A king flat sheet is about 100 inches (280cm) across and is made with a centre panel of about 66 inches (193cm) and two side panels of 17 inches (43cm) panels each. The seams fall along the right and left side running very close to the edge of the mattress.

PRO-TIP: When you make the bed, put the flat sheet on “upside down” with finished side facing down and the back side of the sheet facing up with your duvet cover on top. Then you’ll be sleeping between the two finished sides of the sheets.
