King vs California King Size Mattresses

What is the difference between a standard king vs. California king?

The main difference between these two sizes is the dimensions. A standard king, otherwise known as Eastern king, is 76 inches by 80 inches long. A California king measures 72 inches wide by 84 inches long. This makes it longer and narrower than a standard king.

While every mattress is made in a king-size, not every mattress is available in a California king size. Additionally, the standard king has more options for bedding accessories. Things like box springs, sheets, adjustable bases, and comforters.

Which size is the best for you?

The California king bed is the longest of the standard mattress sizes. It's intended for tall people who want to ensure their feet don’t hang off the bed. If you’re over 6' 2", then you’ll probably want the California king size for the extra length. Shop California King Size Mattresses

The king-size bed is the widest of the standard mattress sizes. It gives you extra shoulder room to sleep comfortably with your partner. The extra width of a king mattress would give you all the space you need. People who have kids or pets joining them in bed may also find the wider size preferable. Shop King Size Mattresses
