The California King is the longest standard bed size available, ranging from 74" to 77" wide by 86" to 89" long, and is the preferred choice for taller sleepers, larger master bedrooms, and anyone who has always felt a standard king falls just a little short. Four inches narrower than a standard king but four inches longer, a California King bed frame suits elongated bedroom layouts particularly well and gives taller sleepers the legroom a standard King simply does not provide. Worth noting for shoppers transitioning from a standard King, California King bedding is sized differently and is not interchangeable, so it is worth planning for that when making the switch. Shop our full collection and find the California King bed frame that works for your space.
