What is the difference between a California King and a Standard King Mattress?

The California King, sometimes called a Western King, is longer and narrower than the Eastern King, usually referred to as a King or Standard King.

The Standard King is 4" wider while the California or Western King is 4" longer.

Both sizes come with two box springs and one mattress.

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.

        I have two, crib to college, full size, sleigh beds purchased in California. They had mattresses and box springs that fit in 2005. The beds have been in storage for 6 years and now they have been shipped to Virginia and put together. The new mattress DO NOT FIT! Is there a difference in full size beds. I need 51-1/2 " all the charts show 54'. Can anyone tell me where I cn get a 51 to 51-1/2 inch box spring and possibly mattress.

        I can't find (non-Cali) King sheets anywhere! I've looked at Costco and Target and they both have all sizes except King. They don't even have price tags for King size (meaning, they're not out of stock). What the heck!!

        So, if the mattresses are exactly 4 inches different each way, cant you just rotate the mattress on the frame to change it from a king to a california king?

        I have been searching the internet for a cotton California King blanket. The king blankets just aren't long enough if you have a thick mattress. Does anyone know of a manufacturer who actually makes California king blankets (not comforters or duvet covers, just blankets)? Thanks!

        Great. This is my first time to visit your site. You've done an informative article. I agreed that organic baby crib mattress is really safety. Maybe next time I will purchase an organicmattress soon. Thanks for the information.

        If you really want the ultimate you can look into the Grand King by sleep number. It measures 80X98 inches!!! It used to be hard to find bedding for it even through sleep number but it seems that bedding is becoming more available. The salesman in the sleep number store told me that macys will soon be offering bedding for this HUGE bed.

        I had no idea that a regular King was wider than a Cal King! Thanks for sorting out my confusion.

        Hmm...I have a california king, I thought that it was wider, but am finding out that it is actually longer, I have just been sleeping on it wrong. Oh well.. I like it

        Thanks for the info, I didn't realise the subtle difference in the sizes of the 2 mattresses. I'm in the UK and we sleep on what we call a 'super-king' sized bed which I thing is the same as an Eastern King.

        Unless you are very tall, The wider bed is always the better option IMHO......

        Thanks, James. I'm surprised you're not in an extra long twin. I know there are a few in the family. ;) Paul and I slept in a Queen for years. It was quite snug. xo R

        Glad to see you hubbing again Rob.I will never get confused about king size beds again!

        Right now, I sleep on a full, and let me tell you, for someone 6'6", it's far too small.

        I think you're right, George. It's a lot easier to find California King bedding on the West Coast. I actually prefer the Cal King because of the length, but I've heard from friends on the East Coast that they've never heard of a Cal King. Interesting. Thanks for the comment!

        Robin, this is so good. It has been my experience that the California King (or Western King) is much more available in (surprise!) California. Years ago, Eastern King sheets were not even carried in the stores I shopped in. Both sizes of sheets are widely available now, and since many people shop online (accessible to the whole country) both sizes are marketed.
