A standard queen-size mattress is 60 inches wide and 80 inches long. It is ideal for two adults.

A queen-size mattress provides 30-inch elbow space for a single person. It does not leave much space to share the bed with kids or pets.

  • Spacious
  • Fits into all standard bedrooms


  • Cannot fit more than two people

Things to Consider Before Deciding Between California King Size vs Queen Size Mattress

Room Size

A California king-size mattress is a great option for large master bedrooms or long and narrow bedrooms that are 12 by 12 feet (up to 13 by 19 feet). 

Queen-size mattresses are ideal for small master bedrooms or guest rooms. A room that is 10 feet by 10 feet should allow the space you need to set up the bed and add some furniture as well. Anything smaller will feel cramped for you and your partner


A California king-size mattress can range anywhere between  $1,000 to $2,000 for a hybrid mattress. It is the largest mattress size and is the more expensive option between queen vs Cal king.  

A queen mattress can cost anywhere between $750 and $1000 depending on the brand and quality. Often you could get a package deal that would include other bed accessories such as mattress protectors, bed sheets, duvets, etc., at a discounted price.  

Bed Size

For a California king-size mattress, a bed smaller 72 by 84 inches will have edges hanging from the sides. A standard Cal king bed will measure the same as a mattress. A smaller bed will damage the mattress in the long run and also make it uncomfortable to sleep on. 

The ideal bed size for a queen size mattress would be 60 inches by 80 inches. A queen-size bed comes with the same measurement and can comfortably accommodate a queen-sized mattress within the frame. 


An important factor that affects your choice between California king vs queen is your height. The extra length at the base of the California king-size bed is perfect for people taller than 6 feet.  

For people shorter than 6 feet, a queen-size mattress works well. Tall people may have the risk of having their feet hanging from the bed while sleeping.  


California king-size mattresses certainly offer the luxury of space compared to their queen-size counterpart. You can have two pillows, a few cushions, and also a duvet. While a queen size can accommodate two pillows and a few cushions. 

Between Cal king vs queen, accessories for a queen size mattress will be more accessible and cheaper than a Cal king mattress.
