80-85 is what I prefer. I&#x27;ve worked at places where the style guide said 100, but j still kept my lines below that. 100 is too many characters on one line.<p>Standard typographic convention is 2-3 alphabets on one line. It doesn&#x27;t quite apply with a mono space font, but 3 alphabets is 78 characters.<p>When I&#x27;m writing hard line wrapped prose, I even prefer to keep it to 72.
