Generally no, but it could! If you are single, then a twin or other size of smaller bed would save you money. However, if you are a couple, or if you want to impress or hope to have a partner then much depends on your height and width. The King gives you 4 inches more in width while the Cal King gives you 4 inches more in length. That’s when the size of your bedroom might matter. The California King is 72” wide and 84” long, while the Standard King is 76” wide and 80” long. You also have to take any other furniture in your bedroom into consideration.
