100 is OK. But better to wager for 80, so people complain about their preferred 120+, and ending up with an acceptable 100 as a middle ground.

On my screen with 1920x1080, 2 side-by-side panels can fit 100 chars, but only if the sidebar is hidden (project layout, list of open files, that kind of stuff).

On my laptop, 2 side-by-side files won't fit if they exceed 90 chars.

I just don't want to concede to those devs who use a single editor pane with an ultrawide monitor, and believe that everybody must work like they do.
