How to set max line length rules in view? (not linting)

I am using Webstorm 7 and want to set a max line length in the view to be 80 and not 120 (as the default ruler is set to).

I've searched all over and the closest I can find is the JSLinter (https://www.jetbrains.com/webstorm/webhelp/jslint.html) but I cannot seem to see how to actually change the ruler in the IDE.

Question: How do I set the ruler for the line length in Webstorm 7?

Solution 1:

Settings > Editor > Code style > Hard wrap at [...] columns (default is 120)

Solution 2:

Quite late to the party and wrong version of Webstorm. But I got sent here by Google and in latest Webstorm (version 10) this option has been moved to Preferences > Editor > Code style - Right margin (columns).

Hope it helps someone.

Solution 3:

The location to set the line length changed again.

Update: Still valid in 2021 for PhpStorm 2021.2.2:

Settings > Editor > Code style - Hard wrap at || Visual guides

If the ruler doesn't show up at all, check that it is enabled:
Settings > Editor > General > Appearance - Show hard wrap guide
