Choosing between a King and Queen size bed can seem straightforward, but those extra centimetres can make a noticeable difference to both your sleeping space and the way your bedroom functions.
In Singapore, a Queen mattress measures 152 cm x 190 cm, while a King measures 183 cm x 190 cm. Both provide the same length, but a King offers an additional 31 cm of width. The right choice depends on more than simply choosing the largest mattress your room can accommodate. Consider who shares the bed, how much personal sleeping space you prefer, your bedroom layout and any additional furniture you wish to include in the space.

What is the difference between a Queen and King size mattress?
The main difference between a King size mattress and a Queen is width. In Singapore, these beds are the same length (at 190 cm), but a King is 31 cm wider. That means a King provides around 20% more mattress surface area than a Queen. When divided between two sleepers, each person gains approximately 15.5 cm of additional width. This can be significant if you or your partner prefer to spread out, regularly change sleeping positions or simply value having a little more personal space.
If you are still deciding which mattress dimensions best suit your space, our mattress size guide compares the full range of standard mattress sizes in Singapore.
| Mattress size | Dimensions (cm) | Dimensions (in) | Best for |
|---|---|---|---|
| Queen | 152 x 190 cm | 60 x 75″ | Single adults and couples in a small room |
| King | 183 x 190 cm | 72 x 75″ | Couples and those who sleep with children or pets |
It is important to remember that mattress dimensions differ internationally. US King and Queen mattresses, for example, use different dimensions from those commonly sold in Singapore. When purchasing a mattress, bed frame or bedding, always check the manufacturer’s stated dimensions rather than relying on the size name alone.
How big is a Queen size bed in Singapore?
A standard Queen size mattress in Singapore measures 152 cm wide by 190 cm long. For one person, this provides a generous amount of room to stretch out. For couples, dividing the mattress evenly provides approximately 76 cm of sleeping width per person.
A Queen can be particularly practical when you want a comfortable bed for two while preserving more of the surrounding floor space. Its smaller footprint allows for wider walkways and more room for bedside tables, wardrobes or other furniture, making it easier to accommodate in smaller Singapore bedrooms where space may be at a premium.
Remember that the dimensions refer to the mattress itself. Your complete bed setup may have a larger footprint depending on the foundation, bed frame, headboard and surrounding upholstery.
How big is a King size bed in Singapore?
A standard King size mattress in Singapore is 183 cm wide by 190 cm long. The additional width is its defining advantage over a Queen, as two people sharing the mattress have approximately 91.5 cm each if the bed is divided evenly. A King size bed is worth considering if both partners prefer more room, one or both sleepers tend to spread out, or children or pets occasionally join you in bed.
The trade-off is its larger footprint. A King takes up more floor area at mattress level than a Queen, even before the bed frame and any additional furniture are taken into account. Bedding accessories (such as pillows, sheets and mattress protectors) also tend to be more expensive for larger sizes, and this may factor into your choice of King vs Queen.
How to choose between a King and Queen size bed
There is no single answer that suits every bedroom. The right choice depends on how much space you have available, how much room you prefer while sleeping and how the bed will fit alongside the rest of your furniture. Practical considerations such as the dimensions of your bed frame and your overall budget can also influence whether a King or Queen is the better fit for your home.
Measure your available floor space
Before choosing a King or Queen size, make sure the whole bed will fit comfortably in your space, including your bed frame and headboard. Start by measuring the area where the complete bed will sit.
Check whether you can comfortably:
- Walk safely around the sides and foot of the bed
- Open doors, drawers and cupboards fully
- Accommodate your preferred bedside tables or dressers
- Reach power points and switches with ease
- Move the mattress and bed frame into the room in the first place
- Rotate the mattress regularly according to mattress care guides
One simple way to compare a Queen and a King size bed is to mark both footprints on your bedroom floor with painter’s tape. Start with a 152 x 190 cm Queen, then extend the width to 183 cm to represent a King. Place your bedside tables where they would normally sit and check how easily you can move through the room. This gives you a much clearer impression of whether the extra 31 cm feels luxurious or simply makes the bedroom feel crowded and impractical.
Keep in mind that bed frames and headboards will add to these dimensions, especially frames with integrated storage (such as drawers) which can extend the usable size of the bed well beyond the mattress. Check the external dimensions of your chosen bed frame before determining whether a King or Queen will fit.
Consider who will be sleeping in the bed
Think about who will regularly be using the bed, or which room it is intended for. A Queen provides generous space for a solo sleeper while comfortably accommodating many couples, making it a versatile choice for both main bedrooms and guest rooms. For a guest bedroom, a Queen can be particularly practical, offering enough space for either one or two guests without taking up as much of the floorplan.
For solo sleepers, a King offers considerably more room to stretch out, although you may find that it provides more sleeping space than you need. For couples, however, the additional width can be valuable, especially if either person tends to spread out, frequently changes position or simply prefers more personal space. A King can also provide greater flexibility for families where children or pets occasionally join the bed.
Work within your overall budget
The mattress itself is not the only cost to consider. Moving from a Queen to a King may also mean purchasing a larger bed frame or foundation, mattress protector and bed linen, with King-size mattresses and accessories generally costing more than their Queen-size equivalents. It is therefore worth considering the cost of your complete sleep setup rather than comparing mattress prices alone.
At Sealy, our mattresses are available across a variety of price points, from more affordable options through to luxury collections, with different sizes to suit your space and budget without compromising on support, quality or comfort.
Is a King bed worth upgrading from a Queen?
If you already sleep on a Queen, the most noticeable change when moving to a Singapore King is the additional 31 cm of width. The length remains unchanged. For couples, this effectively adds about 15.5 cm of space per sleeper.
An upgrade may therefore be ideal if your existing Queen feels restrictive and your bedroom can accommodate a wider bed without impacting movement or furniture placement. If you are already comfortable on a Queen, however, a larger mattress is not inherently necessary. Keeping the smaller footprint may give you greater flexibility elsewhere in the room.
Does size affect comfort and support?
Size and mattress quality are separate considerations. Choosing a King instead of a Queen gives you more sleeping surface, but it does not automatically make the mattress more comfortable or supportive. Factors such as mattress construction, comfort preference and targeted support should also form part of your decision. At Sealy, a Single mattress offers the same orthopaedic support and pressure relief as a King within the same range, so that sleepers of all ages and sizes may enjoy the same benefits of deep, refreshing sleep.
This means the comparison is really a two-stage process: first determine which size suits your room and sleeping arrangements, then select a mattress within that size that provides the comfort and support you prefer. Where possible, try different mattresses in person to determine whether the size, support and comfort levels are right for you.
