You would be right if you guessed that the king-size bed is the largest size mattress available. Because of its size, it’s a great pick for anyone who shares their bed with a partner, kids, and pets since it affords ample space for the whole gang.
Although there are variations on the king-including California, Alaskan, Wyoming, and Texas king sizes-the two most common are the standard king and the split king.
Is a king or split king mattress the right mattress size for you? Our split king vs. king guide will help you determine just that.
What is a split king?
A split king is the same size as a king, but instead of one single mattress, it’s actually two separate mattresses together on one frame.
Split king dimensions
A split king mattress measures 76 inches wide by 80 inches long, the same dimensions as a king-size bed. The difference: A split king consists of two side-by-side twin XL mattresses, each measuring 38 inches wide by 80 inches in length.
Why would you want your king-size bed to be split down the middle? There are a few good reasons. Here are the top three benefits of a split king mattress:
A split king mattress isn’t without its drawbacks. Before buying one, keep this in mind:

Difference between split king and king
A split king mattress isn’t bigger than a king-in fact, they have the same dimensions. They do have a few key differences, however. We’ve put together this handy comparison chart to help make your choice between the two easier.
Foundations for a split king
Both standard king-size mattresses and split kings can generally be paired with several foundation types, from a traditional box spring foundation to an rget=_blank href=https://www.saatva.com/bases/lineal-adjustable-base>adjustable base to a platform bed.
How do they work?
Split king foundations are split down the middle for ease of delivery. This is to ensure the foundation can be moved around tight doorways, staircases, and narrow corners. The two sections of the foundation are pushed together to make one unit.
A split foundation is standard on all king-size variations, whether a standard king, California king, or split king. A single-unit king foundation would simply be too large and difficult to maneuver.
One difference in foundations between kings and split kings is adjustability. If you pair a split king mattress with an adjustable base, you can raise and lower your head and feet separately on each side of the bed since the mattress is comprised of two separate surfaces. With a standard king, you can only raise and lower your head and feet together.
One issue with separate mattresses is that they can occasionally shift on the foundation. To keep that from happening, the easiest thing you can do is place a non-slip mattress pad between your mattress and the foundation to keep the two twin XLs from sliding around.
Is a split king the same as a king?
A split king and a king mattress have the same dimensions: 76 inches wide by 80 inches long. However, a split king mattress is split down the middle, while a standard king provides a single sleep surface.
What’s the point of a split king?
A split king mattress is a king-size mattress that’s been split down the middle. A split king allows couples to customize their sleep surface so each partner can choose their preferred mattress firmness.
What’s the advantage of a split king mattress?
A split king mattress has quite a few benefits. For starters, it allows bed partners to choose two different firmnesses so each of you ends up with the one you want.
With a split king, you also won’t feel your partner moving while you sleep since you’ll be on two separate mattresses. Finally, a split king mattress is easier to move than a standard king.
Can you cuddle on a split king?
It can be difficult to cuddle on a split king mattress because you and your partner will be separated by the division in the middle of the bed. But cuddling isn’t impossible.
So long as you’re not using an adjustable base to raise your head and feet separately, consider getting a king-size mattress topper to cover the division between mattresses or encasing your mattress in king-size sheets so you feel like you’re on one sleep surface.
