What Are The Dimensions Of a California King Mattress? Size, Fit, and FAQs
If you’re searching for “What Are The Dimensions Of a California King Mattress”, you’re usually trying to figure out whether this extra-long mattress will fit your room, your bed frame, and your height. This guide explains the exact measurements, how a California king compares to other mattress sizes, and what to consider before choosing one.
What Are The Dimensions Of a California King Mattress?
A standard California king mattress typically measures:
- 72 inches wide x 84 inches long
(about 6 feet wide x 7 feet long)
This makes it narrower but longer than a standard king mattress.
While these are the commonly accepted dimensions, minor variations can occur between manufacturers, often by an inch or less. The overall shape and purpose remain the same: a long, spacious bed that offers extra length.
How Does a California King Compare to a Standard King?
Many people mix up king and California king. The key difference is proportion—width vs. length.
| Mattress Size | Width (inches) | Length (inches) | Best For |
|---|---|---|---|
| Queen | 60" | 80" | Singles or couples in average rooms |
| King (Standard) | 76" | 80" | Couples wanting maximum width |
| California King | 72" | 84" | Taller sleepers or narrow rooms |
So, while a standard king is wider, a California king is longer. If your priority is extra legroom, the California king may be more suitable.
Why Does the Length of a California King Mattress Matter?
The extra length of a California king mattress can be especially helpful if:
- You are tall and find your feet hanging off shorter beds.
- You prefer extra space at the foot of the bed for pillows, pets, or stretching out.
- Your bedroom is longer than it is wide, and a narrower, longer bed fits the layout better.
In many bedrooms, that additional 4 inches of length can help the bed align better with windows, doors, or walkways while still providing a generous sleeping area.
Will a California King Mattress Fit in My Bedroom?
When asking “What Are The Dimensions Of a California King Mattress”, most people also want to know: Will it overwhelm my room?
Here are a few general points to consider:
- Room size: Many sleepers find that rooms at least 12 feet x 12 feet are more comfortable for a California king, but this can vary with your furniture layout.
- Walking space: Aim to leave clear walkways (ideally around 2–3 feet) around the sides and foot of the bed where possible.
- Other furniture: Dressers, nightstands, and benches all take up additional space, so it helps to measure these along with the mattress.
📝 Tip: Use painter’s tape or cardboard on the floor to outline 72" x 84". This makes it easy to see how a California king will sit in your actual space.
Do I Need Special Bedding and a Different Bed Frame?
Because the dimensions of a California king mattress differ from a regular king, it usually requires:
- California king–specific bed frame or base
Standard king frames are often too wide and not long enough. - California king sheets and bedding
Fitted sheets, mattress protectors, and some comforters are cut to match the 72" x 84" surface.
Using the wrong size bedding can lead to poor fit, with sheets that pop off or bunch up, so it helps to check that products are labeled specifically for California king.
Is a California King Mattress Right for Me?
A California king mattress might be worth considering if:
- You are taller than average and need more foot room.
- You share the bed but do not need the maximum width of a standard king.
- Your room layout favors a narrower, longer bed.
- You like the idea of a spacious sleeping area with extra length for stretching out.
On the other hand, if your priority is maximum sharing space side-to-side, a standard king may feel roomier.
