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”
