 cm flat sheet, a 182 × 203 cm fitted sheet, and 48 × 74 cm pillowcases, with elastic running 360 degrees around the fitted sheet. Those published numbers are what you want to see before buying — a set that only says "King" tells you less than a set that gives you centimetres.
2. The flat sheet's overhang
A flat sheet needs to be substantially wider than the mattress so it can tuck. On a King at 183 cm wide, a flat sheet around 270 cm gives roughly 43 cm of overhang each side, which is enough to tuck properly.
3. Manufacturer variance
Australian mattress dimensions vary by around ±2 cm between brands. This is normal and it is why the numbers on a product page can differ slightly from the standard chart. One bamboo terry mattress protector lists its range as Single 91 × 190, King Single 106 × 203, Double 137 × 190, Queen 152 × 203, King 180 × 203 and Super King 204 × 204 — all within a couple of centimetres of the standard chart above. Elastic absorbs that difference; the number you cannot fudge is depth.
Pillowcase and Quilt Sizes
Bed size is only half of what goes on the bed.
Standard Australian pillowcases are about 48 cm × 74 cm. King pillowcases run roughly 48 cm × 90 cm. A King bed does not require King pillows — many people use two standard pillows side by side, which spans 96 cm on a 183 cm bed.
Quilt covers are sized to the bed, not the mattress, and are cut with drop on each side. A Queen quilt cover is typically around 210 cm × 210 cm, and a King around 245 cm × 210 cm. If your bed sits high off the floor, size up rather than matching exactly.
Fitting the Bed to the Room
Choosing a size is as much about the room as the sleeper.
Leave 60 cm to 75 cm of walking space on any side of the bed you need to walk down. Below about 60 cm a gap stops feeling like a walkway.
Work from the room's short wall. A Queen at 153 cm wide plus two bedside tables at roughly 45 cm each needs about 243 cm of wall before you have allowed any clearance. In a 3 m wide room that fits comfortably; in a 2.7 m room it is tight.
Check the doorway and the turn, not just the room. A Super King mattress is 203 cm square and will not bend. Standard internal doorways in Australian homes are around 82 cm wide, which is fine for a mattress on its side, but a tight hallway corner is where large mattresses actually get stuck.
Our guide on how to choose a bedside table covers matching table height to mattress height, which is the other measurement people skip.
Which Size Should You Buy?
- Two adults, standard room: Queen. It is the default in Australia for good reason and bedding is easiest to find.
- Two adults, and one of you moves a lot: King. The extra 30 cm of width over a Queen is the single biggest improvement to shared sleep.
- One adult who wants space: Double gives width, but check your height against the 188 cm length. If you are tall, a King Single is longer at 203 cm despite being narrower.
- Guest room: King Single. Full adult length, far less floor space than a Double.
- Child moving out of a cot: Single. King Single if you would rather buy once.
Making the Bed Work Once It's the Right Size
Once the size is right, comfort comes down to layers. Our guide on cushion size and layering covers proportions for each bed size, how to choose a doona warmth rating covers seasonal weight, and how to make your bedroom cosy in winter covers the rest of the room.
For hot sleepers, breathable fibres matter more than thread count. A cooling bamboo sheet set is designed around airflow and moisture handling rather than density alone, and includes a fitted sheet, flat sheet and two pillowcases.
Ready to Measure Up?
Measure your mattress width, length and depth before you buy anything — three numbers, two minutes, and it removes almost every sizing problem. Then match the fitted sheet to the depth, not just the size name. Browse the full Pattan Australia range once you have your measurements.
Frequently asked questions
What size is a queen bed in Australia?
An Australian Queen mattress measures 153 cm × 203 cm. It is the most common bed size in Australian homes. It is about 1 cm narrower than a US Queen and 3 cm wider than a UK Queen, so imported Queen bedding usually fits acceptably.
How wide is a king bed in Australia?
An Australian King mattress is 183 cm wide and 203 cm long. This is 10 cm narrower than a US King, which is 193 cm wide, and 33 cm wider than a UK King at 150 cm. King bedding bought overseas frequently does not fit Australian King beds.
What is the difference between a double and a queen in Australia?
A Double is 138 cm × 188 cm and a Queen is 153 cm × 203 cm. The Queen is 15 cm wider and also 15 cm longer. The length difference matters for anyone over roughly 183 cm tall, since a Double is one of only two Australian sizes still cut to 188 cm.
Is a king single longer than a double?
Yes. A King Single is 203 cm long against a Double's 188 cm, so a King Single is 15 cm longer despite being 31 cm narrower. For a tall single sleeper a King Single is usually the better choice.
What depth fitted sheet do I need?
Measure your mattress from the bottom seam to the top surface, including any pillow top, and buy a fitted sheet rated at or above that number. Many current Australian mattresses are 30 cm to 40 cm thick, while older sheets were cut for 25 cm to 30 cm, which is why sheets slip off the corners.
Are Australian and US bed sizes the same?
No. Queen is nearly identical at about 1 cm difference, but King differs by 10 cm in width, and the US uses Twin and Full where Australia uses Single and Double, each with slightly different dimensions. Check centimetres rather than trusting the size name.
