Other than personal taste, there are a number of factors to think about before selecting your mattress size. Have you considered: the dimensions of the bedroom, if you plan to share the bed with your partner or pets, the importance of open space versus sleep space to you? There are size descriptions below and a Cal King Mattress size guide that will give you a better idea of how to choose a mattress online.

Cal King

84"
72"

The California King mattress measures an astounding 72 inches wide and 84 inches long (183 x 213 cm) and is the longest mattress size out there. It’s perfect for taller individuals thanks to its exceptional length, especially those taller than six feet. Clearly you don’t have to be a tall person to enjoy the roominess of a California King, as you will find plenty of space to enjoy with your partner, children, and/or pets.
