doogiet:

By "size of the chords", I assume you mean the chord names (C,Gm7 etc.) and not the guitar chord symbols.

Also assuming you're using BIAB 2016.

Try this:

- From the main BIAB screen, click the "Lead Sheet" button.
- Click the "Opt." button in the top LH corner of the screen
- In the Lead Sheet Options window that opens, try different settings for the "Font Size" option (say, "124%" - mine then displays 125% for some reason).
- Now click on "Notation Options" at the top of the same window
- In the bottom LH corner, change the "Chord Font" size to (say) 200%
- Then select OK and OK again
- The result may look ugly on the screen. Just ignore it.
- Click the "Print" button in the top LH corner (not to worry, it won't print yet)
- Then click "OK Preview/Graphics"

Mine shows fairly large (I'd say ~24pt) chords sitting right on the top line of the staff. Yours may vary.

Let us know what you come up with and if you get what you're after.
Someone here will likely be able to provide further insight.

Good luck!
