Lyrics displayed are so tiny. How to make bigger?

When I insert lyrics manually via UNSYNCEDLYRICS, the output is so tiny when I play the song on my pc (XP and Win7). How do I make the fonts larger, say size 24 or 32?

You would have to twiddle with the OS's standard font settings. I doubt that any coding e.g. RTF or HTML would be interpreted.
Or use the screen magnifying tool that comes with the OS.
