Often my students want to look at my lecture notes on their phones. Obviously no one wants to do that routinely, but it is often convenient if you do not have a paper copy to hand and you just want to look up an isolated fact. I have A4 size pdfs on the web, which one can just about read on a phone, but it is quite awkward. Does anyone have a good set of options that they have tested for generating phone-readable pdfs from LaTeX?
