Alaskan King vs. King vs. California King Mattress

Perhaps you’re wondering how big an Alaskan King is compared to a standard large mattress size – or, perhaps you’ve never even heard of the term “Alaskan King” before now. Either way, you’re probably about to learn something new about this obscurest of mattress sizes.

What Is an Alaskan King Mattress?

An Alaskan King is a size of mattress that measures nine feet wide by nine feet long.

Alaskan King (Obscure) vs. California King and King (Standard)

In comparison to a California King, an Alaskan King is bigger. (A California King is 84” long by 72” wide; a King is 80" long by 76" wide; an Alaskan King is 9’ long by 9’ wide.)

Why Choose One Over the Other?

Both Alaskan King and California King and King mattress sizes have their pros and cons.

Alaskan King Pros & Cons:

  • Pro: For couples, the extra big dimensions mean more personal space for each person.
  • Pro: The novelty aspect. Owning a mattress this big is pretty rare – and the excitement may never wear off!
  • Con: It’s bulky. An extra big mattress size requires a lot of space, which most of us don’t have to spare.
  • Con: It’s costly. An extra big mattress requires more materials and labor to make, resulting in a bigger price tag.
  • Con: It’s heavy. In other words, it’s hard to move.

California King and King Benefits:

  • Pro: It’s more affordable, since it doesn’t require as much manual labor or materials to produce.
  • Pro: It’s more accessible. (CKs and Kings are considered standard, and so are virtually sold wherever mattresses are sold.)
  • Pro: It’s more space-saving. A smaller mattress is the more economical choice, space-wise.
  • Con: Not as big as an Alaskan King. (But still, pretty big!)
