What to Consider When Choosing a King or California King Mattress
Dimensions
These are the two largest sizes among the standard mattress sizes. However, they have variations in their dimensions that could make one better for you than the other.
To start, there’s the stand King size, which measures 76 inches wide by 80 inches long. Kings are more well-known and might be the first choice people think of when they want to upgrade from a Queen.
A California King, on the other hand, is 72 inches wide and 84 inches long. California Kings aren’t as popular, but they have an important factor: they’re 4 inches longer than a King. On the flip side, the King is slightly shorter, but it’s also wider than the Cali-King.
Price
Even though the costs of the mattresses themselves are usually similar, the additional costs of maintaining both types can be different. For instance, California-size King beds are less popular and may be harder to come by.
As such, this could make purchasing spare parts such as bed frames, box springs, and bedding more challenging or costly. So, if you are looking for affordability and convenience, you may prefer the standard King size.
Comfort
Of course, comfort is key when shopping for any mattress size. Usually, California or regular King beds are purchased by couples since the extra surface space is not as necessary for most solo sleepers. The benefit of these mattress sizes is that they’re both more roomy. However, deciding between the two may come down to your body types and how much space you want to spread out.
California Kings are longer, so if you or your partner is very tall, then this is probably going to be better choice. Conversely, if you both value the most space possible for spreading out, then the wider King size would be ideal.
Bedding
It’s important to note that because California Kings are slightly longer and regular Kings are wider, you won’t be able to use the sheets on these bed sizes interchangeably. This means that if you do buy a California King, you’ll need to be able to find California King-size sheets. Luckily, many companies carry this size, but it is slightly harder to find in all styles than standard King bedding. In some cases, it may be a bit more expensive, though the difference in cost is usually negligible.
Since a top comforter doesn’t need to fit the bed as precisely, you could probably get away with using a King on a California King, and vice versa, just for practicality’s sake. However, if you want the bed to look as nice as it can, we’d recommend buying the comforter that goes with your bed size.
Room Size
As we mentioned, California Kings measure 72 inches wide by 84 inches long, and standard Kings measure 76 wide and 80 inches long. This makes the California King a longer and slightly narrower bed, and the King, a wider and slightly shorter bed.
Keep these shapes and dimensions in mind when thinking about the room you’re going to put the bed in. If the space for the bed is wider than it is tall, it might be a better space for a standard King, but if you have more room to spare length-wise than width-wise, it may be a better spot for a California King.
If you have an extremely large room, it likely won’t matter as much. Just be sure you have at least 2 feet on the sides and foot of the bed to walk around it comfortably. Be sure you’re measuring the room’s dimensions carefully – especially the spot where you want to put the bed – before deciding between a California or standard King.

FAQs About King vs. California King Mattresses
Which is better, a California King or a King bed?
Deciding which bed is better for you will really depend on your height and sleeping situation. California Kings are longer and narrower, while standard Kings are shorter but wider. This makes California Kings a good choice for those who are exeptioanlly tall and who don’t mind sleeping a little more snugly with a bed partner. Standard Kings provide a little bit more space for couples sharing the bed and are likely the better choice for those who aren’t extremely tall.
Can I put a California King on a King frame?
Since the California King is 4 inches longer and 4 inches narrower than a standard King mattress, you’ll need to specifically buy a California King bed frame to support it. This is also true going the other way – a King-sized mattress won’t fit correctly on a California King bed frame.
What is the advantage of a California King mattress?
The California King is designed for taller people who don’t feel comfortable on a standard, 80-inch-long mattress. It includes 4 extra inches in length, so those who are 6 feet and over should be able to stretch out and sleep comfortably without their feet dangling off of the bed.
This bed type is also slightly narrower than a regular King-size mattress, which may be a plus depending on the dimensions of the room you’re putting it in.
Is a California King-size bed wider or longer?
The California King-size bed is longer than the standard King-size bed, not wider. In fact, it is 4 inches narrower than the regular King-sized bed. This makes it a good option for those who are tall and who don’t mind sleeping a bit closer to their significant other.
Conclusion
As you can see, there is a slight yet defining difference when it comes to choosing between a California King and a standard King-size bed. King beds offer more width, while Californa Kings offer more length.
So with that in mind, it’ll come down to the preferences and needs of you and your partner. Are you taller? Do you like more space to spread out? Answering these questions and other considerations with your room space can help narrow down your decision.
