Single vs King Single Bed & Mattress Package: Which Is Better?
A Single bed and mattress package is the most compact option, while a King Single gives the sleeper extra width and length. In Australia, a standard Single mattress is approximately 92 × 188 cm and a King Single is approximately 107 × 203 cm. The King Single is therefore about 15 cm wider and 15 cm longer at mattress level.
For a child's room, teenager's room, guest room or compact apartment, the decision usually comes down to available floor space, the sleeper's height and how long you want the bed to remain suitable.

Mattress dimensions are standard approximations; the complete bed-frame dimensions vary. Always check the individual product measurements. You can compare all common sizes in the Australian bed sizes guide.
When a Single package makes more sense
A Single package works well when every centimetre matters. It can leave extra room for a desk, drawers, toy storage or a wider walkway, making it a practical option for narrow bedrooms and multipurpose spaces.
It is also useful for an occasional guest room where the bed needs to coexist with home-office furniture. If the intended sleeper is taller or the bed will be used for many years by a growing child, compare the longer King Single before deciding.
When a King Single package is worth the extra space
A King Single may be a better long-term choice for a growing child or teenager because it provides approximately 15 cm more width and length at mattress level. It can also suit taller adults who sleep alone but do not have room for a Double.
The extra space is useful only if the room remains functional. Check whether a bedside table, wardrobe doors, study desk and walkway still fit after allowing for the complete outer dimensions of the frame.
Measure the actual room layout
Do not decide from the mattress size alone. The headboard and side rails add to the final footprint, and the surrounding furniture determines whether the room feels easy to use.
- Measure the complete product width and length shown on the product page.
- Mark the outline on the floor with painter's tape.
- Check the path from the doorway to the bed.
- Open wardrobe doors, drawers and windows within the taped layout.
- Place a box where the bedside table or desk will sit.
- Confirm the packaged components can pass through doors, hallways, stairs or lifts.
Think about the next few years
For a child's room, consider both today's fit and likely future use. A compact Single may be ideal now and keep the room open for play or study. A King Single may reduce the need to change sizes as the child grows, provided the room can accommodate it comfortably.
There is no universal winner. The better value is the size that fits the room, the sleeper and the expected length of use without creating access problems.
Check the mattress and frame as a complete package
A package simplifies matching the bed and mattress, but the details still matter:
- Mattress feel: use the product description to compare comfort and firmness.
- Mattress height: check how the mattress thickness works with the headboard and preferred getting-in height.
- Frame material: consider cleaning, style and the intended room.
- Included parts: review what arrives with the bed and what requires assembly.
- Availability by size: not every design is offered in both Single and King Single.
Browse the current bed and mattress package collection. If mattress thickness is part of your decision, read the 20cm vs 30cm mattress guide.
