Compare this to standard size sheets, which typically have a side depth of anywhere from 7 to 14 inches. Our Supima cotton GhostSheets, for example, measure 60” x 80” x 15” for the queen size. How Deep Are Deep Pocket Sheets?ĭeep pocket fitted sheets typically start at around 15 inches on the sides, but can go as high as 22 to 24 inches, depending on the manufacturer. The excess fabric also means they’re less likely to pop off when you move around. If you’re buying a mattress that is 12” profile or higher, you’ll likely want deep pocket sheets so you won’t have any trouble getting your fitted sheet to wrap around the edges of it. Deep pocket sheets are specifically designed to cover mattresses with additional loft and comfort layers, like those in the GhostBed collection.
