A single bed typically measures about 90 cm (3 feet) wide and 190 cm (6 feet 3 inches) long. This size is standard in many places, including the UK, and is suitable for one person. In the US, a similar size is called a twin bed and usually measures 38 inches (about 97 cm) wide by 75 inches (about 191 cm) long. Both terms—single and twin—refer to roughly the same mattress size, ideal for solo sleepers or smaller bedrooms. For additional variants:
- A small single bed is narrower, about 75 cm wide.
- A long single bed might be slightly longer, about 203 cm.
Thus, a standard single bed is approximately 90 cm by 190 cm (3 feet by 6 feet 3 inches).
