What Is a California King Mattress?

A California king mattress is one of the biggest mattresses on the market. They are typically longer than traditional mattresses, using a different shape that caters to taller people and narrow bedrooms. California king mattresses have a reputation for being spacious, but is a California king the right size for you? Let’s discuss the details and dimensions of this mattress size.

California King Mattress Dimensions

California king mattresses are usually 84 inches long and 72 inches wide. Because the California king mattress dimensions differ from standard king mattresses, they create a more rectangular shape, whereas king mattresses are closer to a square.

California king mattresses can have slightly different dimensions when customized or manufactured by certain companies. But 84 x 72 inches is the standard. We offer California kings in unique sizes, like 83 x 71 inches and 83.46 x 72.05 inches. We also have California kings with varying thicknesses, ranging from 12 to 14 inches deep. You can easily find the perfect size for your sleep and space needs!

Is a California King Mattress Bigger Than a King?

Many assume a California king is larger than a king mattress. However, the California king mattress size can be slightly smaller. We’ll further explain the specific dimensions below, but the main takeaway is that standard king beds often have more surface area. So, kings are technically larger. However, some say the California king feels bigger because of its length.

King vs. California King Mattress

As mentioned, California kings are more rectangular, with the standard dimensions being 72 inches wide and 84 inches long. King mattresses have a more square shape, with an average 76-inch width and 80-inch length. This means the standard California king mattress has a surface area of 6,048 square inches, while a king has 6,080 square inches of surface area.

Choosing a California King

We recommend a California king mattress for people close to or over 6 feet tall. These beds are ideal for tall, single sleepers and folks with long, narrow bedrooms. Finding accessories for California king beds can be more challenging because they’re less common. But we have a plentiful collection of and bed foundations for all mattress sizes as well as cozy California king comforter sets!
