Ideal for whom

Before you proceed to buy a King or a California King size mattress, you must consider the below points to make sure you are making the right move.

  • Owing to the dimension, if the person sleeping is less than 6’4″ then Kingsize Mattress is ideal, but if the height is higher than this, there is no other choice than go for California King size Mattress as this extra boot space in length will not let the leg hang.
  •  If the person sleeping has Arthritis and keeps changing positions while sleeping then King size will give the support because of its wider space area without the fear of falling especially for a restless couple.
  • Even in the case of accommodation of a child along with the couple, it is very much feasible without any discomfort for a California King Size Mattress to give extra space for adjustment which is not the case in King Size Mattress.
  • The issue with the King Size Mattress is that the room size has to be wide enough, at least 13 feet by 13 feet to not only accommodate the Mattress along with the Bed but also for the provision of Wardrobe and free walking space around the room. The room size should be Square also to look aesthetically fit with the dimensions.

As stated above it is not idle for tall people and is quite heavy for free movement and if the owner shifts the apartment a lot then this relocation will be a tedious one.

Whereas the California King size Mattress exuberates the name itself by being the longest mattress around, designed for King size lifestyle along with that the couples can accommodate a small size child. As it is Large so the movement is a bit restricted comparatively, owing to the same fact it is difficult to find adorations to give a spontaneous look to the room.

  • The Room size should also go along with the length of the Mattress i.e it should be around rectangular in size to give a good look to it.



Since the California King Size Mattress is longer it is comfortable for taller people but the King Size Mattress is wider so the spreading capacity is higher and the movement of one person will not disturb the other due to motion transfer.


The Pricing for King Size Mattress & California King Size is somewhat the same, it depends on the type of Foam, Material, and upholstery used. At times California King Size is more expensive, but both are in the pricier bracket compared to the regular size beds because they are at least 20 inches wider and lengthier so more materials are used also which increases the manufacturing cost.

  1. Height of the person sleeping
  2. Sleeping movement habits
  3. Dimension of room
  4. Surface Area- King Size has a surprisingly larger surface area compared to California King Size Mattress.
  5. No of the person sleeping
