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.
So planning a bed linen purchase necessitates knowing the dimensions of the linens made for standard-size mattresses, such as flat sheets, so you can buy those that fit. A twin fleet sheet measures roughly 70-by-100 inches, give or take a few inches. A full-size flat sheet measures roughly 85-by-100 inches.
