Hello steely1.
Increasing monitor and game resolution (Video Settings on clipboard) reduces the text size of everything. 1280 x 1024 will look smaller and tighter than 800 x 600. One note: if you change game video settings from the clipboard, be very patient. It may seem like the game is frozen, but it will eventually change.
Adding anti-aliasing in the settings for your video card will change the look of text also.
