Random thoughts on paper sizes: An older relative used to say "if a note is smaller than A4 it does not exist". I think it was from long experience of people losing important information when it was printed on a paper size smaller than A4. I try to keep that in mind whenever the frugal homunculus in me wants to print information in smaller formats to save on paper. The standardisation of ISO paper sizes is nice, but it's also an annoying limitation when it comes to folding paper planes (if one wants to do it with small children that are not yet competent users of scissors), because it limits the amount of models that are viable.
