We all know what King and California King size mattresses are. But what about a Wyoming King mattress, an Alaskan King mattress and a Texas King mattress, did you know these existed and are even bigger than a California King mattress?
Wyoming, Alaska and Texas are some of the biggest states in the US, so it's not a coincidence that these oversized mattresses are named after these states.
These three mattresses are family beds. They are perfect for people who want extra space. Such as taller people, couples who move a lot during the night, who spread out, or who sleep with their kids, and/or pets :)
How do you know which one is right for you? One thing is for sure, you will need a spacious bedroom to fit these size mattresses.
Here's a little guide to figure out what your favorite family bed.
Wyoming King
A Wyoming King bed size is an oversized custom mattress that is pretty rare on the market. The Wyoming King size mattress is the smallest one of the three, and it fits on a Wyoming King size bed frame. It measures 84 inches long by 84 inches wide. So it is as long as the California king size mattress, but it is 12 inches wider.
In comparison, a King size mattress measures 80 inches long by 76 inches wide. And a California king size bed measures 84 inches long by 72 inches wide. So if you choose a Wyoming King mattress, you are adding 4 inches in length and 8 inches in width compared to a King mattress; and 12 inches width compared to a California King mattress.
Pros:
- Extra length for taller couples
- Extra overall space for couples
- Great for couples who sleep with a child and/or a pet
Cons:
- Small for families who have two plus kids and/or two pets
- More expensive than a standard sized bed
- Need to have a big bedroom to fit this bed

Texas King
A Texas King bed size is the second largest in terms of oversized mattress size. The Texas King size mattress is longer but narrower than the Wyoming King size mattress. It fits on a Texas King size bed frame. It measures 98 inches long by 80 inches wide.
The Texas King bed is great for taller people as it is 18 inches longer than a King size bed, and 14 inches longer than a California King bed. However, if you want to accommodate more sleepers, you will want to get a Wyoming King over a Texas King, as long as your bedroom has enough space.
Pros
- Perfect for tall couples
- Perfect for tall individuals with one child and/or pet
- Best mattress for taller couples who don't have enough space for a Wyoming bed
Cons
- It's the most narrow of all the oversized mattresses
- Not enough space to fit larger families, such as a couple with two children and/or pet

Wyoming King vs Texas King vs Alaskan King: the dimensions side by side
Here is every oversized mattress size next to the two standard ones, so you can compare the sleeping surface you are actually buying. The ideal room size is a practical minimum rather than a rule - you want walking space on at least three sides of the bed.
| Size | Dimensions (W x L) | Sleeping surface | Vs a standard King | Ideal room size |
|---|---|---|---|---|
| King | 76 x 80 in | 6,080 sq in | The baseline | 10 x 10 feet |
| California King | 72 x 84 in | 6,048 sq in | 4 in narrower, 4 in longer | 10 x 12 feet |
| Wyoming King | 84 x 84 in | 7,056 sq in | 8 in wider, 4 in longer | 12 x 12 feet |
| Texas King | 80 x 98 in | 7,840 sq in | 4 in wider, 18 in longer | 12 x 14 feet |
| Alaskan King | 108 x 108 in | 11,664 sq in | 32 in wider, 28 in longer | 14 x 16 feet |
The comparison people find most surprising is Wyoming King against Texas King. The Texas King offers more total sleeping surface, but every extra inch of it is length. If your problem is a crowded bed rather than dangling feet, the Wyoming King is the better choice; if your problem is height, the Texas King is.
Common questions about oversized mattress sizes
What are the dimensions of a Wyoming King mattress?
84 inches wide by 84 inches long - 8 inches wider and 4 inches longer than a standard King, and a perfect square.
What room size do you need for a Wyoming King bed?
Around 12 by 12 feet as a working minimum. At that size you keep roughly two feet of clearance on three sides, which is enough to walk past the bed and to make it without climbing on it.
Which is bigger, a Wyoming King or a Texas King?
The Texas King has more sleeping surface - 7,840 square inches against 7,056 - but the Wyoming King is 4 inches wider. Texas buys you length; Wyoming buys you width.
Are oversized mattresses available in memory foam?
Usually, yes, though almost always made to order rather than held in stock. Memory foam and hybrid builds are the common options because both provide even support across a surface this wide without needing a centre-support rail in the way an innerspring does. Expect a longer lead time than a standard size, and check whether the price includes delivery, since these are freight items.
Do oversized beds help couples who disturb each other?
They help for the simple reason that there is more distance between sleepers, so motion transfer is felt less. That is a benefit of the size rather than of any particular material - a wider bed does not reduce motion, it just moves your partner further away from it.
Can you buy Wyoming King sheets off the shelf?
Rarely - most retailers stop at California King, which is why oversized bed owners so often end up with ill-fitting bedding. We make them, and a Wyoming King set is one fitted sheet at 84 x 84 x 16 inches, one flat sheet at 115 x 115 inches, and two King pillowcases.
