There is an experimental type of reading called rapid serial visual presentation, which uses a screen only one word wide. As small as a postage stamp. Your eye remains stationary, fixed on one word, which replaces itself with the next word in the text, and then the one after that. So your eye reads a sequence of words “behind” one another rather than in a long string next to one another. A small screen only one word wide can squeeze in almost anywhere, expanding the territory of where we can read.
