The standard measurements for a double size bed in Australia are 138 cm wide x 188 cm long. In simple terms, a double bed is designed to comfortably sleep one adult or two people who don’t mind sleeping close together. It offers more width than a single bed but is more compact than a queen, making it a popular choice for guest rooms, teenagers, apartments, and smaller master bedrooms.
The main reason Australians choose a double size bed is balance — it provides extra sleeping space without taking up too much room, making it ideal for modern homes where space efficiency matters.
