What’s the Difference Between Alaskan King Bed & California King? 

Accommodation

When it comes to accommodation, Alaskan King beds are fantastic. They can conveniently accommodate four adults or a couple with three to four children. Depending on how well you manage your sleep positions, some space will still be available for your pet to join you. 

But it’s safe to say that Alaskan King beds are massive, and there is plenty of room for everyone. On the other hand, California King beds can easily accommodate up to 2 adults and a child or a pet.

So, there is not much space for larger families with California King beds. But that doesn’t mean Cal King is not huge. They might not be as massive as Alsakn Kings, but California King beds ample space. 

Size

Of course, being the biggest of all sizes, Alaskan King beds are 108 inches in length and 108 inches in width. It means that there is plenty of space on both sides. There is plenty of room to spread your legs and arms when you are on an Alsakan King bed, especially if there are not many people on the bed with you. 

California King beds are 84 inches in length and 72 inches in width. So, there is a relatively smaller space compared to an Alaskan King. Still, a California King does come with a pretty good pace for couples with plenty of room to spread their legs and arms. 

Availability 

As we have just mentioned, Alaskan King Beds are massive, and there are few mattress manufacturers with this size available in their offerings. Therefore, Alaska King beds are hard to find. Again, there are only a few manufacturers who deal in these beds. 

On the other hand, California King beds are much more easily available because most mattress manufacturers have this size available. Many of them have a split version of the California King too. So there are much better options available to you in this size. 

Suitability

Alaskan King Beds are suitable for larger families. It is because they can accommodate more people compared to California King beds. But another advantage they have here is that these beds are better suited for taller people or plus-sized couples. 

California King beds are better suited for everyone out there. But they work better for smaller families, and you will still have plenty of space on hand.

Area & required room size

Being the biggest size available, Alaskan King beds cover an area of 11664 square inches. Due to the massive size, these beds are suitable in larger rooms.

On the other hand, California King beds cover an area of 6048 square inches. So, these beds will cover less space in your room if you have 16 feet by 16 feet. But they are ideally suitable for rooms 12 feet by 10 feet. 

Price

Alaskan King beds do come with a massive price tag on them. And there are a couple of reasons for that. First, they are the biggest size available in beds on the market.

And secondly, there are not many mattress manufacturers out there who have their own Alaskan King Beds. So, due to their massive size and lower availability, these beds are scarce yet very expensive (check the most expensive mattresses in the world). 

On the other hand, California King beds are available from most mattress manufacturers and are relatively smaller than Alaskan King beds. Therefore, why are they readily available and are smaller? Hence, they are lesser in price.
