Getting the single mattress dimensions right before purchasing prevents the most common buying mistakes. Whether you are buying for a child's room, a spare bedroom, or a solo adult, this guide gives you the precise measurements and practical guidance for Singapore.
Standard Single Mattress Dimensions in Singapore
A standard single mattress in Singapore measures 91 centimetres wide by 190 centimetres long.
This is the dimension used by most Singapore retailers and the size that standard single bed frames in Singapore are designed to accommodate. Bedding and mattress covers sold as single size in Singapore are made to these dimensions.
Super Single Mattress Dimensions in Singapore
A super single mattress in Singapore measures 107 centimetres wide by 190 centimetres long.
The super single is 16 centimetres wider than the standard single. Both sizes share the same 190-centimetre length. The additional width provides meaningfully more sleeping space for a solo adult or teenager.
Depth Dimensions
The third dimension, mattress depth, varies by construction. Standard single mattresses typically range from 15 to 22 centimetres in depth. Thicker hybrid or latex options can reach 25 centimetres or more.
Depth determines the total sleeping height when combined with the base, whether fitted sheets and protectors will fit correctly, and on bunk beds, whether the mattress is within the safe thickness range for the upper sleeping position.

How Singapore Single Sizes Compare Globally
Singapore single at 91 by 190 centimetres aligns closely with UK single at 91 by 190 centimetres and is slightly narrower than US twin at 97 by 190 centimetres.
Singapore super single at 107 by 190 centimetres is wider than a US twin at 97 centimetres and is equivalent in width to the New Zealand king single at 107 centimetres, though the NZ king single is 13 centimetres longer at 203 centimetres.
For most local purchases, Singapore standard dimensions are the relevant reference. When sourcing internationally, always confirm exact centimetre or inch dimensions rather than relying on size names.
Practical Checks Before Buying
Measure the internal dimensions of your bed frame. Confirm they match the mattress size you are ordering. Single at 91 centimetres and super single at 107 centimetres require different frames.
Note the mattress depth and confirm it falls within the pocket depth specified for any fitted sheets or covers.
For bunk bed upper bunks, check the frame's maximum recommended mattress depth specification before choosing.
