Australian mattress sizes

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

Australia has six standard mattress sizes: Single (920 × 1880 mm), King Single (1070 × 2030 mm), Double (1370 × 1880 mm), Queen (1530 × 2030 mm), King (1830 × 2030 mm) and Super King (2030 × 2030 mm). The Queen is the most common choice for two people.

How do I measure for a new bed?

1. 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.

2. Measure the way in

Doorways, stair turns, lift depth and any tight corner. A Super King mattress does not bend.

3. Add the base

An ensemble or adjustable base adds height. Sitting on the edge should leave your feet flat on the floor.

4. 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

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.
 
A Double is 300 mm wider but 150 mm shorter. A King Single is the longer of the two, at 2030 mm.
 
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.
 
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.
 

Allow at least 600 mm on any side you need to walk past. For a Queen, that means a room of about 3.0 × 3.2 m or larger.

Measure first. A Super King is 2030 mm wide and doesn’t bend, so check doorways, stair turns and lift depth before you order.
