A California King blanket is specifically designed to fit a California King bed, which measures 72 inches wide by 84 inches long. These blankets are larger than standard king-size blankets, providing ample coverage for taller individuals or those who prefer extra space. Typically, California King blankets come in various materials, including cotton, fleece, and down, catering to different preferences for warmth and comfort. When shopping for one, it's essential to check the dimensions to ensure a proper fit, as they can vary by manufacturer.
