So one of the huge annoyances of Pages for iOS is that there are only 2 paper sizes (letter and A4) AND that the document must be in portrait. But!if you create a different sized document in landscape with Pages on Mac and open it on your iPad or iPhone, Pages for iOS will respect the size and orientation of the document.
Well, I want to create a bunch of "templates" of commonly used paper sizes for you all and wanted to know which ones you'd like to see included in the list
Tap your screen once after it opens in Safari. You should see two buttons overlay the document in the upper right hand corner. One is to open in pages, the other is to open in any other supporting apps you may have.
seriously, if I could I would give you a big old' hug and a kiss for doing this. I've replaced my Mac with the new iPad so there's not a way for me to get around this problem...other than you, you beautiful, wonderful person you
