Mattress sizes Australia: A complete guide
If you're looking to purchase a mattress in the near future, it's important to get your head around the various mattress sizes in Australia.
In the market for a new mattress? There are loads of questions you need to keep in mind, but one of the simpler items you can tick off your list is gaining an understanding of mattress sizes.
We're all familiar with terms like single, queen and king, but it's good to get a clear idea of exact mattress dimensions. Otherwise, you may find yourself struggling to fit an oversized mattress onto a misfitting bed frame, or one that takes up far too much space in your room.
For more general information on purchasing your perfect mattress, head over to our complete guide here. Once you've done your homework, you're all set to check out our rundown of the 18 best mattresses in Australia.
Mattress sizes Australia
Here are the dimensions of the most common mattress types in Australia. As a general rule, your mattress should be 10cm longer than you and your sleeping partner.
The major variables within mattress size categories are height and weight. You'll need to get this information from the mattress manufacturer or retailer.
|Mattress size||Typical dimensions (width x length)|
|Single||92cm x 187cm|
|Single extra long||92cm x 203cm|
|King single||106cm x 203cm|
|Double||137cm x 187cm|
|Queen||153cm x 203cm|
|King||183cm x 203cm|
|Super king||203cm x 203cm|
Most mattresses are available in single, king single, double, queen and king size. Extra long single and super king mattresses aren't terribly difficult to get, but this size may not be available for your ideal mattress.
Which mattress is right for me?
Single – 92cm x 187cm
These beds are perfect for individual sleeping and are well-suited for kids' bedrooms and apartment living.
Single extra long – 92cm x 203cm
Do your legs constantly dangle off the end of beds? Then this extra-lengthy mattress is for you.
King single – 106cm x 203cm
A king single can be a great investment for growing kids and teens who are likely to outgrow a single mattress.

A very common style of mattress, the double size can accomodate solo sleepers and couples of all ages.
Queen – 153cm x 203cm
If you're an individual or a couple craving a bit more sleeping space, the queen is a great option.

If you're willing to splash out for more luxurious nights of sleep, you can't go wrong with a king.
Super king – 203cm x 203cm
These decadent square-shaped mattresses are perfect for couples looking for the roomiest possible nights of sleep. It also doubles as a great venue for family activities like movie night.
Mattress buying tips
Getting your perfectly-sized mattress is only half the battle. Beds, in their various forms, must also be carefully considered when allocating space in your bedroom. Traditional wisdom in the world of interior design is to leave 60cm of clearance around the sides of your bed.
Bed bases generally conform to the same dimensions as the mattresses they are designed to support, but in some cases may be wider and larger. Full-blown bed frames obviously add much more bulk to your mattress, so be sure to carefully check the dimensions of any bed frame you purchase.
Naturally, larger mattresses are more expensive, so be sure to keep that in mind when shopping around. For information around foam versus spring mattresses, cost, firmness and more, check out our complete mattress buying guide.
