DIN for the win
The font, not the institution as the standards are fucking expensive
There are a lot of important standards. The hight of a door lever, a light switch or an average stair for example.
Yes, and many are very old. Like 1920-ish old. So they slightly update them and invalidate those that become public domain. They are systematically milking standards for money and making it harder to enter industries legitimately. Maybe more money-burning start-ups and their investors would care about standards if the red tape wasn’t behind a paywall. Now they just wing it and hope to IPO before their violations cause loss of life a public image problem.
There are actually B, C and D formats with the same properties, just scaled up or down slightly if you need something in between, for example B4 is basically A3.5, C4 is A3.75 and D4 is A4.25 if you plug it into the power-of-2 formula. (Later, C and D were removed because very few people used the quarter-steps.)
