re: What programming best practice do you disagree with? VIEW POST


80 characters per line is a common one. I feel that this is an old practice from technical limitations that lived on. I do not go overboard with extremely long lines of code, but with widescreen monitors, 80 characters seems a bit limiting.


If I remember correctly that stemmed from the COBOL era where a punch card only had a certain number of characters across plus a blank column (the fourth I think?) for the sorting wheel to put cards in order.

I don't think I've ever adhered to a certain number of characters in C#.


Plus, in the 80s graphic cards the standard text mode was 80 columns X 24 lines.


My coworkers use huddled terminals in an i3 workspace and with Vim, they appreciate having 80 characters per line.


same here, 80 chars are visible in 3 columns at 1080p; and also 1 vim column + browser without triggering the "small screen websites format". By the way, i3 + nVim is perfect


I prefer 120 characters, and stay pretty strict on that limit. 80 chars definitely is not enough, but I do like having a hard limit on line length.


Erm, nobody insists on that anymore so no, not common at all - it's long been revised to 120.


Like everything else about JavaScript, This limit is regressive at best.


I think 80 is just for encouraging good practices. Some people tend to ignore soft recommendations like "don't go overboard", but will follow hard limits.


I appreciate code that has an 80 char limit, means I can put two code panes next to each other without having to put the font eyebleedingly small


It's not just a technical issue. longer lines are harder for the human mind to parse out. In text, 50-60 characters are ideal. I think more than 80 in code is pushing it. Having said that, I agree that it's not something to be too dogmatic over. We have our linter set to 125 cpl.


I'm pretty fond of 80 characters being the limit.


I have heard of the 50-60 being ideal, but I thought that was more for reading sentences than text in general. I could be wrong though, I haven't looked at the studies on it.


It has another use case: showing code on a presentation (you need to increase the base font size) keeps your code formatted and in the screen.
