Standard Australian bed sizes range from the compact single to the massive super king, each designed to meet specific lifestyle needs.

The Australian bed size guide below shows metric measurements to ensure a perfect fit for modern bedrooms. While lengths are usually consistent, widths vary significantly.

Choosing the right mattress size is crucial for getting a good night's rest while keeping your bedroom functional and spacious. Here’s a breakdown of standard Australian bed sizes, along with their key benefits and ideal use cases.

Single Beds

As the most space-efficient option available, the size of a single bed is designed to maximise your available floor area.

Best for: Children’s bedrooms, smaller guest rooms or tight studio apartments.

Benefits: Leaves plenty of room for bedroom furniture, play areas or study desks while still providing a comfortable sleep space for a child or smaller adult.

Providing a comfortable 137cm of width, the double bed is a highly versatile middle-ground option.

Best for: Solo sleepers who love extra room or older teenagers.

Benefits: Fits perfectly into smaller secondary bedrooms or guest rooms. While it certainly can fit two adults, some couples find the size of a double bed a bit cramped and prefer to use it as a luxurious solo sleeper.

With dimensions of 153cm x 203cm, it’s no surprise that the queen bed is the absolute favourite of most Australians. The dimensions of a queen-sized bed strike the perfect balance between everyday comfort and room practicality.

Best for: Most master suites, couples and premium guest rooms.

Benefits: Delivers ample sleeping room for two adults to sleep comfortably while still leaving enough space for bedside tables, tallboys and easy movement around the room.

If you have the floor space and want more room to stretch out, a king-sized bed offers a luxurious sleeping experience. A standard king bed provides the same width as two single beds placed side by side.

Best for: Large master bedrooms, couples and restless sleepers.

Benefits: Offers generous personal space, helping reduce partner disturbance and creating a more comfortable sleep experience.

For those seeking the ultimate in luxury and space, the super king bed provides an even larger sleeping area designed for maximum comfort.

Best for: Spacious master bedrooms, families with children or pet owners.

Benefits: The super king bed offers exceptional room to spread out, ensuring minimal partner disturbance and plenty of extra space for relaxed weekend mornings.
