California King Mattresses

What Is a California King Mattress?

A California king mattress — often called a Cal king — measures 72 inches wide by 84 inches long, making it the longest standard mattress size available. Compared to a standard king (76" × 80"), a Cal king trades 4 inches of width for 4 extra inches of length, specifically designed for taller sleepers who need more legroom. At LA Mattress Stores, we carry California king mattresses from every brand in our lineup — Tempur-Pedic, Stearns & Foster, Diamond Mattress, Helix, and more — available to test at all five of our Los Angeles showrooms.

With over 27,100 monthly searches for "California king mattress" and 5,400 for "Cal king," this size is particularly popular in California and the western United States. The California king originated in Los Angeles in the 1960s, designed for the larger bedrooms common in California homes. Today, it remains the preferred size for tall individuals, couples where one or both partners are over 6 feet, and anyone who values extra length over maximum width.

Benefits of California King Mattresses

The California king offers unique advantages for specific sleepers and bedroom configurations:

• Extra Length for Tall Sleepers: At 84 inches long, the California king provides 4 more inches of length than a standard king. For sleepers 6'2" and taller, this extra length means feet don't hang off the edge — a significant comfort improvement.
• Ample Room for Couples: At 72 inches wide, a Cal king still provides 36 inches per person — the same as two individual twin beds side by side. Plenty of room for couples to spread out comfortably.
• Better Fit for Narrow Bedrooms: The California king is 4 inches narrower than a standard king, making it a better fit for bedrooms that are long but not wide. This is common in many California home layouts, especially in master bedrooms.
• Elegant Proportions: The elongated shape of a California king creates a sleeker, more proportional look in a bedroom compared to the wider, squarer standard king. Many interior designers prefer the Cal king's proportions for bedroom aesthetics.
• Available in Every Mattress Type: California king sizes are available across all mattress types — memory foam, hybrid, innerspring, latex, pillow top, and more. You don't sacrifice any comfort features by choosing this size.
• Compatible with Split Designs: Split California king mattresses allow each partner to choose different firmness levels — perfect for couples with different sleep preferences. These also work with split adjustable bases for individualized sleep positions.

How to Choose the Right California King Mattress

Shopping for a California king mattress near me in Los Angeles? Here's what to consider:

• Cal King vs. Standard King: If either partner is 6'2" or taller, the Cal king's extra 4 inches of length makes a significant difference. If both partners are under 6', the standard king's extra width (76" vs 72") may be more beneficial. Measure your bedroom to ensure proper fit — a Cal king needs a room at least 12 × 12 feet for comfortable walking space.
• Mattress Type: All mattress types are available in Cal king. Memory foam Cal kings offer excellent motion isolation for couples. Hybrid Cal kings provide responsive support with good airflow. Innerspring Cal kings offer traditional bounce and strong edge support.
• Foundation and Frame: Make sure your bed frame accommodates Cal king dimensions (72" × 84"). Standard king frames are too wide and too short. If you're upgrading from a king, you'll need a new frame or Cal king-compatible adjustable base.
• Bedding Accessories: California king sheets, mattress protectors, and bedding are different dimensions than standard king. Ensure you purchase Cal king-specific accessories — standard king fitted sheets won't fit properly.
• Delivery Access: A Cal king mattress is large. Verify that doorways, hallways, and stairways in your home can accommodate the mattress. Bed-in-a-box Cal king options solve this with compressed delivery.

California King vs. Other Mattress Sizes

California King vs. Standard King

A standard king is 76" × 80" — wider but shorter than a Cal king (72" × 84"). Both have the same total surface area (6,080 square inches for king vs. 6,048 for Cal king). Choose standard king if width matters more (side-by-side space). Choose Cal king if length matters more (tall sleepers). In Los Angeles, both sizes are equally popular and equally available.

California King vs. Queen

A queen (60" × 80") is significantly smaller than a Cal king — 12 inches narrower and 4 inches shorter. Upgrading from a queen to a Cal king adds substantial sleeping space for couples and tall individuals. However, a Cal king requires a larger bedroom. If room size is limited, a queen is more practical. We carry every mattress in queen and Cal king sizes.

California King vs. Twin XL (Split King)

Two twin XL mattresses (each 38" × 80") placed side by side equal the width of a standard king but with individually customizable firmness levels. A split Cal king uses two narrower, longer mattresses for the same individualization in Cal king dimensions. If you and your partner want different firmness levels, consider a split Cal king configuration with an adjustable base.

California King Mattress FAQ

What are the exact dimensions of a California king?

A California king mattress measures 72 inches wide × 84 inches long (6 feet × 7 feet). This makes it 4 inches narrower and 4 inches longer than a standard king (76" × 80"). The Cal king is the longest standard mattress size available in the United States.

Can I use king sheets on a California king?

No. Standard king and California king sheets are different sizes and are not interchangeable. King fitted sheets are too wide and too short for a Cal king mattress. Always purchase bedding specifically labeled "California King" for proper fit. This applies to sheets, mattress protectors, mattress pads, and comforters.

How big does my bedroom need to be for a Cal king?

We recommend a minimum bedroom size of 12 × 12 feet for a California king mattress. This provides enough space for the bed, nightstands, and comfortable walking room around all sides. Rooms 14 × 14 feet or larger are ideal. Measure your space before purchasing to ensure a good fit.

Are California king mattresses more expensive?

California king mattresses are typically priced the same as standard king at most brands. Since they use roughly the same amount of material (similar total surface area), manufacturers generally charge the same price for either size. Accessories like Cal king sheets and frames may have a slight premium due to lower production volumes compared to standard king.
