Mattress dimensions in Singapore are typically given in centimetres, but if you are more familiar with inches or are comparing sizes across different regional standards, having a clear reference in inches is a useful practical tool.
Single Mattress Dimensions in Inches: Singapore Standard
A standard single mattress in Singapore measures approximately 91 centimetres wide by 190 centimetres long.
Converting to inches: 91 centimetres is approximately 35.8 inches, and 190 centimetres is approximately 74.8 inches. In rounded practical terms, a Singapore single mattress is approximately 36 inches wide by 75 inches long.
A super single in Singapore measures approximately 107 centimetres wide by 190 centimetres long, which converts to approximately 42 inches wide by 75 inches long.
Mattress depth varies by construction, typically from 15 to 22 centimetres for standard options, which is approximately 6 to 8.7 inches.
How Singapore Single Compares to US and UK Single in Inches
The US twin size, which corresponds to a standard single, measures 38 inches wide by 75 inches long. The Singapore standard single is very close at approximately 36 inches by 75 inches, with a 2-inch width difference.
The UK single measures 36 inches wide by 75 inches long, which is essentially the same as Singapore's standard single.
For most practical purposes, Singapore single mattress dimensions in inches align closely with UK single sizing and are very close to US twin sizing. Bedding sourced from the UK in single size will generally fit a Singapore single mattress without significant issues.
For US twin XL, which measures 38 by 80 inches, both the width and length differ slightly from Singapore's single. The extra length of US twin XL at 80 inches is approximately 203 centimetres, compared to Singapore's 190 centimetres.
Using Inches for Practical Checks
Confirming that your bed frame's internal dimensions in inches match the mattress you are ordering prevents fitting problems. If your frame is specified in centimetres, convert to inches as needed or simply use centimetres throughout for consistency.
When sourcing single bedding or a mattress protector from an international retailer, confirming the product is designed for approximately 36 by 75 inches (Singapore standard single) or 42 by 75 inches (Singapore super single) ensures a proper fit.
