Quick answer: A Wyoming King bed measures 84 inches wide by 84 inches long (7 ft × 7 ft, about 213 × 213 cm). That is 8 inches wider and 4 inches longer than a standard King. Its square shape gives couples, families and tall sleepers more room in every direction without the huge footprint of an Alaskan King. Plan for a bedroom of at least 12 × 12 ft. Because Wyoming King frames are rarely stocked, most are built to order.
Key takeaways
- A Wyoming King is a 7-foot square: 84" × 84", giving 49 square feet of sleeping surface.
- It is 8" wider and 4" longer than a King, and 12" wider than a California King at the same 84" length.
- It suits rooms of 12 × 12 ft or larger. That is the smallest room that comfortably fits an oversized king.
- Wyoming King sheets and mattresses are specialty items. The bed frame is the hardest part to find.
- Candace & Basil builds Wyoming King bed frames in-house from solid maple, in any of our bed designs.
Wyoming King bed dimensions
A Wyoming King mattress is 84" W × 84" L. Some makers vary by about an inch, so a custom frame should be built to your actual mattress. The outside footprint of an upholstered Wyoming King frame is usually a few inches larger than 84" on each side, and more with a deep, padded headboard.

| Alberta King | 96" × 96" | 64.0 sq ft | Alberta is 12" bigger each way |
| Alaskan King | 108" × 108" | 81.0 sq ft | Alaskan is 24" bigger each way |
Wyoming King vs. California King: which should you choose?
Both are 84 inches long, so they are equally good for tall sleepers up to about 6'2". The difference is width. A California King is 72" wide, which is actually 4 inches narrower than a standard King. A Wyoming King is 84" wide. That extra foot of width matters to couples, parents with a child who climbs in at night, and anyone sharing the bed with a dog. If your room can take it, a Wyoming King gives you California King length without giving up width.
Wyoming King vs. Alaskan King
Both are square, but the Alaskan King (108" × 108") is 2 feet bigger in each direction and needs a room of at least 14 × 14 ft. A Wyoming King suits rooms of about 12 × 12 ft. It is the better choice when you want an oversized bed without the bed taking over the whole room. See our oversized king beds comparison for every option.
Who is a Wyoming King bed for?
- Couples who want real personal space. Each person gets 42" of width, which is wider than a Twin XL (38") each.
- Families who co-sleep with one small child, or with pets.
- Tall sleepers who want California King length with extra width.
- Square or nearly square bedrooms, where a square bed looks better than a long, narrow one.
What size room do you need for a Wyoming King?
- Minimum: 12 × 12 ft. That leaves about 30" of walkway on each side and at the foot.
- Comfortable: 13 × 14 ft or larger, if you want nightstands, a dresser and doors that open freely.
- Measure from the wall, not the mattress, because the headboard adds depth.
Wyoming King bed frame: what to look for
- Solid hardwood rails and a center support rail, so an 84" span does not sag.
- A platform or slat base sized exactly to 84" × 84". A King base leaves an 8" gap.
- Construction that comes apart, so the frame fits through doorways and up stairs.
- The right headboard height. A square bed looks best with a headboard in proportion; we offer 42", 52", 62" or 72".
Where to find Wyoming King sheets and mattresses
No standard sheet size fits 84" × 84". Wyoming King fitted sheets are made by specialty bedding sellers or made to measure. An oversized King duvet or coverlet can often cover the top, as long as it is at least about 100" wide so it hangs over the sides. Mattresses come from custom mattress makers. See our specialty size bedding and mattress guide for the details. When you order a frame, we can connect you with suppliers.

You choose the headboard height (42", 52", 62" or 72"), the fabric and the finish, and we ship across the contiguous USA from our Miami showroom.
