Queen size mattress dimensions

In the United States, a standard queen size bed is 60 inches wide by 80 inches long. There is actually a California Queen that is 4 inches longer, but is hard to find. In other countries, the dimensions are different.

Here is a quick rundown of the 6 main mattress sizes, and their respective dimensions:

1. Twin - 38" x 74"
2. Twin XL - 38" x 80"
3. Full - 54" x 74"
4. Queen - 60" x 80"
5. King - 76" x 80"
6. California King - 72" x 84"

The first three sizes are perfect for being used by a single person. However if you are planning to buy a mattress for two, then the last three options are going to give you both ample space for a good nights sleep.
