The designations such as “A2” do not correspond to ISO paper sizes.
As with the paper sizes don’t let the number of figures above confuse you. In the end we tend to use quite a small number of different sizes. You may want to refer to these charts when buying evelopes off companies or ebay etc. Having said that most of them are good at giving the measurements rather than just using the name.
