Why Buy a California King Bed?
- You're Very Tall. The California King is the longest bed available and is the best option for very tall people. My husband, who is 6'7", would have to sleep diagonally on a Standard King but can sleep straight on our California King.
- You have a Long and Narrow Room. Some rooms that may not comfortably hold a Standard King could hold a California King.
Why Buy a Standard King Bed?
- More Space to Spread Out. Unless you're very tall, most people opt for the Standard King, since extra width is preferable to extra height.
- Bedding is Easier to Find. Standard Kings are more popular and so you have more options for bedding. Also, while fitted sheets are made in California King size, flat sheets and blankets are not, meaning they may be a bit too short.
Should I buy King or Cal King Sheets?
When you buy sheets for your King mattress, make sure you buy the correct size. Your flat sheet can fit both the California and the Standard King, but the fitted sheet needs to fit your specific mattress size.
Unless you're very tall, most people go with the Standard King bed. Bedding is easier to find and the extra width is preferential over the extra length.

Questions & Answers
I think I have a California king bed frame. Can I put a regular king mattress on it?
If you have a metal, adjustable bed frame, you should be able to use a Cal king or Eastern king mattress (and in some cases, a queen will even work). However, if you do not have an adjustable frame, a Cal king bed frame needs a Cal king mattress. Cal king bed frames are longer and not as wide, so using a king mattress will cause sagging on the ends, which will end up damaging the mattress.
I just bought a Cal king bed, and it needs two twin box springs. Does it need XL box springs or will regular twin box springs fit?
Unfortunately, twin box springs will not work on Eastern king or California king mattresses. A regular twin is 38X74 inches long and the long twin is 38X80 inches long. A Cal king bed is 72X84 inches. Two long twins together would be 76X80 (too wide and too short.) You need to buy a box spring for the specific mattress. A king box spring will likely come in two pieces, but it shouldn't be confused with twin box springs.
