I was wondering how I can change the line length in IntelliJ.
Since I use a pretty high resolution, I get that line that shows 120 characters straight through the middl
You can alter the "Right margin" attribute in the preferences, which can be found via
File | Settings | Project Settings | Code Style - General
Right Margin (columns) In this text box, specify the number of columns to be used to display pages in the editor.

I didn't understand why my this didn't work but I found out that this setting is now also under the programming language itself at:
'Editor' | 'Code Style' | < your language > | 'Wrapping and Braces' | 'Right margin (columns)'
It seems like Jetbrains made some renaming and moved settings around so the accepted answer is no longer 100% valid anymore.
Intellij 2018.3:
hard wrap
- idea will automatically wrap the line as you type, this is not what the OP was asking for
visual guide
- just a vertical line indicating a characters limit, default is 120
If you just want to change the visual guide
from the default 120
to lets say 80
in my example:
Also you can change the color or the visual guide
by clicking on the Foreground
:
Lastly, you can also set the visual guide
for all file types (unless specified) here:
File > Settings... > Editor > Code Style > Hard wrap at
File > Settings... > Editor > Code Style > Right margin (columns):
It may be useful to notice that very good answers given above may not be enough. It is because of one more tick is required here:
Be aware that need to change both location:
File > Settings... > Editor > Code Style > "Hard Wrap at"
and
File > Settings... > Editor > Code Style > (your language) > Wrapping and Braces > Hard wrap at
