What’s the Difference Between Bed Sizes in Australia? (Full Mattress Size Guide)

When buying a new bed or mattress, one of the most common questions we hear is:

“What size bed should I get?”

Australian bed sizes are different from US and UK sizing, and choosing the wrong size can mean comfort issues, cramped spaces, or a bed that simply doesn’t fit your room.

This guide breaks down the standard Australian bed sizes, who they’re best for, and how to choose the right one for your space.
