The small font option is not enough if you use 144DPI.
So, after choosing and trying bad the small fonts option:
Download my 2 files pack,
. put the 2 files in \GameData,
. erase Fonts120.ini
. rename Fonts144DPI.ini to Fonts120.ini
(Fonts120DPI.ini is your backup file of original Fonts120.ini)

edit: You may need to decrease the resolution of the game,
so the fonts fit the game windows, but don't appear too small.
Example, my monitor is 1920*1080 pixels, but I set the game to 1600*900.
edit2: On my other pc (portable), I too need the file,
but I let its 1600*900 resolution, I don't decrease it.
