What's the Difference Between a King and a California King?

One of the most misunderstood sizes in our industry is the difference between a King and California King. Most people think a California King is larger both in its width and length than a regular king when in fact a California King is actually 4″ narrower than a regular king (sometimes called an Eastern King).

A California King is 4″ longer than a regular king making it ideal for taller individuals (over 6′ 2-4″). You do give up 4” of side-to-side space though. Another misconception is two twin foundations (box springs) will work for a king mattress. Notice that twin foundations are 6″ shorter than king foundations.


Sizing Tolerances

There is a tolerance of ± 1” from industry size measurements based on the amount of side padding and type of construction.

Below are our industry dimensions for mattress sizes (plus or minus 1"):

  • Twin: 39” x 74”
  • Full: 54” x 74”
  • Queen: 60” x 80”
  • King: 76” x 80”
  • California King: 72” x 84”
