When I read on a computer, my ideal width seems to be around 1/3 of a 1080p monitor. I usually have my browser window sized at about 2/3 of the screen width. On phone, most sites that have even a remotely responsive design are easy enough to read. I've also read at least a dozen Epub format books on my phone in the past few months, and frankly the convenience has got me back into reading in a way I haven't in years. My reader renders text as orange(ish)-on-black, and the big thing is I can read in bed at night without disturbing my partner (whereas even a small book light was disruptive). I've read mostly fiction but nothing like scientific papers, so I'm not sure how that translates, but definitely I find it's a good reading experience. It's also easy on the eyes on a way black-on-white PDFs cannot be. The key though with all of this is that the text is formatted appropriately for the medium. White backgrounds on backlight screens are just as hard to read as if you had white text on black paper. I don't doubt it's hard to isolate the effects of format and medium, but they're tied in a way that you can't ignore one and study the other, imho.
