International paper sizes

In the USA, I printed scripts on 8.5"x 11". If it was really important, I'd switch to 11" x 17". For some presentations, we'd mount work on "posters."

In Europe (and, I think, pretty much everywhere else), the standard size of paper is A4.

We'd print on A4. Do story boards on A3, and mount the really important stuff on A1.

Pretty simple stuff. Surprised this isn't used in the U.S.
