King vs California King Mattress Sizes

If you're looking for the biggest mattress size around, then you've got two real options, king mattresses and California king mattresses. Though these two sizes are rather similar, there are a couple of things to consider before you commit to either one. Read on to find out about the differences between king and California king mattresses, and how the Cali kings got their interesting name.

What's the Main Difference Between King and California King Mattresses?

The key differences between a standard king and a California king bed are their measurements. The California king dimensions are 72"x 84", while the king size mattress dimensions are 76" x 80". California king mattresses are longer than a king by four inches, while the king models are wider by four inches.

Who Could Use a King Mattress?

If you sleep with a partner, or are just generally shorter, or average height, then you may prefer a king mattress over a California king. The extra width usually ends up being more convenient for the average person than the length. It may be easier to find box springs and bed frames for a king mattress, as it is the more common mattress type of the two.

Tall people might prefer the California king over the king mattress due to the extra length and leg room. If you have an awkwardly shaped bedroom, then a California king might fit better in your room than a king mattress would.

Even with size being the only major difference between the two mattresses, there are other things to be aware of when you're mattress shopping. You're going to want to find a mattress that is tailored to your preferences in terms of firmness and material. King mattresses come in any firmness level and many styles. You'll be able to find king innerspring, king hybrid, and king memory foam mattresses with relative ease. You'll also have an easy time finding king mattresses in a variety of firmness levels, so you can find one that fits your personal sleep preferences. California king mattresses tend to have less options available when it comes to mattress type and firmness levels since they are generally more rare than king mattresses. Though you should still be able to find enough options to suit you. To get even more tips for choosing a new mattress, check out our mattress buying guide.

The origin of the California king namesake is uncertain. It most likely originated on the west coast of the USA sometime around the mid-20th century. Before they garnered more popularity across the nation, you would only really find anyone using one of these mattresses in California. It's also said to be more accommodating to the large homes that you might find in the wealthier areas of the Golden State. They gained their status as a luxury item due to their popularity among celebrities who live in Cali. Though its true origins aren't very clear cut, these mattresses maintain their reputation as a luxury item even now.
