It blows our hivemind that the United States doesn't use the ISO 216 paper size standard (A4, A5 and the gang).
Like, we consider ourselves worldly people and are aware of America's little idiosyncrasies like mass incarceration, the widespread availability of assault weapons and not being able to transfer money via your banking app, but come on - look how absolutely great it is to be European:

Instead, Americans prostrate themselves to bizarrely-named paper types of seemingly random size: Letter, Legal, Tabloid (Ledger) and all other types of sordid nonsense. We're not even going to include a picture because this is a family-friendly finance blog.
Pretty much the same is true everywhere else though. A4 is just extremely common. All documents are printed in A4.
But if you want another size for a sign, blueprint or maybe a postage sticker it's easy to get another size.
If you want A5 just print the same thing twice on an A4 and cut it in half after or cut the paper in half first and then print on it.
If you want A3 you will obviously need a bigger printer (or you just tape two A4 together if it doesn't need to look good.)
I think I screwed up the assignment somewhere? For some reason the tape sticks to my letter sheet but not my A4 sheet and my construction paper crayon drawing is still too big for them to create a proper border?
Well that solves it if WOTC used it then we need to get rid of it. Burn it in a fire. And we'll need a new standard now. We could use the ISO standard but Western Union just handed me a thousand bucks to base it off telegram cards. Oh well.
i mean, i've never needed to divide the size of a standard sheet of paper - if i need a smaller variant, i can just fold it in half and cut it. when working with paper, it's pretty easy to do physical math, and you rarerly need something that's perfect down to the millimetre
regarding the size- it's just something you learn through life. school supplies lists typically specify the size of notebooks and paper you need to buy in centimetres, so year over year, you quickly learn that A4 is 22:29.7, and the slightly bigger standard notebooks are 24:32
