The California king is a mattress size specific to the United States market. If you have encountered the term while researching mattress options, understanding what it is and how it relates to Singapore sizing helps you navigate the comparison clearly.
California King Dimensions
A California king mattress measures 183 centimetres wide by 213 centimetres long, or approximately 72 inches wide by 84 inches long.
It is the same width as a standard US king but 23 centimetres longer. This extended length makes it well-suited to very tall sleepers, particularly those above approximately 190 centimetres in height, for whom the extra length provides meaningful additional sleeping space.
How California King Compares to Singapore King
A Singapore standard king mattress measures approximately 183 centimetres wide by 190 centimetres long.
The California king is identical in width to a Singapore king at 183 centimetres. The length is significantly different: the California king is 213 centimetres long compared to Singapore's 190 centimetres, a difference of 23 centimetres.
This means California king length provides substantially more room for tall sleepers than Singapore's standard king. However, California king frames and bedding are not the same as Singapore king specifications.
Is the California King Available in Singapore?
The California king is a US-specific size and is not a standard stocked size in Singapore's mattress market. Singapore retailers stock Singapore standard dimensions, and California king frames, mattresses, and bedding are not readily available locally.
For a very tall sleeper in Singapore who needs more than 190 centimetres of mattress length, the practical options are to enquire with Singapore retailers about custom or non-standard length mattresses, or to consider a European king at 180 by 200 centimetres as a closer locally-accessible alternative for additional length, though still shorter than a California king.
Most tall sleepers up to approximately 190 to 195 centimetres find a Singapore standard king at 190 centimetres adequate with room to spare.
For Most Singapore Buyers
The Singapore standard king at 183 by 190 centimetres serves the needs of most couples well. For extremely tall sleepers who find 190 centimetres insufficient, discussing options with a Singapore retailer is the most practical first step.
