What is a California King Mattress?

The surface area for a California king and a standard king is the same, except a Cal king mattress is longer and narrower.

Queen vs Cal king Size Mattress: What Should You Consider Before Buying?

Room Size

Queen-size beds can fit in the master bedroom or any room measuring 10 feet by 10 feet. A Cal king mattress is longer and wider than a Queen size mattress so it would feel cramped in any room measuring less than 12 feet by 12 feet. It is advisable to consider Cal king for the larger bedroom in your house. This would give you enough space to navigate and avoid crowding the room with furniture. 


Generally, a queen bed is cheaper than a Cal king size mattress because of its size and accesibility in the market. You can expect anything between a hundred or two hundred dollars of price difference between a California king and a queen-sized mattress. So, if you’re on a tight budget, queen size mattresses should likely be your first choice. 


Both Cal king and a queen can be accessorized with two pillows or more, depending on your personal choice. A queen mattress is a common choice for buyers so its accessories are readily available. However, the accessories for Cal king aren’t as easily available as the queen mattress. 

Bed Size

If your mattress is 60 inches wide and 80 inches long, you should prefer a queen bed that is of similar dimensions. Cal king mattresses would fit perfectly on a bed that is 74 inches wide and 84 inches long since they are 12 inches wider and 4 inches longer than a queen.

The size and dimensions may vary from brand to brand. Consider the same before you purchase the mattress. 


Tall sleepers or couples over 6 feet often choose California king due to 4 extra inches in legroom. Queen beds may feel a little cramped for tall individuals. Cal king’s extra length can also be utilized by couples who are pet parents so that their pets can sleep in the extra space at the foot of the bed. 

Queen-size mattresses are a great choice for couples who love to stretch out and need a wider area to sleep comfortably.
