California King vs. King Mattress – Dimensions


You may ask, why are California King bed vs Regular King different from each other? Well, it all starts and ends in their dimensions and overall constructions.

The main difference is that a King size is wider with 76 inches of width, while a Cal King has only 72 inches. Similarly, the Cal King is longer with 84 inches in length, while the standard King has 80 inches.

This means that a Cal King is not only longer but more oriented towards tall people and those who prefer a lot of space for stretching or sleeping without bending their knees of legs.

But the difference when compared to a standard King is not that much. So, if you don’t fit in a King mattress by more than 4-inches, then you will have to look for another mattress size.

The best of all, Cal King mattresses may also come with a split-sizing feature. This allows splitting the width in two if you want much space on the sides. But, you will still enjoy its lengthiness.

On the other hand, you have the King size. It is excellent for couples; thanks to its 76-inches width. It works well enough to keep sleepers away from each other, while also offering enough space for combination sleepers to enjoy their sleep.

However, they can be too wide for many rooms, so it is essential to always have a wide enough room before buying.

Similarly to Cal King mattresses, these can also come with split-size designs. This helps to reduce the width or length of the mattress whenever needed. Whether it is to separate two sleepers or simply to use the mattress and save some space.

The surface area of the California King mattress usually is 6,048 Square inches. A standard king offers 6,080 inches instead. You could easily say that California is the perfect king size for taller people, while the standard King is for those who need the space.

Cal King vs King – Performance


The performance between a Cal King vs. King is hard to describe. Not only because these sizes of the mattress can be built in many different ways, but because the difference is not really that much whether it comes to width or length.

Yet, there’s still a slight change between the two that is worth mentioning.

This difference comes mainly on the amount of space available in the Cal King for the feet, and the King on the sides.

Users who are tall would easily say that they can have a better sleeping experience with a Cal King than with a King. It gives excellent feet space, and sometimes even helps to sleep more comfortably by preventing leg bending.

A King size mattress, on the other hand, offers lots of space on the sides. While it is isn’t necessarily short, its length is not that much.

Short users can benefit a lot from this size, especially if they are combination sleepers who move a lot at nights, or couples who want to feel more space on their sides.

Another essential difference is motion isolation. While the Cal King is lengthier, it does not offer much motion isolation for its less wide build. In contrast, a King mattress offers a wider build which keeps movement to each side. But of course, this is also about materials and build, more than just size.

What Does Each Mattress Weigh?


When comparing a California King vs King regarding weight, there’s not much to say. Either of the mattresses can be heavier or lighter, it all depends on the overall construction, materials used, and so on.

Overall, however, California Kings mattresses tend to be lighter.

Their build frequently uses lighter materials and promotes a softer experience than in King mattresses. But of course, it all depends.

Most of the time you would find them at similar weights, and that’s precisely because their dimensions are not too different really.

Will the Mattresses Stand the Test of Time?


King mattresses are more popular than Cal King. You may be wondering why, but no, it is not a matter of durability. They are more popular than the other because of the size available and the number of products for King available out there.

Similarly to Queen mattresses, King ones come in a wide array of designs and overall constructions, while Cal King options are not that many.

This makes it easier to say that King mattresses can be more durable than Cal King options. Yet, it all depends on many other things apart from simply their size differences.

What Sleep Position is Each Mattress Best For?


The sleeping positions differ in King vs California King mattresses. This is surprising because the differences in size are not really too noticeable at first, yet the experience will tell the whole change in comfort when using them.

It is common to find sleepers looking for at least 2-feet of space in each side of the mattress, from top to bottom, and each side as well. This makes it easier to sleep and more comfortable with time.

As you know, Cal King mattresses are longer than Kings, which are in fact wider than the former. So, you get different builds for different positions.

People who prefer Cal King mattresses tend to be tall people who sleep in back or stomach positions. While standard King mattresses are preferred by those who are more active at night, combination and side sleepers.

Which Mattress is the Firmest?


As we said before, the construction of each of these mattresses size can differ exponentially.

However, Cal King mattresses tend to use lighter products which are eventually softer than those used in regular King ones.

But it’s a matter of overall build and design so it wouldn’t be accurate to say this is a rule, but more of a common difference.

Which has The Highest Ratings?


As you know already, California King size mattresses are not as popular as regular King ones. This means they are not as accepted or recommended by most people, and their marketing is not the same either.

However, their overall popularity grows with time, and they’re gaining some field.

But only when you consider the accessories available for each one, you can see how performs far better for customers than the other. Here, we can easily say that a King mattress has better ratings than a Cal King one, and will do for a long time.

King vs Cal King – Which One Should I Buy?


When it comes to King vs. Cal King sizes in mattresses, we always go for the most convenient one. In this case, we can’t say which is the most convenient, but we can say that California King mattresses have a much better future in the market than King ones.

We can say this because people who tend to use King-size mattresses usually complain about their length.

Instead, the Cal King offers enough length for even the tallest users out there. Also, it tends to be lighter, and provide a slight improvement in transportation ease.

But of course, it is not the mattress for everyone. If you prefer sleeping close to another person and you don’t have a problem with movement, this one is for you.

Otherwise, a King mattress can be a great choice too. It all comes down to what you prefer.
