Single bed matrix is commonly used as a search phrase when looking for information about single bed and mattress measurements, sizes, specifications or comparison tables. In Australia, a standard single mattress is generally 92 cm wide × 188 cm long, providing a compact sleeping surface designed for one person.
A single bed is one of the most space-efficient Australian bed sizes, making it particularly suitable for children's bedrooms, teenagers, guest rooms, bunk beds, compact bedrooms and rooms where floor space is limited. While the mattress size is relatively compact, the overall dimensions of the bed frame can be slightly larger depending on the design, headboard and construction.
Understanding the single bed matrix is useful when comparing mattress sizes, choosing bedding, planning a bedroom layout or selecting a compatible bed frame.
| Bed Size | Width | Length | Typical Use |
|---|---|---|---|
| Single | 92 cm | 188 cm | Children, teens, guests and compact rooms |
| Single Long | 92 cm | 203 cm | Taller single sleepers |
| King Single | 107 cm | 203 cm | Teens and adults wanting more space |
| Double | 138 cm | 188 cm | Larger sleeping surface |
| Queen | 153 cm | 203 cm | Couples and spacious bedrooms |
| King | 183 cm | 203 cm | Couples wanting maximum width |
Australian mattress dimensions can vary slightly between manufacturers, so checking the specific manufacturer's measurements is recommended before purchasing a frame or bedding.
The standard Australian single mattress measures 92 cm × 188 cm.
In millimetres, this is:
In imperial measurements, it is approximately 3 ft × 6 ft 2 in.
The compact dimensions make a single bed particularly useful when you need comfortable sleeping space without dedicating a large proportion of the bedroom to the bed.
A single long mattress keeps approximately the same width as a standard single but adds 15 cm of length.
| Feature | Single | Single Long |
|---|---|---|
| Width | 92 cm | 92 cm |
| Length | 188 cm | 203 cm |
| Best for | Children and compact rooms | Taller sleepers |
| Extra length | — | 15 cm |
A single long can be a useful choice for teenagers or adults who want the compact width of a single but need additional legroom.
A king single provides both additional width and length.
A standard king single is approximately 107 × 203 cm, compared with 92 × 188 cm for a standard single.
That means a king single gives the sleeper an additional:
For a growing child or teenager, a king single can provide more room to move and may remain suitable for longer as they grow.
Measure the available floor area before purchasing the bed.
Remember to leave enough room around the bed for walking, opening drawers and placing bedside furniture.
For children, the standard single is often perfectly practical.
For taller teenagers or adults, a single long or king single can provide considerably more legroom.
The mattress dimensions and external bed-frame dimensions are not necessarily identical.
A substantial headboard, footboard or side frame can increase the overall footprint, so always check the assembled dimensions of the complete bed.
If buying for a growing child, consider how long you want the bed to remain suitable.
A king single costs more space but provides additional width and length that can accommodate a growing teenager or adult.
Pocket springs provide individually responsive support and can be found in a variety of firmness levels.
Memory foam conforms to the body and can provide a cushioning feel.
Hybrid mattresses combine spring support with foam or other comfort materials.
Latex mattresses can provide responsive support with a distinctive buoyant feel.
Some single mattresses are compressed and rolled for convenient delivery and setup.
The best mattress type depends on firmness preference, sleeping position, support requirements and personal comfort.
The mattress itself occupies approximately 92 × 188 cm, but the bedroom needs additional space for movement.
As a practical guideline, allow generous clearance around the sides and foot of the bed wherever possible. One Australian mattress guide recommends approximately 1 metre of space around the sides and end for comfortable movement.
For particularly compact rooms, measure the bed and surrounding furniture together before deciding on the layout.
A standard single is a practical first full-size bed for many children.
It leaves more floor area available for toys, storage, desks and play.
A single can work well for teenagers, although a king single may offer greater long-term comfort.
A single bed is ideal when a guest room also needs to function as an office, study or multipurpose room.
Single mattresses are commonly used in bunk beds and provide an efficient way to accommodate multiple sleepers.
A single bed can maximise available floor space in studios and compact bedrooms.
A single bed does not need to feel small or temporary.
Create a polished bedroom by pairing it with:
In smaller bedrooms, using vertical storage can help preserve valuable floor space while keeping the room organised.
Always select bedding specifically designed for the mattress size.
A standard single mattress measures approximately 92 × 188 cm, while a single long mattress is approximately 92 × 203 cm. Standard single bedding may therefore not fit a single-long mattress correctly.
Check the product measurements rather than relying solely on the word "single", particularly when purchasing fitted sheets and mattress protectors.
