How to change line width in IntelliJ from 120 character

Question

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 middle of the screen  Can I change it from 120 to  say  250

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
