Oh, come on. Everyone knows about A3 and A5.
- zinekeller 4y agoFor Americans et al. who don't know: - A3 is (within physical tolerances, anyway) twice the size of A4 - A5 is half the size of A4 - A0 is the biggest size and and has an area of 1 square meter, although it is not a square but instead it has an aspect ratio of 1:sqrt(2) (technically all A-series papers have this aspect ratio because math says it is the aspect ratio that retains itself when halved) - In practical sense, A5 is the smallest pre-packaged A-series paper that I have personally encountered, although I guess someone would chime that they handled A6 (half of A5) or smaller.
- japaneseminisub 4y ago> technically all A-series papers have this aspect ratio because math says it is the aspect ratio that retains itself when halved I never knew this, but that's awesome. Thanks for the info!
- elygre 4y agoNever saw A6 printer paper, but it’s quite common for note cards / index cards.
- realusername 4y agoSure, I meant the imperial sizes in inches, never heard about that before. I assumed A4 was the global standard.
