Knowing the single bed mattress size in centimetres before purchasing is the most reliable way to ensure a proper fit with your frame, your bedding, and your room layout. This guide provides the exact dimensions and explains what they mean in practice.
Single Bed Mattress Size in CM: Singapore Standard
A standard single bed mattress in Singapore measures 91 centimetres wide by 190 centimetres long.
These are the dimensions used by most local retailers and the size that standard single bed frames in Singapore are designed to accommodate. Bedding, mattress covers, and protectors sold as single size in Singapore are specified for these dimensions.
A super single mattress, the next size up, measures 107 centimetres wide by 190 centimetres long. The extra 16 centimetres of width provides meaningfully more sleeping space for a solo adult.
The Third Dimension: Mattress Depth in CM
Beyond width and length, mattress depth in centimetres matters for three practical reasons.
For frame compatibility, particularly bunk beds: most bunk bed upper bunks specify a maximum mattress depth of 15 to 20 centimetres. Exceeding this reduces headroom and may affect guardrail safety.
For total sleeping height: the mattress depth adds to the base height to determine the final sleeping surface level. A 20-centimetre mattress on a 35-centimetre divan produces a 55-centimetre total height, which is comfortable for most adults.
For bedding fit: fitted sheets specify a pocket depth that must match or exceed the mattress depth. A sheet with a 20-centimetre pocket will not fit a 25-centimetre mattress.
Standard single mattresses typically range from 15 to 22 centimetres in depth. Thicker options are available in some constructions.
Converting to Other Units
For buyers more comfortable in other units: 91 centimetres is approximately 35.8 inches or 2 feet 11.8 inches. 190 centimetres is approximately 74.8 inches or 6 feet 2.8 inches.
In practical terms, a standard single mattress is very close to 3 feet by 6 feet 3 inches. A super single is approximately 3 feet 6 inches by 6 feet 3 inches.
Checking Measurements Before Purchasing
Three checks before placing an order prevent common fitting problems.
Measure the internal dimensions of your bed frame. Confirm they match the mattress you are ordering. Single at 91 centimetres and super single at 107 centimetres require different frames.
Note the mattress depth and check it against the pocket depth of any fitted sheets or mattress protectors. A cover designed for up to 25 centimetres will not fit a 30-centimetre mattress.
For bunk beds, check the frame's maximum recommended mattress depth before choosing.

Standard single: 91 cm wide by 190 cm long. Super single: 107 cm wide by 190 cm long. Depth varies by construction, typically 15 to 22 cm.
Is there a size difference between Singapore single and other countries?

What is the super single size in cm in Singapore?
107 cm wide by 190 cm long. The extra 16 cm of width compared to a standard single provides more sleeping space for a solo adult.
What cm pocket depth do I need for single bed sheets?
For a mattress of 18 to 20 cm depth, sheets with a 25 cm pocket depth fit well. For thicker mattresses approaching 25 cm, sheets with a 30 cm pocket depth provide a more secure fit.
What single mattress depth suits a bunk bed upper bunk?
Most bunk frames specify a maximum of 15 to 20 cm. Check your frame's specifications. A mattress within this range maintains adequate headroom and guardrail safety.
How do I measure my bed frame before buying a single mattress?
Measure the internal width and length of the sleeping platform with a tape measure. Compare these against the mattress dimensions. For a snug fit, the internal frame dimensions should be within one to two centimetres of the mattress dimensions.
