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.
Here’s a clear breakdown of double bed dimensions in Australia:
Width: 138 cm
Length: 188 cm
Also known as: Full bed (internationally)
These measurements apply to the mattress size only. Bed frames can vary slightly depending on design, headboards, footboards, and frame thickness.
When researching what are the measurements for a double size bed, it’s important to note that sizes vary internationally.
138 cm x 188 cm
135 cm x 190 cm
137 cm x 191 cm (called a “Full”)
Varies by country, commonly 140 cm x 200 cm
This is why Australians should always shop by local measurements, especially when buying bed frames, mattresses, or linen from Australian retailers like House of Isabella Australia.
Understanding how a double bed compares helps you choose the right size.

In simple terms, a double bed offers more width than a king single but less length and space than a queen.
While the mattress measures 138 cm x 188 cm, you’ll need additional room for comfort and movement.
Minimum room size: 3 m x 3 m
Ideal room size: 3.2 m x 3.2 m or larger
This allows space for:
Bedside tables
Walking clearance
Wardrobes or drawers
House of Isabella Australia recommends leaving at least 75 cm of walking space on accessible sides of the bed for a well-balanced bedroom layout.
Double beds come in a wide range of styles to suit different interiors and lifestyles.

It’s important to remember that bed frame dimensions are larger than mattress dimensions.

Slim-profile bed frames for small spaces
Upholstered textures in neutral tones
Storage-integrated double beds
Minimalist timber designs
