Changing the default size of iTerm2 when it opens
The easiest way to have iTerm2 open with a specific size, position and number of windows is:


Get it all set up the way you'd like to see it when it opens. Have all your iTerm2 windows sized and place where you like them.
From the top menu select Window -&gt; Save Window Arrangement and give it a name
Go to the Preferences and under the Arrangements section find the named arrangement, select it and press the Set Default button





Go to the General page and select Open default window arrangement




Now, when you start iTerm2, it'll use your saved arrangement to place, size and create the number of windows you saved. You can adjust the settings any time by placing things as you like them and re-saving the default arrangement.
