What is a Wyoming, California, and Alaskan King Size bed?
For many sleepers, a standard king-size bed simply isn’t enough. When comfort expectations exceed traditional dimensions, extra-large beds provide a noticeable upgrade. Among them, the California King is the most widely known, while Wyoming King and Alaskan King beds remain more specialized but offer even greater sleeping space.
Wyoming King Size Bed
Measuring 84 x 84 inches, the Wyoming King mattress is perfectly square. This balanced shape provides generous width and length without becoming overwhelming, making it an excellent option for couples who want more space without committing to the sheer size of an Alaskan King. If your mattress measures 84×84 inches, you’re looking at a Wyoming King bed.
California King Size Bed
The California King measures 72 x 84 inches. Despite its name, it is not the largest king-size bed. Instead, it trades width for length, making it a popular choice for taller sleepers who need extra legroom but don’t require additional width.
Alaskan King Size Bed
With massive dimensions of 108 x 108 inches, the Alaskan King is the largest bed size available on the market. It offers an expansive sleeping surface ideal for co-sleeping families, multiple pets, or anyone who wants the maximum amount of space possible.
Comparison of Wyoming King bed vs California King bed vs Alaskan King bed
The primary difference between these beds lies in how their dimensions serve different needs. The Wyoming King, with its square 84 x 84-inch footprint, strikes a balance between width and length, making it practical for large bedrooms without dominating the entire space.
The California King is the narrowest but longest option at 72 x 84 inches, which makes it especially suitable for tall individuals who prioritize legroom over shared width.
At the extreme end, the Alaskan King bed spans 108 x 108 inches. Its massive size offers unmatched comfort and freedom of movement, but it also requires significant floor space and careful room planning.
