California King vs King (Mattress Size Differences)

These options cater to different sleepers and accommodate various room sizes. Twins, Twin XLs, Fulls, Queens, Kings, and California Kings exist. Other, more custom options can be purchased (like an Alaskan King), but these are the common ones that can be found in stores. Each of these mattress sizes comes with its own associated cost and available products such as bed frames, sheets, and box springs.

Standard King-sized mattresses are sometimes known as Eastern Kings, while California King mattresses are known as Western Kings. Here, we will refer to them as only California and Standard King. California King Mattresses are commonly assumed to be larger than the standard king, but they are a little smaller and are easier to place into smaller areas. However, their height can be an advantage for taller individuals who need more room for their head and feet.

Differences Between a King and a California King

California King Mattress: A California King sized mattress is the second largest mattress on the market, only falling below the king by 32 square inches of surface area. The highlight of the California King is that the mattress has a longer length, allowing extra foot room for those individuals over the 6 foot range.

California Kings are a little more specially made though, so may not be available in the stores, and accessories for the mattress (like bed frames, or sheets) may be more difficult to find.

King Mattress: A king sized mattress is a mattress that is the equivalent of two Twin XL mattresses put together. The 80 inches of length gives room for individuals up to about 6 feet tall. Its width also provides ample space on both sides, making it a perfect option for couples.

The width of the king-sized mattress is the largest standard size mattress available, as well as the largest surface area. This gives rooms for couples to spread out and have more room to sleep. This also leaves a little bit of room if a child or animal likes to climb into bed as well.

Being the largest mattress available it is important to make sure there is space in the room for the mattress to go, as well as room to get it into the space.

Mattress Size

King Dimensions: A king-sized mattress takes the width of a queen mattress and adds a large 16 inches to it, making room for an additional person for sure. As for the length it sticks with the standard if the Twin XL mattresses and the queen mattresses. This brings the overall mattress size to 76 inches wide by 80 inches deep.

California king dimensions: The dimensions of a California King is just a little different than the regular king-size mattress. The California King sized mattress actually has a 4 inch difference that it takes from the width of the king mattress and puts it on the length to add extra room for taller folks. This brings the California King sized mattress to a size of 72 inches wide by 84 inches long.

According to Nectar Sleep, taller individuals may discover that standard mattress sizes do not provide sufficient length, making the California king bed an ideal option. This larger mattress is well-suited for rooms that are longer but narrower in shape. However, it’s important to ensure there is adequate extra space on the sides of the room to accommodate the increased dimensions of a California king bed.

Mattress Surface Areas

The biggest difference between the king-sized mattress and the California king is 32 square inches or surface area. While this doesn’t seem like much, it can change how much space is needed in the room for the bed to fit properly, and how many people can fit comfortably.

King surface area = 76 X 80 = 6080 sq. in. This surface area is a little larger and offers more width for couple to spread out or add others to the bed.

California king surface area = 72 X 84 = 6048 sq. in. This surface area is a little smaller than the standard king size (which surprises many) but offers more room for longer people to straighten out while sleeping.

Room Size

Both mattress sizes can provide comfort depending on individual preference and room dimensions. The cost and availability of materials and related products will also influence your choice between these two options.

When it comes to King-sized mattresses and California king-sized mattresses, the biggest struggle is going to be making sure they fit into the desired space.

This not only saves room for someone to get in and out of the bed from either side but also leaves room for nightstands or other items placed at the end of the bed. California and king-sized beds are meant more for master bedrooms than guest rooms, apartments, or shared rooms.

The choice of fabric and material used for the bedding can greatly impact the overall feel of the room and how well it accommodates different body types, such as side sleepers.

In rooms with less space, it is better to choose the California King sized mattress as it is a little smaller and can easier fit into a room that is a little snug.- interior designer Savannah Phillips.
