    A4 paper has those weird dimensions (not a round number in either metric or imperial) because of its aspect ratio of √2, which allows cutting it in half and still retaining the same ratio.

    A0 paper is defined to an area of 1 m², and each subsequent paper number (A1, A2, ...) is the previous paper halved. Therefore A4 paper has an area of 1/16 m², and a √2 ratio, which in no way produces round numbers for the two dimensions!

    • I'm guessing the papersize of the americans have no logic at allmilfhunter
    • ^ None to speak of.Continuity

    • The logic in the US is that the sizes are easily meandered and consistent. We understand nobody cuts them in half to make other sizes.monospaced
    • But the same “logic “ applies to letter size and 11x17.monospaced
    • Paper used to be made by hand, molds it was made from measured 44" x 17" inches. This was used to create (8) 8.5" x-11" pieces, of what became known as letter.imbecile

    • At 2:3 ratio of many cameras, a photo never really fits and A4 page nicely. But on the other hand, I only have to cut 1.8cm off to make it fit, so who cares.SimonFFM
    • √2? That's irrational.i_monk
    • The square root of 2 is a positive real number that, when multiplied by itself, equals the number 2. 1.41421356237imbecile
    • example: a4 is 210mm x 297mm or 1.4142... eh close enoughimbecile
    • it's so rational, it's impossible to do without a calculator :)monospaced
