Choosing between a California King and Alaskan King mattress can feel overwhelming. You’re standing in your bedroom, tape measure in hand, wondering which oversized mattress will transform your sleep experience. Both options promise luxury and space, but they serve different needs entirely.
This comprehensive mattress size comparison cuts through confusion. We’ll explore dimensions, benefits, drawbacks, and help you decide which king-size mattress deserves a spot in your master bedroom. Whether you’re a tall sleeper, a growing family, or someone who values room to sprawl, this guide has answers.
What is a California King Mattress?
The California King mattress measures 72 X 84 inches, making it America’s longest standard mattress option. This extra-long mattress originated in Los Angeles during the 1960s, designed specifically for taller individuals and narrow bedroom layouts.
At 6,048 square inches of sleeping surface, the Cal King bed offers four inches more length than a standard king mattress (76 X 80 inches). However, it’s four inches narrower too. This trade-off creates an ideal solution for tall sleepers who don’t need excessive width.
The Cal King remains popular in Western states, particularly California. Mattress availability has improved dramatically over the years. You’ll find this size at most major retailers, both online and in physical stores. The dimensions make it a comfortable sleeping solution for couples who prioritize legroom over sprawling horizontally.
Pros of California King Mattress
Extra Length
The 84 inches in length provides exceptional comfort for anyone over 6’2″. Your feet won’t dangle off the edge anymore. This extra legroom eliminates the cramped feeling many tall individuals experience with standard beds. Compared to the 80-inch length of traditional king beds, those additional four inches make a substantial difference in sleep quality.
Easily Fits in Most Master Bedrooms
Room space constraints often determine mattress choices. The Cal King’s narrower 72 inches in width allows it to fit comfortably in bedrooms measuring 12 X 12 feet or larger. This mattress for master bedroom won’t overwhelm your space like wider alternatives might.
Bedroom furniture arrangement becomes simpler too. You’ll have adequate walking space around the bed. Dressers, nightstands, and other essentials fit without creating a cluttered environment. This dimension works particularly well in longer, narrower bedroom layouts common in older homes.
Ample Space for Couples
Beds for couples need sufficient personal space. Each person gets approximately 36 inches of width on a California King. While this seems narrow compared to standard kings, the extra length compensates beautifully. Partners who are tall or prefer sleeping diagonally will appreciate this configuration.
Movement isolation improves when you’re not fighting for foot space. Your partner’s restless legs won’t kick you throughout the night. Co-sleeping mattress arrangements with pets or occasionally with children become more manageable with that extended length.
Reasonably Priced
Affordable luxury mattress options abound in California King sizes. Prices typically range from $800 to $3,000+, depending on materials and brand quality. This pricing sits comfortably between queen and specialty oversized mattresses.
The standard king latex mattress often costs similarly to Cal King versions. You’re not paying premium prices for what’s essentially a standard configuration. Long-term value remains excellent since these mattresses typically last 7-10 years with proper care.
Easily Available
Finding a California King latex mattress or any material type is straightforward nowadays. Major brands like Turmerry, Saatva, and Purple manufacture this size regularly. Online shopping has expanded options even further.
Bedding availability has improved tremendously too. Sheets, comforters, and mattress protectors specifically designed for 72 x 84 inches dimensions are readily accessible. While selection might not match queen sizes, you won’t struggle finding quality bedding anymore.
Cons of California King Bed Mattress
Narrow Width
The 72 inches in width creates limitations for broader-shouldered sleepers. Couples who enjoy spreading out horizontally might feel cramped. This narrow width bed doesn’t suit everyone’s sleep preferences, particularly those who toss and turn frequently.
Standard king mattresses provide 76 inches of width those four extra inches matter more than you’d think. Side sleepers who curl up need more horizontal space. Beds for heavy sleepers might feel restrictive if both partners are plus-size individuals.
Bedding Challenges
Despite improved availability, bedding challenges persist with California Kings. Sheet sets cost approximately 15-30% more than standard king options. Design variety remains limited compared to more common sizes.
Custom bedding sometimes becomes necessary for specific thread counts or luxury materials. This non-standard mattress size requires careful shopping. Always verify dimensions before purchasing some manufacturers label standard kings as “king” without clarifying the distinction.

What is an Alaskan King Mattress?
The Alaskan King mattress represents America’s largest commercially available bed at 108 X 108 inches. This square-shaped bed provides an astounding 11,664 square inches of sleeping surface nearly double a California King’s area.
Often called the “true giant” of mattresses, this oversized mattress isn’t found in regular stores. Custom manufacturers typically produce Alaskan Kings to order. The massive dimensions create a sleeping experience unlike anything else available domestically.
This extra-large bed mattress suits families who co-sleep regularly, exceptionally tall or heavy individuals, or those who simply want unprecedented size. The 9 X 9 feet footprint requires careful planning before purchase.
Pros of Alaskan King Mattress
Unprecedented Size
At 108 X 108 inches, this mattress dwarfs all standard options. The mattress surface area equals approximately 81 square feet of sleeping space. That’s enough room for two adults, multiple children, and pets simultaneously.
Comparing it to the California King mattress dimensions (42 square feet), the Alaskan King nearly doubles available space. This wide mattress eliminates any feeling of confinement whatsoever.
Luxurious Comfort
Sleeping on an Alaskan King feels like having your own personal resort. The psychological benefits of ample sleeping space cannot be overstated. You’ll never accidentally elbow your partner again. Each person can sprawl comfortably without compromise.
The premium mattress price reflects this hotel-suite level luxury. But for those who prioritize sleep quality above all else, the investment pays dividends in rest and relationship harmony.
Ideal for Co-Sleeping
Family beds reach their pinnacle with Alaskan Kings. Parents with young children who bed-share find this size absolutely perfect. Everyone gets adequate personal space while maintaining closeness.
Pets can join without forcing anyone to the edge. This co-sleeping mattress accommodates multiple dogs or cats comfortably. The size reduces the risk of children rolling onto the floor during sleep.
Great for Entertainment
Your bedroom becomes a multi-functional sanctuary. Reading, gaming, working on laptops, or watching movies becomes significantly more comfortable. Breakfast in bed actually makes sense with this much real estate.
The spacious bedroom beds transform your private space into an entertainment hub. Couples can engage in separate activities simultaneously without feeling cramped.
Extra Space for Heavier and Taller Individuals
Beds for tall individuals don’t get better than this. At 108 inches in every direction, even someone 7 feet tall sleeps comfortably diagonally. Heavier sleepers appreciate the distributed weight support across a massive surface.
Plus-size couples find adequate personal space approximately 54 inches per person when sleeping side-by-side. This configuration eliminates the cramped feeling common with smaller mattresses.
Cons of Alaskan King Mattress
Space Constraints
Room size for mattress becomes critical here. You need bedrooms measuring at least 16 feet x 16 feet realistically. Anything smaller creates a furniture-dominated space with inadequate walking room.
Moving this oversized mattress through doorways and up stairs often proves impossible. Some owners resort to hoisting mattresses through windows. Delivery logistics require careful planning and sometimes professional movers.
Price Tag
The price of oversized mattresses starts around $2,000 and easily exceeds $8,000. Custom manufacturing drives costs up significantly. Frame construction, specialty foundations, and custom bedding add thousands more.
Premium mattress options like organic latex or memory foam in Alaskan King sizes command premium prices. Total ownership costs including all accessories typically range from $5,000 to $15,000+.

What to Consider Before Choosing Between a California King and an Alaskan King Bed?
Room Size
Measure your room before falling in love with either option. California Kings need 12 X 12 feet minimum. Alaskan Kings demand 16 X 16 feet realistically. Don’t forget walking space around the bed.
Bedroom furniture fit matters too. Will your dressers, nightstands, and chairs still fit comfortably? Sketch a floor plan including all furniture before committing. Doorway widths and ceiling heights affect delivery feasibility as well.
Budget
Crunch the numbers honestly. California Kings offer cost-effective luxury at $800-$3,000. Alaskan Kings start at $2,000 and climb rapidly. Include frames ($500-$2,000), foundations ($300-$800), and bedding ($200-$600) in calculations.
Long-term value differs too. California Kings have better resale potential. Alaskan Kings become difficult to sell or transport during moves. Factor in these considerations when evaluating total investment.
Sleeping Arrangements
Who shares your bed regularly? Couples might prefer California King’s reasonable dimensions. Families co-sleeping with children benefit from Alaskan King’s room to sprawl. Consider your household’s current and future sleeping needs.
Pets sharing the bed tip scales toward larger options. Multiple dogs or cats occupy surprising space. Think about your sleep preferences and whether you value length or width more.
Bedding and Accessories
Research bedding for non-standard mattress sizes before purchasing. California King sheets cost 15-30% more than standard options but remain accessible. Alaskan King bedding requires custom orders frequently, adding 50-100% to costs.
Choosing bedding and accessories becomes an ongoing expense. Mattress protectors, fitted sheets, and comforters need replacement every few years. Availability and cost should influence your decision significantly.
Personal Preference
Your sleeping style matters most ultimately. Do you sleep diagonally? Toss and turn frequently? Prefer spreading out or staying compact? Comfortable sleep solutions depend on honest self-assessment.
Test mattresses in stores when possible. While you can’t try Alaskan Kings easily, experiencing California Kings helps. Consider whether you’re choosing based on needs or wants both valid but different motivations.
Conclusion
The California King vs Alaskan King mattress debate ultimately depends on your unique circumstances. California Kings offer practical luxury for tall sleepers with reasonably sized bedrooms and moderate budgets. The 72 x 84 inches dimensions provide excellent length while maintaining accessibility.
Alaskan Kings represent ultimate sleeping luxury. The 108 x 108 inches create unmatched space for families, co-sleepers, and those who refuse compromise. However, they demand substantial financial investment and massive bedroom space.
Room measurement for mattress selection can’t be overstated. Measure carefully, consider your budget realistically, and think about long-term needs. Both options deliver quality sleep when properly matched to circumstances.
