The amount of ounces in a can of soda can vary, but the most common size is 12 ounces.

Here are some other common sizes:

* 8 ounces: This is a smaller size, sometimes called a "mini can."

* 16 ounces: This is a larger size, often called a "tall can."

* 20 ounces: This is even larger and might be considered a "jumbo can."

It's always best to check the label of the specific can of soda to know its exact size.
