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.

Single92cm x 187cm
Single extra long92cm x 203cm
King single106cm x 203cm
Double137cm x 187cm
Queen153cm x 203cm
King183cm x 203cm
Super king203cm 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.

Double – 137cm x 187cm

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.

King – 183cm x 203cm

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

Picture not described

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.
