Size of screen diagonal?

I'm not really sure how you would go about this.

For instance: I have a 2006 iMac that uses both its in-built monitor and 
another second one.

System Info tells me that my in-built display is 20.1 inches, but 
nothing about my other one
beyond the fact that it is a VGA display.

However, my Xubuntu machine does report the dimensions of the monitor
connected to it accurately (NEC Corporation 21").

I'd like to display them at real size but I can't find the properties for the current screen (i.e. the one that my app is running on.  I can get the screen colour depth, resolution, scaling factor, etc. but not the physical size on the screen such as "27 inch diagonal" or physical px per inch.
