Hello,
I can’t get the chord symbols’ accidentals bigger.
I went to Engraving options / Design /
Scale factor for stacked alterations: 99 %
but it doesn’t appear to change.
I read some threads on the forum but they didn’t fix my problem.
It might be related to the fact that I use the font Arial.

Font Styles > Chord Symbols Music Text Font isn’t the same size as Chord Symbols Font
It seems to look better once they match up.
Thank you for your reply.
I tried to use Arial as Font Styles > Chord Symbols Music Text Font
But it doesn’t recognize accidental.
I might misunderstand something with the chord fonts system.
Did you check the size matches with the Chord Symbol Font (which is directly above in the Font Styles list)?
You can’t use Arial as the font for “Chord Symbols Music Text Font”. It needs to be a SMuFL-compliant music font, such as Bravura or Petaluma (or any number of third-party SMuFL-compliant fonts).
Thank you dspreadbury
In Font Style, I set the Bravura font for :
Chord Symbols Font
Chord Symbols Music Text Font
to control the size of the #
Chord Symbols Altered Bass Separator Font
For the size of (add9)
I went to the Engraving Options
factor for subscript and superscript components
But When I tried the Petaluma for Chords and Rehearsal Mark
it doesn’t seem to change the font but the square around the Rehearsal mark is strange.
I tried the Petaluma Script font style,
and the font of the chords changed but I lost the sharp of the chord c#m (add9)
Using the Rehearsal Petaluma Script fixed the square enclosure.
Using Petaluma text solved my # problem but for me the difference between
Petaluma, script and text is not clear
