Yes, I find it harder to read code at lengths much longer than this. 120 is quite difficult. It also makes it even harder to read if you split the screen vertically, which I do all the time.

That said, I don’t think it should be a hard limit and it’s fine if a lines a bit over, +/- 10 like you said. Certainly not something that we should contort into multiple lines just to keep under a hard limit. Unfortunately, a few auto formatters only do hard limits - it’d be interesting to see how an acceptable interval around the limit would work.

Plus, I’ve noticed the limit makes more of a difference for comments than code so I try to keep comments under that. The written word appears more sensitive to line length.
