A queen-size bed is 60 inches wide and 80 inches long. These dimensions are 6 inches wider and 5 inches longer than a double or full-size bed.
Queen-size beds take queen sheets. The fitted sheet is 60 by 80 inches to fit the mattress tightly. The flat sheet is 90 inches by 102 inches to allow for some overhang. Queen beds can take full/queen comforters, which are 86 by 86 inches and designed to fit beds of both sizes.
Beds labeled Olympic, super or expanded queen are 6 inches wider than standard queen beds. However, these sizes are rare in the United States.
