A single bed fitted sheet is designed to fit a standard single mattress, which typically measures 39 inches by 75 inches (approximately 99 cm x 190 cm), though dimensions can vary slightly by region (e.g., a UK single is 90 cm x 190 cm). It features the same elasticated skirt construction as larger fitted sheets, engineered to hug the smaller mattress dimensions perfectly. This ensures the sheet remains smooth and secure, providing a comfortable sleep surface without slipping or bunching, which is particularly important for solo sleepers, including children and adults. The application is widespread in children's rooms, dormitories, studio apartments, and guest rooms. For a child's bed, a single fitted sheet in a fun pattern or a soft, durable fabric like brushed cotton can make the bed comfortable and inviting. Its ease of use is a significant benefit for parents during frequent bedding changes. In a dorm room, a student might prioritize a fitted sheet made from wrinkle-resistant and easy-care microfiber to minimize maintenance. The key consideration is mattress depth; while many single mattresses are standard depth, some bunk bed or trundle bed mattresses may be thinner, requiring a shallower pocket. Conversely, thicker single mattresses need a deep-pocket design.
