California King Dimensions: What You Need to Know
Shopping for a new mattress gets tricky when California King dimensions enter the picture. Is it actually bigger than a regular King? Smaller?
Why do some bedrooms need this size while others don’t? Here’s the truth: a California King measures 72 inches wide by 84 inches long, but those numbers tell only part of the story.
The real question isn’t about inches; it’s about whether this mattress fits your body, bedroom, and lifestyle. Understanding what makes a Cal King different changes everything about choosing your next bed.
What Are California King Dimensions?
A California King mattress measures exactly 72 inches wide by 84 inches long, or 6 feet by 7 feet. This gives you 6,048 square inches of sleeping space.
Many people think a Cal King is bigger than a standard King, but that’s not true. A regular King is actually 4 inches wider at 76 inches, though it’s 4 inches shorter at 80 inches.
Both sizes have nearly the same total surface area. The Cal King trades width for extra length.
California King vs King: The Complete Comparison
Choosing between a California King and a standard King bed could mean the difference between perfectly comfortable sleep and years of restless nights. Still, most buyers focus on the wrong factors when making this crucial decision.
Size Differences Explained
Although both mattresses offer similar total space, the extra width or length changes how each one actually feels in use. The difference is subtle on paper but noticeable in the bedroom.
| ASPECT | KING MATTRESS | CALIFORNIA KING MATTRESS |
|---|---|---|
| Width | 76 inches | 72 inches |
| Length | 80 inches | 84 inches |
| Key Difference | Wider by 4 inches | Longer by 4 inches |
| Surface Area | Slightly larger overall | Slightly smaller overall |
| Visual Shape | More square | More rectangular |
| Best For | Couples needing side-to-side space | Taller sleepers need legroom |
Who Should Choose a California King?
A California King works best for tall sleepers over 6 feet who need extra legroom. It’s ideal for back and stomach sleepers who stretch out lengthwise.
The narrower width fits rectangular bedrooms well. Couples who sleep close together will appreciate the added length.
Pet owners benefit from extra foot space when pets curl up at the bed’s end.
Who Should Choose a Standard King?
A Standard King suits average height couples who want maximum width for spreading out. It’s perfect for families co-sleeping with kids or couples needing personal space.
Side sleepers who curl up don’t need extra length. The wider size fits square bedrooms better. You’ll also find sheets and bedding much easier to buy for a standard King than a Cal King.
Room Size Requirements for California King Beds
Before you fall in love with a California King, make sure your bedroom can actually fit it comfortably with room to walk around.
- Minimum room size: You need at least a 12′ × 12′ room, though 12′ × 14′ works better
- Walking space: Leave 24 to 36 inches on each side of the bed for easy movement
- Best room shape: Longer, narrower rooms work perfectly for the 84-inch length
- Delivery clearance: Measure doorways and stairways before buying; you need enough space to get it inside
- Furniture placement: Plan where dressers and nightstands will fit around the extra length
Pros and Cons of California King Beds
A California King offers unique benefits but also comes with some drawbacks you should consider before buying.
- Pros: California Kings give tall sleepers extra legroom with their 84-inch length. The sleek proportions look elegant and sophisticated. They fit narrow master bedrooms beautifully, where standard Kings feel too wide.
- Cons: The 72-inch width feels cramped for some couples compared to a standard King’s 76 inches. You’ll face limited bedding options and higher costs for sheets.
Finding frames and furniture can be harder. Delivery gets tricky due to the extra length fitting through doorways.

California King Bedding and Accessories
California King bedding requires specific dimensions that don’t work with standard King sizes, which affects both availability and cost.
- Fitted sheets: You need 72″ × 84″ fitted sheets made explicitly for Cal Kings; regular King sheets won’t fit properly.
- Comforters and duvets: Look for comforters around 104″ × 98″ and duvet covers between 108″ × 92-96″ for proper coverage.
- Box springs and frames: Cal King foundations aren’t interchangeable with standard Kings, so buy the right frame.
- Split option available: Consider a split California King for adjustable bases or easier delivery through tight spaces.
- Higher costs: Expect to pay more for Cal King bedding due to limited availability and specialty sizing.
Factors to Consider When Choosing Between King and California King
Choosing between a King and California King involves more than just size; you need to think about your body, bedroom, lifestyle, and budget.
1. Your Height and Sleeping Position
Consider your height first. If you’re over 6’2″, a California King’s extra 4 inches of length prevents your feet from hanging off.
Back and stomach sleepers stretch out more than side sleepers who curl up. Don’t forget your partner’s height too; if one person is tall, the Cal King makes sense for both.
2. Bedroom Dimensions and Layout
Measure your room carefully before deciding. Square bedrooms fit standard Kings better, while rectangular rooms suit California Kings perfectly.
Think about where your dresser and nightstands will go. The bed’s proportions should match your room’s shape for a balanced, comfortable look that doesn’t feel cramped or awkward.
3. Sleeping Partners and Family Needs
Do you and your partner sleep close together or spread out? Couples needing personal space want the standard King’s extra width.
Families co-sleeping with kids benefit from that width too. If pets sleep at your feet, Cal King’s length helps. Consider how much everyone moves around during sleep.
4. Budget and Accessibility
California King bedding costs more and offers fewer choices than standard King options. While mattress prices are similar, you’ll pay extra for sheets, comforters, and accessories over time.
Standard King bedding is everywhere: department stores, online shops, and discount retailers. Cal King items require more searching and budgeting.
5. Delivery and Moving Considerations
California King’s 84-inch length creates delivery challenges through doorways and up stairways. Measure all pathways before buying.
Consider bed-in-a-box options that compress for easier delivery. Think about future moves too; will you struggle getting this mattress into your next home? Standard Kings maneuver more easily despite their width.
Wrapping It Up
Choosing between a California King and standard King depends on your height, bedroom shape, and sleeping habits.
California King dimensions: 72 inches wide by 84 inches long; it gives tall sleepers extra legroom while fitting narrow bedrooms perfectly.
Measure your room and budget for bedding costs before you buy. Now grab your measuring tape and start shopping for your perfect mattress with confidence.
