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:
The American mind cannot comprehend this diagram

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.
Wait, the US genuinely doesn’t use A4 etc.?
We have trouble fitting all our freedom on your kooky, internationally-recognized sizes
Here’s a comparison using the most sensible units possible:
Do Euro printers say PC LOAD A4?
I think they probably do.
I want to only briefly defend the NA system in terms of naming. I get it, I worked in printing for decades, I know how shitty it all can be. But Letter and Tabloid communicate well for something that is otherwise all the fault of press guys.
Well, it’s 2024, so they mostly say things like “out of A4 paper - load A4 paper in tray number 3”. But yeah, they used to.
Let’s not even start with the metric system (used everywhere) and the imperial system (used in the usa and some african countries).
The best part is the US Military and NASA both use metric. I love that fact.
Except for the UI.
During the Apollo program they had very limited computer capacity in the capsule and lander. Computers were huge machines back then and they had to fit one in a spaceship.
The Apollo computers used metric internally for all calculations. Anything shown to the astronauts however was in imperial, as metric was apparently too complicated for astronauts to comprehend. They had to waste precious computer capacity converting to imperial because even astronauts can’t handle anything else.
The annoying “letter” paper size is for some unknown reason what windows always sets as the paper size unless I change it to A4 manually. Naturally if I forget the printer won’t print. US paper sizing - annoying me on the other side of the Atlantic.
Aside from the 1 to √2 ratio, the area of A0 paper is exactly 1m². People behind ISO 216 thought of everyting.

how to make a good standard:
step 1: copy from DIN
Well, Germans are pretty anal about standards (thankfully) and they do them right, so why not copy them?
From their website: “We’re ISO, the International Organization for Standardization. We develop and publish International Standards.”
Sadly, ISO in recent decade started to do bullshit. They don’t pay for standard development, they don’t employ anyone for standard development, they collect membership fees from national standards organizations, require payment to download most standards and don’t allow to copy published standards. Also they retroactively paywalled a lot of standards.
