I couldn't express myself. I want to know which fontsize I have to select when I resize my form. Sample:

my form's size is 300x400 my font is 9

I resized my form to 400x500 and my font should be ???

I resized my form to 500x700 and my font should be ???

is there any formula for that or I have to test by looking with my eyes form ranges.
