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.
While the sheets designed for full or double beds vary in size from brand to brand or even style to style, the mattresses they are designed to fit are all 54 inches wide, 75 inches long. A fitted sheet for a full or double bed closely matches the actual mattress size for a snug fit, while flat sheet sizes are larger. There is no standard measurement for a full or double flat sheet; in one brand, the sheet may be 81 inches wide, while another offers an 85-inch-wide flat sheet.
