I tighten mine up slowly to give the horse time to acclimate, then when I think I'm done I stand facing the girth square, tuck the tips of my fingers under the girth on both sides (in front of and behind it) then give a good tug with both my hands. If it gives a bit then that's where I like it, if I feel like I'm going to fall over from lost balance after my tug then its too loose and if it doesn't move at all then it's too tight for my liking.
Sorry, I don't really have a "finger" rule, I just do it by feel.
I always like to remember that the girth will loosen up when you put your weight in the stirrups, so if its already on the loose side before you get on, its going to be way too loose when you get up there.
