It's far simpler for an American because soda in the US is widely available in three sizes:

* 12 fl oz (355 mL) aluminum can

* 20 fl oz (591 mL) plastic bottle

* 2L plastic bottle

Depending on the brand and store availability I've also seen 12 fl oz glass bottles, 1L bottles, and sometimes smaller sized cans as pretty standard sizes. Other types of drinks (such as energy drinks) can vary in what containers they use.

In general, though, if you're buying soda for a family or for more than one drink/meal, you're going to be buying a 2L bottle (and refer to it as such).
