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. 

But as a Cal king mattress is longer and wider than a Queen size mattress, it would feel cramped into any room measuring less than 12 feet by 12 feet. So, it would help if you considered Cal king for the larger bedroom in your house. That would give you enough space to navigate on the side to avoid crowding. 

Bed size

If your bed is a queens size bed which is 60 inches wide and 80 inches long, you should prefer a queen bed. Cal king mattresses are 12 inches wider and 4 inches longer than a queen, so it would fit perfectly on a bed that is 74 inches wide and 84 inches long. 

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 the 4 extra inches of legroom as queen beds may feel a little cramped for them. 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. 


Generally, a queen bed is cheaper than a Cal king size mattress because of its popularity and availability on 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.
