A series is just so practical and simple. Cut a A0 sheet in 2 at the center of the long edge, you get 2x A1, repeat you get 4x A2, etc. This also simplifies production.
The Americans haven’t been alright since pirates captured the reference kilogram on its way to the newly independent USA from France, and they sour-grapesed themselves into making wilful archaisms part of their identity.
Don’t forget choosing transmission errors and telling the rest of the world they are saying the name of a metal wrong.
I never would have believed Canada to be on the dark side of paper formats.
It sucks, trust me…
I would like to change to A4 paper, but in Canada? Good luck even finding it. Staples carries 1 SKU and at $28 for 500 seets it’s 4x the price of other paper.
The biggest advantage of A4 isn’t explained clearly: since it follows √2 ratios, you can reduce by half and get it to fit exactly 2 pages of information on 1 sheet, so you can make any document into a 2-per-page booklet with perfect formatting.
If you try to print 2 pages per page with US Letter, you get massive waste and it looks terrible.
The A series is better because it divides easily into smaller sizes, shows more on phones, and portrait monitors.
I like my A sheets, but no paper format is good on screen, it’s a whole different medium.
