California King Dimensions: A Comprehensive Guide

Is your bed too short for your towering stature? Too narrow to share with a partner and a pet? Enter the California King - a mattress size that reigns supreme in terms of length.

If you’ve heard the term but are unsure of the specifics, this guide will break down everything you need to know about California King dimensions.

What Is a California King?

While you might think that a California King is simply a royal resident of the Golden State, in the world of sleep, it refers to a mattress that is longer and somewhat narrower than the standard King bed. Perfect for taller individuals and those who need extra length, a California King is designed to offer a regal sleep experience.

California King Bed Size: The Specifics

The precise dimensions of a California King bed are:

  • Width: 72 inches
  • Length: 84 inches

Why Choose a California King?

  • Extra Length: Provides more room for taller people.
  • Width Comfort: Offers enough space for a couple.
  • Pet-Friendly: Can comfortably accommodate a small pet at the feet.

If you’re particularly interested in a California King, Puffy Mattresses offer a range of options with excellent pressure relief and cooling features.

How Big Is a California King?

If you’re struggling to visualize the exact size, consider that a California King is big enough to comfortably fit two adults and a small pet. While its width is four inches narrower than a standard King bed, it gains those four inches in length.

How It Compares to Other Sizes

To give you a clearer understanding, here’s a quick comparison with other popular mattress sizes:

Mattress Size Width (inches) Length (inches)
Twin 38 75
Queen 60 80
King 76 80
California King 72 84

How Wide Is a California King Bed?

At 72 inches wide, a California King bed offers ample space for couples. It’s a luxurious size that allows for personal space while sharing the bed, perfect for couples who like their room while sleeping.

How Long Is a California King Bed?

A California King bed is 84 inches long, which makes it the longest standard mattress size available. If you’re taller than 6 feet, you’ll appreciate the extra length.

If length is a primary concern for you, consider the Puffy Lux Mattress in California Kins size. With its 84-inch length, it offers ample legroom and a premium sleep experience.

How Do I Know If I Have a King or a California King?

Given the small but significant differences in dimensions, it’s essential to know what you’re sleeping on, especially when buying bedding accessories. Here’s how you can distinguish:

  • Check the Tag: It should indicate the dimensions or type.

Other Key Considerations

Who Should Consider a California King?

  • Taller Individuals: Clearly, the added length is beneficial for those over 6 feet tall.
  • Couples: If both of you are above-average in height, this is an ideal choice.
  • Room Dimensions: If your room is more rectangular than square, a California King may fit better.

How to Choose the Right Bed Frame for a California King

  • Check for Sturdiness: Given the size, you need a frame that can support the weight.
  • Room Space: Ensure there is at least 2 feet of space on all three sides of the bed for easy movement.


The California King is more than just a luxurious mattress size; it’s a necessity for taller individuals and those who require extra length in bed.
