Choosing the right mattress size is about more than fitting a bed into your bedroom. You need enough sleeping space, a mattress that matches your bed frame and room to move comfortably around the furniture.
If you are comparing mattress sizes in the UAE, names such as single, queen, king and super king can be confusing. Retailers may use different regional naming systems, so two mattresses called “king size” may have different measurements.
This guide explains the dimensions to check, how to measure your bed and what to consider before ordering your next mattress.
UAE Mattress Size Chart
The chart below shows size options listed for Ruby’s Cool Max Mattress. All dimensions are width × length in centimetres. Availability varies by model, so always check your chosen product’s size selector before purchasing.
| Dimensions | Label on Ruby’s Size Selector | Space to Consider |
|---|---|---|
| 90 × 200 cm | EU Single | A compact option for one sleeper |
| 120 × 200 cm | Wide Single | Additional width for one sleeper |
| 140 × 200 cm | EU Double | A wider solo bed or compact shared option |
| 150 × 200 cm | USA Queen / UK King | A shared bed where room space is limited |
| 160 × 200 cm | EU King Size | More width for shared sleeping |
| 180 × 200 cm | UK Super King | A spacious shared sleeping surface |
| 200 × 200 cm | UK Emperor | An extra-wide option for larger bedrooms |
Buying tip: These are product size labels, not a universal UAE sizing standard. Match the centimetre measurements to your bed frame rather than ordering by the size name alone.
Single Mattress: A Practical Choice for One Sleeper
A 90 × 200 cm mattress provides a compact sleeping surface for one person. It can work well in smaller bedrooms, children's bedrooms and guest rooms with separate beds.
For someone who likes more space to stretch or turn, a 120 × 200 cm wide single adds 30 cm of width while keeping the same length.
- Consider 90 cm width when floor space is a priority.
- Compare 120 cm width if one sleeper prefers additional room.
- Check the bed frame dimensions before moving between sizes.
Queen Mattress: Check the Exact Measurements
Queen is a familiar shopping term, but its dimensions depend on the retailer and sizing system. Ruby’s referenced size selector labels 150 × 200 cm as “USA Queen / UK King.”
A mattress of this width can be an option for couples furnishing a smaller bedroom or for one person who enjoys a larger bed. When shared equally, each sleeper has approximately 75 cm of width.
Before choosing, consider how much you both move during sleep and whether the bed leaves enough space for wardrobes, bedside tables and daily movement.
King Mattress: More Width for Shared Sleeping
Ruby’s referenced size selector labels 160 × 200 cm as “EU King Size.” This provides 10 cm more total width than a 150 × 200 cm mattress.
When comparing a queen and king mattress, check the actual difference in centimetres. A larger size name does not tell you exactly how much additional sleeping space you will receive.
A wider mattress may appeal to couples who prefer more individual space, provided the bed frame and bedroom can accommodate it.
Super King Mattress: A Spacious Bedroom Option
A 180 × 200 cm mattress, labelled “UK Super King” on the referenced Ruby product, provides approximately 90 cm of width per person when shared equally.
Compared with a 150 × 200 cm mattress, it adds 30 cm of total width. That extra space can be useful for couples who like to stretch out or prefer more separation while sleeping.
Remember that the complete bed will usually occupy more floor space than the mattress itself, especially with an upholstered frame or a wide headboard.
What About a 200 × 200 cm Mattress?
A 200 × 200 cm mattress offers a square sleeping surface and is labelled “UK Emperor” on Ruby’s referenced size selector. It is worth considering when you want additional width and have a suitably spacious bedroom.
Check the availability of correctly sized fitted sheets, protectors and bedding before choosing an extra-wide mattress.
How to Measure Your Bed for a New Mattress
- Remove the bedding: Make the mattress platform or internal frame edges accessible.
- Measure the internal width: Measure across the space where the mattress will sit, rather than across the outside of the bed frame.
- Measure the internal length: Measure from the head end to the foot end of the mattress space.
- Check the required thickness: Consider the frame depth, headboard height and your preferred total bed height.
- Confirm the fit: Compare your measurements with the bed manufacturer's requirements and your selected mattress option.
If your existing mattress has lost its shape, avoid using it as the only measurement reference. Check the bed frame itself and contact the retailer if the dimensions are unclear.
How to Choose a Mattress Size for Your Bedroom
Measure the Complete Bed Frame
Use the bed’s external dimensions when planning your room layout. Thick side rails, curved upholstery and extended headboards can make the frame considerably larger than the mattress.
Allow Space for Everyday Movement
Check that you can walk around the bed, open wardrobe doors and pull out drawers. Marking the proposed bed footprint on the floor can help you visualise the space before buying.
Consider Both Sleepers
For a shared bed, discuss comfort preferences together. Mattress width affects personal space, while construction and firmness affect how the bed feels. A larger mattress will not automatically resolve an unsuitable firmness or support system.
Check Length as Well as Width
Taller sleepers should check that the mattress provides comfortable space beyond their height. Moving from a narrower to a wider 200 cm-long mattress does not add length.
Plan the Delivery Route
Measure doorways, stairs, lifts and tight turns. Ask how your selected mattress is packaged and whether it can pass through your building’s access points.
Common Mattress Size Mistakes to Avoid
- Ordering by “queen” or “king” without checking centimetres.
- Measuring the outside of the frame instead of the mattress space.
- Choosing a larger bed without allowing room for doors and drawers.
- Forgetting to check mattress thickness and fitted-sheet depth.
- Assuming every mattress model is available in every size.
Frequently Asked Questions
Are mattress sizes standard across the UAE?
You may encounter different regional naming systems when shopping. Always use the stated width and length to confirm compatibility with your bed.
What is the difference between 160 × 200 and 180 × 200 cm?
The 180 × 200 cm option is 20 cm wider. Both have the same length. For two sleepers sharing equally, the wider option adds 10 cm of sleeping width per person.
Will a new king mattress fit my existing king bed?
Only if the actual measurements match the bed’s requirements. The word “king” alone is not enough to confirm the fit.
Does a bigger mattress feel softer?
Size and firmness are separate choices. Compare the mattress materials, comfort layers and listed firmness alongside its dimensions.
