It can be confusing shopping for a mattress. Do you need a queen size mattress or will a full size do? Maybe a king size would be better, but what about a California king size? Is a twin size the same as a double? It can be really frustrating trying to figure out the proper mattress dimension. However, the best way to shop for the proper mattress dimension is to know what you are doing and what you are looking for before stepping foot into the store.

A twin size mattress is often called a double as well. The average mattress dimension of a twin size is 39 x 76 inches. While you can also find twin extra long mattresses that measure 39 x 80 inches. A full size mattress is a bit bigger and it measures 54 x 75 inches. A queen is the most popular size of mattress and it is 60 x 80 inches. If you are looking for a very large mattress a good choice is the king size which is 78 x 80 inches. A California king is a little different, and it measures 72 x 84 inches.

The best way to be sure that you are getting the proper sized mattress for your bed frame is to double check the measurements of your bed frame and then double check the mattress dimension of the new mattress before you leave the store. Typically when you are purchasing bedding, you will be fine if you purchase bedding that is labeled the same as your mattress.
