Applescript to set terminal window to specific size
Scaled-down values need to be given to osascript. You'll need to experiment as CJK said.

In my case, I want a size that is the same proportions as HD (1920x1080), but maximize my screen width. I made my Terminal the full width and height of the screen (manually, not with the "full screen" button because I want to preserve the menu bar). Then ran:

osascript -e 'tell application "Terminal" to get bounds of front window'

=&gt; 0, 23, 1440, 900



So, it looks like the menu bar is 23 pixels, and the width used by osascript is 1440. 1440 width in an HD ratio is 1440x810.

So, the command for me that results in a max width window that is HD ratio is:

osascript -e 'tell application "Terminal" to set bounds of front window to {0, 23, 1440, 833}'


The 833 is 810 + 23 to account for the menu bar height.
