A full size bed is also known as a double bed. The sheet measurements vary slightly between US and UK.  In the US a flat sheet for a full size bed would be 221cm x 259cm. A fâ¦itted sheet would be 137cm x 193cm x 20cm.  In the UK a flat sheet would be 220cm x 260cm and a fitted sheet would be 135cm x 190cm x 20cm.
Save. The most important difference between twin beds and full beds is width. Each is 75 inches long, but full beds are 54 inches wide while twin beds are 39 inches wide. The key question is, Do you need more space in the room or more space on the bed?
