A California king size bed is a mattress that measures 72 inches wide and 84 inches long. It is best suited for taller individuals or for narrow bedrooms where its more slim profile will fit in better aesthetically. The California king is longer than a standard king, but it is less wide, and has less surface area overall. It is a great option for tall people, couples, and pet owners who share the bed with animals, as its extra length allows pets to sleep at the foot of the bed without disturbing the sleepers. The California king size bed is also preferred by NBA players who need longer than standard size mattresses to support their height and body weight for a good night’s sleep. It is important to note that a California king size bed is not only longer but also wider than a queen size mattress, and it is recommended for master bedrooms measuring at least 12 feet by 14 feet to accommodate its extra length.
