You’ll notice that in comparison, standard kings have more of a square shape, while California kings look more rectangular.

Wyoming King Bed Size

The Wyoming King bed measures 84″ × 84″. The Wyoming King Mattress is a step larger than the California King. It has 84 inch of length like a California but adds an additional 8 inches to the width. The larger size allows users to spread out and get comfortable. It is great for instances where more than two people share the bed. Whether someone shares a bed with a large pet or a child with needs, theres always ample room with a Wyoming King. The Wyoming King Mattress is not available from most retailers so finding one isn’t always easy!

The Pros and Cons of a Alaskan King Mattress Size


  • The long length is great for those who are taller.
  • The extra width of the Wyoming King fits more than two people.
  • The large surface area of a Wyoming King mattress is great for larger individuals.


  • The Wyoming King requires a lot of space, so it requires a larger room.
  • Sheets may be difficult to find for this size and you may find you have limited colour and thread count choices.

Is A Full Bed Big Enough For Two

The full-sized bed can fit two people. In fact, full mattresses were the most common size used by couples in the 1960s. They are advantageous because they are able to fit into smaller rooms. However, many adults these days prefer a larger bed. The full bed is 53 inches by 75 inches, leaving only 26.5 inches across for each personâs personal sleeping area. The slightly larger queen bed offers 30 inches of space per person, while a king offers 38 inches per person. Depending on you and your bed mateâs sizes and sleeping styles, you may consider a queen or a king rather than a full.

Alaskan King Size Mattress

An Alaskan king mattress is the biggest bed size sold. At 108 inches wide by 108 inches long, its large enough to comfortably sleep three adults or a co-sleeping family with two or three small children. Its also a good option for couples who both starfish sleep or have entirely different sleep schedules so they wont disrupt each other when getting in and out of bed.

The Alaskan king has a surface area of 11664 square inches, almost double the standard king size mattress. Its 32 inches wider and 28 inches longer than your standard king bed as well.

Since Alaskan kings are both large and not readily available, they can get quite expensive, costing between $2500 to over $5000. Your bedroom should be at least 16 by 16 feet to fit an Alaskan king bed in it.

Olympic Queen Mattress Dimensions

What is the largest mattress size?

66 inches by 80 inches

Minimum recommended room size: 10 feet by 10 feet

The Olympic queen mattress is six inches wider than the standard queen size and provides enough room for a couple to sleep comfortably, but is not considered to be a standard size. Even when found, its an ordeal to find bedding accessories like sheets to match this size.

The benefit of an Olympic queen size is that it provides a little extra space than the queen size, while not being as big as a king. If your room is not big enough to accommodate a king, but you need more space for sleepers, then this Olympic queen size fits the bill. The Olympic queen size is meant for RVs and camper trailers and are more commonly seen inside mobile homes.

Minimum recommended room size: 9 feet 6 inches by 10 feet 6 inches

The full XL size has an extra 5 inches in length than a standard full. The extra legroom makes it a good fit for taller individuals sleeping by themselves.

Usually, the California king size bed takes the prize as the largest bed size. It has a length of 84 inches and a width of 72 inches. However, some people consider the Eastern king bed, which is another name for the standard king bed, as the largest.

However, there are companies in the mattress making industry that go-ahead to make mattresses that are way bigger and larger than most standard beds. The emperor size bed, for example, is 215 cm long and 215 cm wide.

This is much larger compared to other standard sizes of mattresses. This mattress also comes in different lengths. As spacious as they are, however, they are rare, and may thus not be easily found.

Caesar mattress sizes are the largest possible mattress size available. They are even larger than emperor size beds with a dimension of 245 cm in width and 220 cm in length.

Things To Consider Before Purchasing A Mattress


Whether you’re interested inmemory foam or latex foam, it’s a good idea to consider a bed’s pros and cons before making a selection, like size, price, and accessory affordability.


There are a couple of sizing aspects when it comes to selecting the right mattress. First, consider your current sleeping habits. Do you:

If so, then you know that it’s time to upgrade from your current mattress size to the next one up.

However, its not just the size of your mattress that will determine how much space you’ll have in bed. Your beds size also depends on how much space you have in your room.

When shopping for a bed, consider your room size and how much space you’ll have to move around. A good rule of thumb is to leave about two feet of space on either side of the mattress.


If you’re on a bed that makes you groan with aches and pains every morning, then you know it’s probably time to upgrade to something more comfortable.
