Here’s a case for 80rule: our vision is (mostly) two dimensional, research shows reading comprehension drops as lines get longer, that’s why books and newspapers mostly have fairly narrow columns, comprehending code is less about reading but more about scanning and picking up context for things, much easier to do when perimeter is minimized. Lots of gut instinct here, not enough citations, maybe one day I’ll compile a more substantiated post about this.
