Show window dimensions in titlebar in iTerm2
Can't find the correct variable for the title. But if you go to iTerm2-&gt; Preferences -&gt; Profiles -&gt; Session -&gt; Configure Session, you can create a custom menu component with title as \(rows) x \(columns) and it will show the width. I know it's not the perfect solution but will do your job. 



Make sure your status bar enabled is checked.
