If you’re shopping for a new bed, you might be asking, what’s the size of a California King mattress? It’s a common question, especially for taller individuals or those with spacious master bedrooms. This guide will give you all the details you need, from exact dimensions to shopping tips.
Let’s get straight to the numbers. A standard California King mattress measures 72 inches wide by 84 inches long. That’s 6 feet across and a full 7 feet in length. It’s famous for being the longest standard mattress size available in the US.
Many people confuse it with the regular Eastern King. The Eastern King is wider but shorter. It measures 76 inches wide by 80 inches long. So, the California King is better for length, while the Eastern King offers more width.
What’s The Size Of A California King Mattress
As stated, the core dimensions are 72″ W x 84″ L. But it’s important to think about the entire footprint, including the bed frame. Most frames add 2 to 5 inches per side. So, your bed’s total space requirement can be closer to 74-82 inches wide and 86-89 inches long.
Always measure your room before buying. You’ll want at least 2 feet of walking space on three sides of the bed. This makes it easy to get in and out and to make the bed.
California King vs. Other Standard Sizes
Seeing the size compared to others helps a lot. Here’s a quick breakdown of common US mattress sizes:
- Twin: 38″ x 75″ – Best for children or single adults in tight spaces.
- Twin XL: 38″ x 80″ – Common in college dorms; offers extra length.
- Full (Double): 54″ x 75″ – Fits one adult comfortably or two cozily.
- Queen: 60″ x 80″ – The most popular size for couples; a good balance.
- King (Eastern King): 76″ x 80″ – Offers the most width for couples (16″ more than a Queen).
- California King: 72″ x 84″ – Offers the most length (4″ more than a King).
The California King sacrifices a bit of width compared to the standard King. But it gains significant length. This trade-off is perfect for specific needs.
Who is a California King Mattress Best For?
This size isn’t for everyone, but it’s a game-changer for the right person. Consider a California King if:
- You or your partner are over 6’2″ tall. The extra foot of length compared to a Queen is a lifesaver.
- You have a narrow but long bedroom layout. The shape can fit certain rooms better.
- You sleep with pets or children who like to stretch out at the foot of the bed.
- You prefer more personal sleeping space lengthwise rather than widthwise.
If you and your partner both like to spred out sideways, a standard King might be the better choice. It gives you each 38 inches of width, compared to 36 inches on a Cal King.
Shopping for California King Bedding and Frames
One thing to note is that bedding can be slightly harder to find and sometimes more expensive. Not all stores carry full selections in this size. Here’s what you need to know:
Sheets and Comforters
You must buy sheets specifically labeled “California King.” Standard King sheets will not fit. The fitted sheet will be too wide and not long enough. Look for deep-pocket sheets if your mattress is over 12 inches thick.
Bed Frames and Foundations
You need a frame or adjustable base designed for a California King. An Eastern King frame will be too wide and not long enough. Many modern frames are adjustable, so you can lock them into the correct dimensions. Always double-check the product specifications before ordering.
Headboards and Footboards
Similarly, your headboard must be compatible with a 72-inch wide bed. Some headboards are adjustable, while others are fixed. The same goes for footboards, if you choose to have one. This is a common oversight during the shopping process.
How to Measure Your Room for a California King
Don’t just guess. Follow these steps to ensure it fits perfectly:
- Clear the Space: Move furniture away from where the bed will go.
- Measure the Area: Use a tape measure to find the exact length and width of the floor space you’ve allocated.
- Account for the Frame: Add at least 5 inches to both the mattress width and length for the frame.
- Check Walkways: Mark the proposed bed perimeter with tape on the floor. Ensure you have at least 24 inches for walkways.
- Consider Doors and Closets: Make sure doors, closet doors, and drawers can open fully with the bed in place.
Don’t forget to measure your stairwells and hallways too. Getting a large mattress upstairs can be a challenge. You need to ensure it can physically reach the room.
The Pros and Cons of a California King
Let’s weigh the advantages and disadvantages honestly.
Pros:
- Superior length for tall sleepers.
- Feels spacious and luxurious in the right room.
- Less common, so it feels like a custom choice.
- Great for stretching out without feet hanging off.
Cons:
- Bedding is less available and can cost more.
- Room must be long enough, not just wide enough.
- Offers less width per person than a standard King.
- Can be difficult to move and maneuver in tight homes.
Cost and Investment Considerations
A California King mattress often comes at a premium price. Because it’s a specialty size, manufacturers produce fewer of them. The cost for the mattress, frame, and bedding will typically be higher than for a Queen or even a standard King.
Budget for the entire ecosystem, not just the mattress. A high-quality California King sheet set is a necessary investment. It’s also wise to check return policies, as moving a mattress this size for a return can be complicated.
Care and Maintenance Tips
Caring for a large mattress has it’s own tricks. Here are some key tips:
- Use a mattress protector from day one. Replacing such a large mattress is a big expense.
- Rotate the mattress head-to-foot every 3-6 months to ensure even wear. Some models only need rotating, not flipping.
- Vacuum the mattress surface reguarly to remove dust and allergens.
- Check the center of the mattress for support. Larger mattresses can sag in the middle if the foundation is weak.
Ensure your foundation or bed slats are no more than 3 inches apart. This provides proper support and prevents damage to the mattress materials.
Making the Final Decision
Choosing a mattress size is a long-term decision. Before you commit to a California King, ask yourself these final questions:
- Have I measured my room and accounted for all furniture?
- Is the primary need extra length, or would extra width be better?
- Am I prepared for the slightly higher cost and lower availability of bedding?
- Does everyone who will sleep in the bed agree on the size?
If the answers point toward the unique dimensions of a California King, you can shop with confidence. You’ll enjoy one of the most spacious sleeps available.
