A double bed is 138cm wide by 188cm long — narrower and shorter than a queen, and the only Aussie standard bed under 190cm long. That length matters if you or your partner is over 180cm tall: your feet hang off the end. We hold over 175 double bed frames in stock across our Sydney, Melbourne and Brisbane warehouses, from $80 metal frames to $700 storage beds.
What size is a double bed in Australia?
A double bed measures 138cm wide by 188cm long. That's 15cm narrower than a queen and 15cm shorter. The shorter length is the key fact most buyers miss — Australian doubles are not the same size as queens with less width. If anyone in the bed is over 180cm tall, you'll outgrow a double.
Double beds suit single sleepers wanting more room, couples in small apartments under 30, kids' rooms before a queen upgrade, and guest rooms. Most adult couples find a double too narrow within 12 months of moving in together.
Should you buy a double or jump to a queen?
Buy a double if the room is under 3.2m wide, the sleeper is under 180cm tall, or you'll only use it for one to three years before upgrading. Buy a queen if you're a couple planning to stay in the bed long-term, anyone is over 180cm, or you sleep with a pet on the bed.
The cost difference between a quality double frame ($150-$300) and queen frame ($180-$400) is $30-$100. The cost difference between a double mattress and queen mattress is roughly the same. Most regret stories come from couples who bought a double to save $80 and replaced it within two years.

What's the double bed size in cm vs queen?
Double is 138cm x 188cm. Queen is 153cm x 203cm. Queen is 15cm wider and 15cm longer. The length difference matters more than the width for tall sleepers.
What size mattress fits a double bed frame?
A standard double mattress: 138cm x 188cm. Australian double mattress sizes are fixed nationwide — no king double, no super double, no full size (that's a US term equivalent to our double).

A double bed frame works hardest with the right supporting pieces. Add a double mattress sized 138 x 188cm, a headboard that matches the frame's bolt hole spacing, and bedside tables roughly 5cm shorter than the finished mattress top.
