This article will provide an in-depth analysis of the California King and Alaskan King beds, highlighting their similarities and differences and which might best fit your needs.

Understanding the California King Bed

The California King bed, or Cal King, is a favorite for those who prefer extra length and a slightly narrower width. With dimensions of 84 inches in length and 72 inches in width, it offers an additional 4 inches in length than a standard King bed. This is ideal for taller individuals who want to avoid their feet hanging over the mattress edge.

Pros of a California King Bed

  • Widely available: California King mattresses can be easily found at mattress dealerships, along with standard Queen and King beds, making them a convenient choice for shoppers.
  • Suitable for smaller bedrooms: The smaller size of the California King bed makes it easier to fit into bedrooms with limited space, accommodating couples without overwhelming the room.

Cons of a California King Bed

  • Limited space for larger families: While the California King bed can comfortably accommodate couples, it may not provide enough space for larger families who prefer co-sleeping.
  • Restricted width: The narrower width of the California King bed may not suit individuals who prefer more space to spread out while sleeping.

Exploring the Alaskan King Bed

The Alaskan King bed is the largest oversized mattress for those seeking the ultimate sleeping space. With dimensions of 108 inches in length and 108 inches in width, the Alaskan King bed provides ample space for couples, children, and even pets. It is a great option for individuals with large bedrooms and the desire to create a luxurious sleeping environment.

When making a decision between a California King and an Alaskan King bed, there are several factors to consider. Let’s explore the main distinctions between these two mattress sizes.

Room Size

One of the most crucial considerations when choosing between a California King and an Alaskan King bed is the size of your bedroom. The California King bed, being a standard size, can fit into an average-sized room while still allowing for sufficient movement. On the other hand, the Alaskan King bed requires a clutter-free and spacious bedroom, with walls measuring 15-20 feet each. Attempting to fit an Alaskan King bed into a smaller room may result in a cramped and uncomfortable space.


Another important factor to consider is the cost of these larger mattresses. California King beds are generally more affordable compared to Alaskan King beds. The price of a California King mattress can range from $700 to $4,000 on average, while an Alaskan King mattress typically costs between $2,000 and $7,000. It’s essential to factor in the cost of accessories and delivery fees when budgeting for an oversized mattress.

Sleeping Partner

The number of individuals who will be sharing the bed is a crucial consideration. A California King bed offers ample space for two people and even a child or pet. It is particularly suitable for couples who have different sleeping habits and preferences. On the other hand, an Alaskan King bed is the ideal choice for families with more than two children or individuals who want to share the bed with their partner, children, and pets.

Height and Weight

The height and weight of the individuals using the bed should also be taken into account. California King beds are suitable for taller individuals requiring extra length to accommodate their height comfortably. They also work well for plus-sized sleepers who desire more space to spread out and enhance their sleep experience. Alaskan King beds, being even larger, are a great option for both tall and plus-sized individuals, providing ample room and support.

Ideal Sleeping Position

The preferred sleeping position and personal space preferences also play a role in choosing the right mattress. A California King bed is recommended for couples who enjoy sleeping closer together. The additional space reduces the chance of disturbance caused by one partner’s movement. On the other hand, an Alaskan King bed is favored by couples who prefer more personal space while still sharing a bed.

Where to Buy Oversized Mattresses

Finding oversized mattresses such as the Alaskan King, Wyoming King, and Texas King can be a challenge at traditional mattress stores. However, with thorough online research, it is possible to identify companies that specialize in creating these unique sizes. Some boutique bedding companies are willing to create custom oversized mattresses using different materials such as latex, memory foam, innerspring, or hybrid designs.
