Getting the measurements right before buying a single bed mattress is a straightforward but important step. Whether you are buying for a child's room, a guest bedroom, or a solo adult sleeper, the dimensions need to match the frame, the room, and the bedding you plan to use.
Key Single Bed Mattress Measurements in Singapore
A standard single mattress in Singapore measures approximately 91 centimetres wide by 190 centimetres long by approximately 15 to 22 centimetres deep for most standard constructions.
A super single, the next size up, measures approximately 107 centimetres wide by 190 centimetres long. The depth range is similar.
These three measurements, width, length, and depth, together determine what frame the mattress fits, whether your bedding will fit correctly, and what the total sleeping height will be when the mattress is placed on a base.
Width: The Primary Differentiator
The 91-centimetre width of a standard single is comfortable for one person in a children's room or smaller bedroom. It is also the size used in most bunk beds and trundle beds.
The 107-centimetre super single provides more room for a solo adult sleeper and is increasingly popular for teenagers who have outgrown the standard single width. In a room where a wider single size is practical but a full double or queen is too large, the super single provides a well-proportioned middle ground.
Confirm which specific width your bed frame is designed for before ordering. Standard single frames and super single frames are not interchangeable.
Length: Consistent Across Single Sizes
Both standard single and super single mattresses in Singapore are 190 centimetres long. This accommodates most adults comfortably up to approximately 180 to 185 centimetres in height.
For taller individuals above 185 centimetres who need a single-width sleeping surface, enquiring about longer custom dimensions or considering a larger size may be worth exploring.
Depth: Affects Fit, Height, and Compatibility
The depth of a single mattress, typically 15 to 22 centimetres for standard constructions, affects three practical aspects.
Total sleeping height: the mattress depth adds to the base height to produce the final sleeping surface height. For a child's bed, a lower total height is generally safer. For an adult, a height around knee level is most comfortable for getting in and out.
Bedding fit: fitted sheets are designed with a pocket depth that must match or exceed the mattress depth. A sheet with a 20-centimetre pocket will pull off a 25-centimetre mattress. Check pocket depth against mattress depth before purchasing bedding.
Bunk bed compatibility: upper bunk positions typically specify a maximum mattress depth of 15 to 20 centimetres for headroom and guardrail safety. Confirm the frame specification before choosing.
Using Measurements Confidently
With the three measurements in hand, checking frame compatibility, calculating total sleeping height, and matching bedding specifications becomes straightforward. Taking five minutes to do these checks before placing an order prevents the most common fitting problems.

Frequently Asked Questions
What are the single bed mattress measurements in Singapore?
Standard single: approximately 91 centimetres wide by 190 centimetres long. Super single: approximately 107 centimetres wide by 190 centimetres long. Depth varies by construction, typically 15 to 22 centimetres.
Why does mattress depth matter for a single bed?
It determines the total sleeping height when combined with the base, whether fitted sheets and protectors will fit properly, and on bunk beds, whether the mattress is within the safe thickness range for the upper bunk.
What measurements do I need before buying a single mattress?
The internal width and length of your bed frame, the recommended or maximum mattress depth for the frame if using a bunk, and the pocket depth of any fitted sheets you plan to use.
Is a super single much bigger than a standard single?
In width, it is 16 centimetres wider at 107 versus 91 centimetres. In length and depth range, the two sizes are the same. The difference in width is noticeable for a solo adult sleeper who moves during the night.
Do standard single and super single need different frames?
Yes. Each size requires a frame designed for its specific dimensions. A super single mattress will not fit correctly in a standard single frame.
What depth single mattress suits a children's bunk bed?
Most bunk frames specify 15 to 20 centimetres as the maximum depth for the upper bunk. Check the frame's specifications before choosing. A thinner mattress in this range maintains adequate headroom and proper guardrail safety.
