Alaskan King vs. California King: Which One Is Better for You?

Choosing between an Alaskan King and a California King can feel confusing at first. Both are larger than standard beds, both offer extra room, and both can make your bedroom feel more luxurious.

But they are built for very different sleepers.

A California King gives taller individuals a little more legroom without taking over the entire bedroom. An Alaskan King, on the other hand, offers a truly oversized sleep surface with enough space for couples, kids, pets, and anyone who wants room to stretch out in every direction.

In this guide, we’ll compare Alaskan King vs. California King beds by size, bedroom fit, comfort, sleeping space, and who each mattress is best for.

Alaskan King vs. California King: Size Comparison

The first thing you need to compare when looking for a bed or mattress is the size. The Original Alaskan King is one of the biggest oversized mattresses, and it features an incredible 11,664 square inches of sleeping surface. That’s enough sleeping space for the whole family.

In comparison, the California King has a sleep surface of “only” 6,048 square inches. Here is how they compare in size.

  • California King: 72" Width x 84" Length
  • Alaskan King: 108" Width x 108" Length

The Alaskan King is square-shaped, compared to the rectangular shape of the California King. The Alaskan King is also 24” longer and 36” wider than the California King, which is a considerable size difference.

Alaskan King vs. California King: Bedroom Size Recommendation

Another thing you need to consider when buying a new bed is the size of your bedroom. The average bedroom size in the US is 11 x 12 feet, while master bedrooms are somewhat larger, standing at 14 x 16 feet.

The recommended room size for the Alaskan King is 16x16 feet, so you’ll need a master bedroom that’s bigger than the standard one. In comparison, the recommended room size for a California King bed is 10x12 feet. That means that it can fit into your regular bedrooms, guest rooms, and master bedrooms.

How Each Bed Feels When You Sleep

The biggest difference between an Alaskan King and a California King isn’t just the measurements. It’s how the bed actually feels when you’re sleeping, stretching, rolling over, or sharing the space with someone else.

A California King is longer than a standard King, which makes it a good option for taller sleepers who need a few extra inches of legroom. However, it is also narrower than a standard King, so couples may notice less side-to-side space, especially if one person likes to sprawl or both sleepers move around at night.

An Alaskan King gives you more room in every direction. At 108” x 108”, it offers enough length for tall sleepers and enough width for couples, children, and pets to share the bed comfortably. Instead of sleeping close to the edge or adjusting every time someone moves, everyone gets more space to settle in.

That extra surface area can make a big difference for families who co-sleep, couples with different schedules, active sleepers, and pet owners. There’s more room to stretch out, change positions, cuddle, or create a little breathing room when you need it.

Who Should Buy the Alaskan King?

The Alaskan King bed is perfect for families that like sleeping together. It can comfortably fit two adults, two to three small children, as well as any furry friends. This bed provides enough space for everybody to stay comfortable during the night so that nobody gets disturbed when switching positions or going to the bathroom at night.

A big sleeping surface is perfect for couples with different sleeping schedules, as enough room provides an option of not waking up your partner when getting in or out of bed. It is also perfect for couples who simply want a larger sleeping surface so that they can spread out during the night.

The Alaskan King can be a good option for people over seven feet. They know how hard it is to find a bed where your feet won’t hang off the edge, and this one can be a perfect choice.

Lastly, the Alaskan King is great for people with pets, as this oversize mattress provides enough space for your furry friends to cuddle up together and sleep restfully.

Who Should Buy the California King?

With a length of 84”, the California King is an excellent option for taller individuals who need an extra few inches. It’s suitable for solo sleepers who prefer extra space and couples who don’t mind sleeping close together, as the California King is a little narrower than a standard King-sized bed.

Lastly, people with long and narrow rooms can have some trouble fitting in the square-shaped bed, which is why a rectangle-shaped one like the California King can be the perfect solution.

Which One to Choose?

Choosing between the Alaskan and California King depends purely on your sleeping preferences, available space, and budget. You should get the Alaskan King if you need an oversized bed where your whole family can co-sleep. On the other hand, the California King may be a better option for singles or couples with a smaller bedroom.

The California King is a more affordable option, and you can find it in almost any mattress store, while the Alaskan King is more expensive and harder to find. Luckily, our online store has a selection of luxurious hand-crafted Alaskan King mattresses that can be an excellent addition to your bedroom. 

Frequently Asked Questions

Do you need a special bed frame for an Alaskan King?

Yes. An Alaskan King mattress needs a frame or foundation designed to support its oversized dimensions. A standard King or California King frame will not fit properly and may not provide the support your mattress needs.

Is an Alaskan King harder to move than a California King?

An Alaskan King takes more planning to move because of its size. Before buying, check your doorways, hallways, staircases, and bedroom layout. Many oversized mattresses are designed with delivery and setup in mind, but it’s still worth confirming the details before ordering.

Can you use regular pillows on an Alaskan King bed?

Yes, you can use regular pillows, but you may want more of them to fill out the larger sleep surface. Many people pair standard or King pillows with oversized comforters, larger blankets, and decorative pillows to make the bed feel balanced.

Is an Alaskan King worth it if you don’t co-sleep?

Yes. While Alaskan King beds are popular with families, they’re also great for tall sleepers, active sleepers, pet owners, and couples who simply want more room. If you value space, comfort, and a more luxurious sleep setup, it can still be worth the investment.
