I'm converting my design portfolio to a PDF so that I can show it on a tablet (which I've yet to buy so not sure which one I will have which doesn't help matters), and I am not sure if I am being a bit dim to not know what size of Indesign file to start setting it up in. I can't trial and error at the moment as no tablet to play around on. Also do tablets have that automatic rotation that a lot of phones have? I'm not sure whether it's best to do it portrait or landscape and what the proportions are. Sorry if this is a stupid question. I am trying to get my head around it and not sure if I'm having a brain fart!
