You might be wondering what the largest bed size available is.

In this comprehensive guide, we will explore the largest bed size, the Alaskan King, and compare it with other popular bed sizes.

The Alaskan King Bed: An Introduction

The Alaskan King is the largest bed size available on the market. Named after Alaska, the largest state in the US, this square-shaped mattress measures a whopping 108 x 108 inches (274 x 274 centimeters).

Its generous size makes it perfect for spacious rooms and families who co-sleep.

With a width of nine feet, it comfortably accommodates multiple sleepers, while its length of nine feet ensures tall individuals can sleep comfortably too.

The Origin of the Name

Contrary to what one might think, the Alaskan King bed is not named after its place of origin. Instead, it derives its name from its size.

Alaska, being the largest of all the 50 states in the US, serves as a fitting reference to this mattress being the largest bed size.

Capacity of an Alaskan King Bed

The capacity of an Alaskan King bed depends on the size of the individuals sleeping on it.

As it is larger than a standard king-size bed, it can comfortably sleep up to four adults or two adults and two children.

Even with such capacity, there is ample legroom for everyone, ensuring a comfortable sleep experience.

Wyoming King

The Wyoming King bed is an excellent alternative to the Alaskan King if you desire a slightly smaller size.

Measuring 84 x 84 inches, this bed is perfect for those who want a spacious mattress without overwhelming their room.

Some companies also refer to this bed as the Emperor King. However, it’s important to note that finding sheets for this size can be challenging.

Texas King

If you’re not a fan of square beds like the Alaskan King, the Texas King is a great alternative.

With dimensions of 80 x 98 inches, this bed is narrower and shorter than the Alaskan King.

However, it still provides ample space for tall individuals, making it an ideal choice for those who are 6.5 to 7 feet tall.

California King

The California King is one of the most popular bed sizes available and is known for its pop culture references.

With dimensions of 72 x 84 inches, it is larger than a standard King bed.

It is easier to find compared to the Alaskan King, Wyoming King, and Texas King, and offers a wide range of bedding options.


The King bed size, measuring 72 x 80 inches, is another popular option for those seeking a larger mattress.

Similar to the California King, it is suitable for tall individuals and families, including co-sleeping with children.

Finding sheets for this size is relatively easy, as it is considered a standard size carried by most manufacturers.

Olympic Queen

For those who don’t have enough space for an Alaskan King, the Olympic Queen is a viable alternative.

Measuring 66 x 80 inches, it provides six additional inches of width compared to a traditional Queen bed.

However, it’s important to note that the Olympic Queen is not a standard size, which can make finding perfectly fitting sheets a challenge.


Out of all the mattress sizes, the Queen bed size is the most popular. With dimensions of 60 x 80 inches, it is widely available in stores selling beds and sheets.

This size is suitable for single sleepers or those with guest rooms or small master bedrooms.

However, if you value extra space as a couple, a Queen bed may not provide the desired luxury.


The Full bed, measuring 54 x 74 inches, is an excellent transitional mattress and a budget-friendly option.

It is ideal for single sleepers, especially in spaces where a Queen bed may be too large.

Young adults moving into their first apartments or those with studio-sized flats will also benefit from this size.

Twin XL

The Twin XL bed, measuring 38 x 80 inches, is slightly longer than a standard Twin mattress.

This size is perfect for small rooms and single sleepers.

It can also serve as an additional bed to increase sleeping capacity in larger rooms or when accommodating a child in the same room as an adult.


Also known as a single bed, the Twin mattress is the best option for small rooms.

With dimensions of 38 x 74 inches, it is space-efficient but can feel cramped for one person.

However, it is more than enough for children and commonly used in bunk beds.


The Crib mattress is the smallest of all the mattresses mentioned in this guide. Measuring 28 x 52 inches, it is designed for babies and used in cribs.

It provides enough space for pillows and toys while ensuring firm support for the baby’s safety and reducing the risk of suffocation.

Additional Considerations When Choosing a Mattress

While size is an essential factor to consider when selecting a mattress, there are other important considerations to keep in mind.

Here are a few additional factors to consider:

1. Material

The material of the mattress directly impacts its overall quality, comfort, and temperature regulation.

Common materials include innerspring, latex, memory foam, and hybrid mattresses.

Each material offers unique benefits and considerations, so it’s crucial to choose one that suits your preferences and needs.

2. Firmness

Mattress firmness is subjective, as there is no standard measure. Some mattresses marketed as firm may still feel soft to some individuals.

It’s best to try out different mattresses before making a purchase to determine the level of firmness that suits your comfort preferences.

3. Online Purchases

Don’t be afraid to buy a mattress online. While you may not have the opportunity to try it out physically, many online mattress retailers offer generous return and exchange policies.

Reading reviews from other customers can also provide valuable insights into the comfort and quality of the mattress.


In conclusion, the largest bed size available is the Alaskan King. With its impressive dimensions of 108 x 108 inches, it provides ample space for multiple sleepers and is perfect for large families or those who desire a spacious sleeping area.

However, the Alaskan King can be expensive and difficult to find, and finding suitable sheets can pose a challenge.

When choosing a mattress, it’s important to consider not only the size but also other factors such as material, firmness, and the option of purchasing online.

By taking these considerations into account, you can find the perfect mattress that meets your specific needs and preferences.
