The Wyoming King measures 84×84 inches (213×213 cm), making it a square-shaped bed that sits between the standard US King and the massive Alaskan King. It's often considered the 'sweet spot' for families who want significantly more space than a King but don't have the room for an Alaskan King. The Wyoming King is identical in dimensions to the UK Emperor bed, though the two evolved independently in their respective markets.

The Wyoming King is ideal for:

  • Couples who want more room than a standard King
  • Parents co-sleeping with one child
  • Anyone who finds a standard King just slightly too small
  • Those who prefer a square sleeping surface

Minimum Room Size

The square shape of the Wyoming King requires a room that is at least 13 feet wide and 13 feet long to allow comfortable movement around the bed.

Advantages of a Wyoming King Bed

  • Perfect square sleeping area
  • Noticeable upgrade from a standard King
  • More manageable size than an Alaskan King
  • Same dimensions as many UK Emperor beds

Considerations

  • Requires a large, square bedroom
  • Specialty bedding is required and can be expensive
  • It is a fixed, standard size with no customization option

The Wyoming King occupies a unique position in the oversized bed market. It is large enough to make a real difference for co-sleeping families, yet not so massive that it completely dominates the room or requires an unusually large bedroom. Its dimensions of 213×213 cm make it identical to many Emperor beds sold in the UK, though the two names evolved independently in their respective markets. This square footprint is a key feature, offering a balanced and generous sleeping surface that many prefer over a rectangular bed. It represents a practical step up in the world of oversized beds.
