What is a Wyoming King bed?

The Wyoming King is the smallest of the square oversized beds: 84 × 84 in (213 × 213 cm), or 7 × 7 ft. It takes the length of a California King (84 in) and makes the bed just as wide, which gives it 49 sq ft of surface against 42.2 for a standard King.

Unlike some oversized sizes, the Wyoming King is listed at the same 84 × 84 in by all four specialist makers we checked.

Wyoming King vs. King, California King and Alaskan King

  • vs. King (76 × 80 in): 8 in wider and 4 in longer.
  • vs. California King (72 × 84 in): same length, 12 in wider.
  • vs. Alberta King (96 × 96 in): 12 in smaller each way.
  • vs. Alaskan King (108 × 108 in): 24 in smaller each way; the Alaskan King has 81 sq ft against 49.

Every oversized size side by side, with feet, centimeters and room sizes: biggest bed sizes compared.

Who is a Wyoming King for?

An 84 in width gives two adults 42 in each, more than the 38 in each on a King, or three sleepers 28 in each (our calculation). It suits a couple who shares the bed with one young child or a large dog, and tall sleepers who like a California King's length but find it narrow. For two adults and two children, look at an Alberta King or an Alaskan King instead. The same arithmetic for the bigger square is in Alaskan King bed size: 54 in each for two adults.

Will a Wyoming King fit in your bedroom?

With 30 in of walking space on both sides and at the foot, a Wyoming King needs a room of at least 12 × 9.5 ft (3.7 × 2.9 m), by our calculation. That is 2 ft less in each direction than an Alaskan King needs, which makes the Wyoming King the easiest oversized square bed to fit in an ordinary master bedroom.

Getting it in is easier too. One maker says it rolls its 84 × 84 in mattresses into a smaller box that fits through a standard doorway.

Wyoming King sheets and bedding

King and California King sheets are too narrow for an 84 in wide mattress. Look for sheets sold for the Wyoming King size, with a pocket deeper than your mattress is thick.

Wyoming King or Alaskan King?

  • Choose the Wyoming King if your room is under about 14 ft on the headboard wall, if the extra space is for one child or one dog, or if budget matters.
  • Choose the Alaskan King if four people will regularly sleep in the bed, or if you want the full 9 ft length.
  • In between: the Alberta King (96 × 96 in, also sold as Vermont King) splits the difference.
  • Tall sleepers: compare with the Texas King (80 × 98 in), made for length rather than width.
