The other common sizes in North America are extra-long twin, full and king. Fitted extra-long twin sheets measure 39 by 80 inches, fitted full sheets measure 54 by 75 inches, and fitted king sheets measure 76 by 80 inches. Some mattress manufacturers produce a California king size that takes a 72-by-84 inch fitted sheet. Fitted sheets should fit as closely to the mattress as possible and need to be sized for the correct depth of pocket as well as the area of the mattress. Mattresses range in depth from 10 to 18 inches.
