That depends on the size of your bedroom. If your master is 12 by 12 or 12 by 14 feet, you could go with a California king or a regular king. However, if you’ve got an even bigger room you need to fill out, you might consider one of the oversize king beds. Wyoming kings will still fit in a 12 by 12-foot room for those who just want a giant bed. However, Texas kings need a room of no less than 12 by 14 feet, and Alaska kings can’t fit in a room of less than 16 by 16 feet.
