In the United States 8.5" x 11" is standard printer paper size. In many counties outside the United States A4 is standard-sized paper. I work as a document specialist and I've encountered various sized paper from outside the United States. I believe A-4 size is a little bit longer and a bit narrower than American 8.5" x 11" paper. The member who made reference to the A4 paper was not from the United States.
Hope this helps to eliminate any confusion with paper size.
