What Is a Wyoming King Bed?

Dimensions: 84-by-84 inches

Named after a state known for its wide open spaces, the Wyoming king mattress dimensions span a whopping 7-by-7 feet, making it 8 inches wider and 4 inches longer than a standard king bed. It boasts a large surface area of 49 square feet and is the entry-level oversized mattress size. 

While this mattress size isn’t as popular as others, such as the California or Alaskan king, the Wyoming king bed frame offers a range of unique benefits and plenty of room to accommodate small families and tall sleepers. 

Who Is the Wyoming King Size Best For?

The Wyoming king size bed is best for couples who co-sleep with a child or multiple pets or those who prefer to sprawl out at night. It offers over half a foot more width than a standard king for plenty of added space. But because the Wyoming king is the smallest of the oversized mattresses, it’s typically not suited for co-sleeping with multiple children. 

A Wyoming king mattress is best for:

• Parents who co-sleep with one child
• Tall or large sleepers 
• Couples who sleep with multiple pets
• Couples who prefer the starfish sleeping position
• People who want the luxury feel of an oversized mattress

Benefits of a Wyoming King Bed

So what exactly are the benefits of this larger mattress size? The Wyoming king bed is unique because of its perfectly square configuration. It offers plenty of sleeping room for multi-pet families and co-sleeping parents. Here are the top benefits of choosing a Wyoming king bed:

• Great for co-sleeping arrangements: The Wyoming king bed offers 8 extra inches of width and 4 extra inches of length compared to a standard king, making it great for parents who co-sleep with one child (or multiple fur babies at the foot of the bed). 
• Space for any type of couples sleeping position: If you and your partner like to sprawl out at night, a Wyoming king bed gives you ample room to move around and take up space. 
• Extra legroom for tall people: A Wyoming king bed accommodates people up to 7 feet tall whereas a standard king only accommodates those up to 6 feet 6 inches tall.
• Perfectly square to fit your room: Unlike a standard rectangular king mattress, the Wyoming king is perfectly square for easier room configuration. 

Wyoming King Mattress Size Comparison

Wyoming king beds are bigger than standard, California, and super king sizes (also known as Eastern king beds), but when it comes to oversized mattresses, it’s the smallest. Texas, Alberta, and Alaskan king beds are all larger than a Wyoming king mattress. 

From smallest to largest, here’s a helpful mattress dimension comparison chart:

Wyoming King vs. California King

California king: 72-by-84 inches

The California king mattress is one of the most popular non-standard king sizes, but how does it compare to the Wyoming king? When it comes to California king sizes, the California king mattress is the same length – 84 inches – but not as wide at just 72 inches. When you want more width than what the California king offers, the Wyoming king size is the next best choice. 

With the same length as the California king but a foot more width, the Wyoming king size is a better choice for couples who co-sleep with a child or those who want to fill a large room with a bigger bed. 

Wyoming King vs. King

King: 76-by-80 inches

When comparing standard king vs. Wyoming king dimensions, the Wyoming king is much larger. The Wyoming king mattress is 4 inches longer and 8 inches wider than a standard king size bed, making it bigger in every way than a king. The Wyoming king offers a surface area of 49 square feet compared to a standard king at just over 42 square feet. 

If you need more width and length than a king bed offers, the Wyoming king size might be right for you. 

You might be wondering how this compares to a split king mattress. A split king measures the same as a king bed at 76-by-80 inches. The only difference is that a split king consists of two twin XL mattresses in a single king size bed frame.

Wyoming King vs. Texas King

Texas king: 80-by-98 inches

The Texas king mattress is second largest to the Wyoming king, hence why it’s named after the second largest state. Measuring 98 inches long and 80 inches wide, it’s 14 inches longer than the Wyoming king, but the Texas king is not as wide as the Wyoming king. 

If you have multiple pets that sleep at the foot of the bed, a Texas king mattress might be a better fit than the Wyoming king size, although it won’t be as suited for co-sleeping with children due to its shorter width. 

Wyoming King vs. Alberta King

Alberta king: 96-by-96 inches

Similar to the Wyoming king mattress, the Alberta king is square instead of the traditional rectangular bed shape. The Alberta king mattress measures 8 feet wide and 8 feet long, making it a foot longer and wider than the Wyoming king. 

Since the Alberta king is one of the largest bed sizes available, it’s best suited for large families. With a surface area of 64 square feet, you can comfortably sleep two adults, two children, and two pets.   

Wyoming King vs. Alaskan King

Alaskan king: 108-by-108 inches

The Alaskan king bed is the largest oversized mattress available, apart from some family size beds. Like the Wyoming and Alberta sizes, the Alaskan king mattress is square, measuring 9-by-9 feet. It’s 2 feet longer and wider than the Wyoming king.

Given the dramatic size of the Alaskan king bed, it’s best suited for extra-large rooms. If you need significantly more square footage than the Wyoming king offers, an Alaskan king mattress might be for you, with a surface area of 81 square feet.

What To Consider Before Buying a Wyoming King Size Bed

Buying a bed is a big investment, and you want to make sure you choose the right mattress. When deciding if a Wyoming king size bed is right for you, you’ll want to consider key factors like how big your room is and the budget you have available. 

Room Size

Your room should be no smaller than 11-by-11 feet if you’re thinking of buying a Wyoming king mattress. This will leave you with 2 feet on either side of the bed. 

A Wyoming king bed will fit the best in a 14-by-14 foot room, as it will feel more spacious. Since the Wyoming king bed is square, you’ll also want to consider how the configuration will look with any other furniture in the room.

Number of Sleepers

How many people (and pets) sleep in your bed will affect the mattress size needed. If you’re planning on using a Wyoming king mattress to co-sleep, two adults and one child can fit comfortably. If you’re looking to fit more people or multiple large animals, you may need to upgrade to an Alberta or Alaskan king mattress. 

Body Size

Larger mattresses support more weight, which is important depending on how many people will be sleeping in the bed and their body size. Mattress weight limits vary depending on the type of bed and materials used, so you’ll want to check the product details before purchasing a Wyoming king mattress to make sure it will work for your needs.  

Comfort Preferences

When it comes to finding the right mattress, comfort is everything. You’ll want to consider ideal mattress firmness and support depending on your sleep needs. Most people opt for a medium-firm mattress, but you may want to consider one on the firmer side to extend the longevity of your mattress given the higher price point of a Wyoming king. 

The type of mattress you opt for will also affect your comfort. Different materials, such as memory foam or hybrid, will offer unique cooling, motion isolation, and pressure relief benefits. Knowing your preferences will help you make the right choice on whether a Wyoming mattress is right for you. 

Personal Space

If you’re looking for an oversized mattress, chances are you prefer more personal space when sleeping. This is especially true if you struggle with sleep disturbances or have a different sleep schedule than your partner. A Wyoming king mattress provides ample room for couples to spread out.

If you’re purchasing a mattress to co-sleep but still want plenty of personal space, you should carefully consider the right bed size for your needs. At 7-by-7 feet, you should be able to fit two adults and one child comfortably — and potentially a small pet. 

Availability

Like any oversized mattress, the Wyoming king mattress size isn’t available everywhere. This bed size is less common and very few retailers carry them. You may need to custom order a Wyoming king bed or go through a specialty retailer. Because of the lack of availability, you’ll also likely have fewer options for materials and accessories — like Wyoming king bed frames, pillows, and sheets. 

Budget

How much you spend on a mattress is usually correlated with size. A Wyoming king mattress will cost more than a standard king size mattress given its larger size and lack of availability. While the average hybrid mattress starts at $1,200, a Wyoming king mattress can cost anywhere from $2,000 to $6,000 or more depending on the type of mattress, such as a cheaper spring bed vs. a more luxurious foam mattress like Purple’s RejuvenatePremier™ Mattress.

Sleep Better With Purple

The Wyoming king bed is oversized to fit a range of needs. It offers space for a family of three and provides ample room for pets and those who prefer more personal space. But most couples don’t need (or have room for) such a large bed. 

In fact, standard king and California king mattresses are some of the best large bed sizes for couples. Whether you opt for a Wyoming king bed or something slightly smaller should be based on your unique needs and preferences — no two couples are the same. 

While Purple doesn’t offer Wyoming king size beds, we do offer a range of large mattresses in standard king, split king, and California king sizes that offer support and pressure relief for restful sleep.
