Aside from the 1 to โ2 ratio, the area of A0 paper is exactly 1mยฒ. People behind ISO 216 thought of everyting.
Which is awesome, because every number up halves the size. This, combined with the standard way that paper weights are given (e g. 80g/m2) allows you to easily calculate how much a piece of paper weights: 1 A4 80g/m2 weighs 5g (1/2^4 * 80g)
Now it makes even more sense!
how to make a good standard:
step 1: copy from DIN
https://en.wikipedia.org/wiki/ISO_216#History
Well, Germans are pretty anal about standards (thankfully) and they do them right, so why not copy them?
The world would be a better place if we copied good things more often.
Imagine all of Europe copied Dutch transportation-, German prostitution- and Portugese drug-policies
oh, I totally agree with you.
In fact standards are made to be copied. That's like the entire point of 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.
