The right choice depends on who will use the bed, how much room you have, whether the bedroom also needs a desk or storage, and how long you want the bed to last. This guide compares king single and single beds for real NZ homes, including kids’ rooms, teen bedrooms, guest rooms, rentals, apartments and townhouses.
TL;DR: King Single vs Single Bed
- Choose a single bed for younger kids, compact rooms, sleepouts and spare bedrooms.
- Choose a king single bed for growing kids, teenagers or single sleepers who want more comfort.
- Single beds save floor space, making them useful for small NZ bedrooms and shared kids’ rooms.
- King singles last longer for children moving into their teen years.
- For guest rooms, a king single can feel more comfortable than a single without taking as much room as a double.
- Measure first: make sure there is space for walking, drawers, wardrobe doors and a bedside table.

1. King Single vs Single Bed: What Is the Main Difference?
The main difference between a king single and a single bed is sleeping space. A single bed is smaller and easier to fit into compact rooms. A king single is longer and wider, giving more room for growing kids, teenagers and adults who want extra comfort.| Bed Size | Best For | NZ Bedroom Scenario |
|---|---|---|
| Single Bed | Younger kids, small rooms, shared rooms, spare spaces | Good for compact bedrooms where floor space matters |
| King Single Bed | Growing kids, teenagers, single adults, guest rooms | Good for more comfort without taking as much space as a double |
For many NZ homes, a single bed is the practical starter option. But if you want a bed that can last longer as a child grows, a king single bed may be the smarter choice.
2. When Should You Choose a Single Bed?

A single bed is usually the best choice when space is limited or when the room is for a younger child. It gives enough sleeping space for one person while keeping more floor area available for play, storage, study or movement.
A single bed works well for:
- Younger children
- Compact kids’ bedrooms
- Shared sibling rooms
- Small spare rooms
- Sleepouts or granny flats
- Rental bedrooms where flexibility matters
In Auckland apartments, townhouses and older NZ homes, bedroom space can be tight. A single bed can keep the room feeling more open, especially if you also need a wardrobe, drawers, desk or toy storage.
Homemart tip: If the room is small and your child still needs play space or study space, a single bed may be the more practical everyday choice.
3. When Should You Choose a King Single Bed?

A king single bed gives more sleeping space than a standard single, making it a strong option for growing kids, teenagers and single adults. It can feel more comfortable without taking up as much room as a double bed.
A king single bed works well for:
- Children moving up from a single bed
- Teen bedrooms
- Single adults in smaller rooms
- Guest bedrooms
- Family homes where the bed needs to last longer
- Rooms where a double bed feels too large
For NZ families, a king single can be a good middle ground. It gives a child or teenager more room to sleep comfortably, while still leaving space for bedside storage, drawers or a small desk.
If you are buying a bed frame for a child who is likely to use it for several years, a king single may offer better long-term value than buying a single now and upgrading later.
4. Which Is Better for Kids?
For younger kids, a single bed is usually enough. It saves space, fits easily into smaller rooms and leaves more floor area for toys, books and everyday movement. This is especially useful if two children share a bedroom.
For older kids or children who are growing quickly, a king single bed may be better. It gives them extra length and width, which can make the bed more comfortable as they move toward their teen years.
| Child’s Stage | Better Choice | Why |
|---|---|---|
| Younger child | Single bed | Saves space and suits smaller kids’ rooms |
| Growing child | King single bed | More space and better long-term use |
| Teenager | King single bed | More comfortable than a standard single |
| Shared room | Single bed | Keeps more space for two beds and storage |
5. Which Is Better for Teen Bedrooms?

For most teen bedrooms, a king single bed is the better choice if the room has enough space. Teenagers usually need more sleeping room than younger children, and a king single gives extra comfort without taking over the bedroom like a double bed might.
A teen bedroom often needs to fit more than just a bed. It may also need a study desk, drawers, bedside table, clothes storage and space for everyday items. A king single can offer a good balance between comfort and room function.
For smaller teen bedrooms, measure carefully before choosing. If a king single blocks the wardrobe or makes the room hard to move around in, a single bed may still be the better practical choice.
6. Which Is Better for Guest Rooms?
For guest rooms, a king single bed can be a useful upgrade from a standard single. It gives visitors more comfort while still taking up less space than a double or queen bed.
A king single works well if your guest room is also used as:
- A home office
- A kids’ study room
- A hobby room
- A storage room
- A spare room for occasional visitors
If the room is very small or rarely used by guests, a single bed may be enough. But if you often host family, friends or older children staying overnight, a king single can make the room feel more comfortable without using as much floor space as a double.
7. Which Is Better for Small NZ Bedrooms?
For small NZ bedrooms, the better choice depends on how much free space is left after the bed is placed. A single bed is easier to fit and leaves more room for storage, play or study. A king single gives more sleeping comfort but needs a little more floor space.Before choosing, check:
- Can the wardrobe door open properly?
- Can drawers open without hitting the bed?
- Is there enough room for a bedside table?
- Can someone walk comfortably around the bed?
- Does the room need a desk or storage unit?
In compact townhouses, apartments and rental bedrooms, a single bed can keep the layout easier to live with. But if the room has enough clearance, a king single can offer better comfort for long-term use.

| Choose This | If You Need |
|---|---|
| Single bed | A space-saving option for a younger child or compact room |

9. Do You Need Storage with a Single or King Single Bed?
Storage can make both single and king single beds more practical, especially in kids’ rooms and smaller NZ bedrooms. If the room has limited wardrobe space, a bed frame with storage or under-bed clearance can help reduce clutter.
Storage is useful for:
- Spare bedding
- Kids’ toys
- School items
- Seasonal clothes
- Guest linen
- Items not used every day
For a younger child’s room, storage can help keep toys and bedding tidy. For a teen bedroom, extra storage can help make space for study, clothes and personal items.
Final Thoughts: Should You Choose a King Single or Single Bed?
Choose a single bed if you need a practical, space-saving option for a younger child, compact bedroom, shared room or spare space. It is simple, flexible and easy to fit into many NZ homes.
Choose a king single bed if you want more comfort for a growing child, teenager, single adult or guest room. It can be a smart long-term choice when the room has enough space but a double bed feels too large.
The best option is the one that fits both the sleeper and the room. Measure carefully, think about how long the bed needs to last, and choose a size that keeps the bedroom comfortable and easy to use.
