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.

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.
