mattress Size guide
Australian mattress sizes
Six standard sizes, what each one measures, and how much room it needs. Measure the room before you choose the bed.

2 · Compare with (optional)
3 · Your bedroom, in metres
Before you measure
Measure the room, not the bed
Allow at least 600 mm to walk past the bed on any side you need to use, and check the swing of the door and the wardrobe.
Measure the way in
Doorways, stair turns, lift depth and any tight corner. A Super King mattress does not bend.
Add the base
An ensemble or adjustable base adds height. Sitting on the edge should leave your feet flat on the floor.
Check the bed frame
Frames are made to the mattress size, but internal dimensions vary. Take the mattress measurements to the frame, not the other way around.
Frequently asked questions
Is a Queen big enough for two people?
A Queen gives each sleeper 765 mm. That is the most common choice in Australia. A King gives each sleeper 915 mm, which is close to the width of a King Single each.
What is the difference between a Double and a King Single?
A Double is 300 mm wider but 150 mm shorter. A King Single is the longer of the two, at 2030 mm.
What is a Split Queen?
Two 770 mm wide mattresses that together make up a Queen, so each side of an adjustable base moves on its own. It is listed as a size on the adjustable bed pages.
Do Australian sizes match US or European sizes?
No. A US Queen and an Australian Queen are different, and European sizes are different again. Buy the mattress, base and bedding to the same standard.
