Wyoming King vs. Alaskan King vs. Texas King: What's the Difference?

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 9 inches in width compared to a King mattress; and 12 inches width compared to a California King mattress.

  • Great for couples who sleep with a child and/or a pet

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.
