A California King Bed is a large mattress size designed for taller individuals or those who prefer extra legroom. It measures 72 inches wide by 84 inches long, making it longer than a standard King Bed, which is 76 inches wide and 80 inches long. This extra length provides more space for stretching out comfortably. Due to its size, a California King Bed is ideal for spacious bedrooms. It often requires larger bedding and accessories, such as sheets and comforters, specifically designed for this size. Many people choose this option for its combination of width and length, catering to various sleeping preferences.
