How to change the line height of a font
I want to change the "line height" of a font, that is the space between lines when the font is typed. I'd like to increase the space. (I need to use several fonts font in a text app with a fixed (non editable) line spacing).
I'm not very experienced with fonts. I do have Fontographer, and I tried several things like changing the "base point" but it seems to have no effect.
Note: This answer is a transliteration of my comment above for the sake of having an answer. MrWolfy noted that changing the UPM size in Fontographer was the equivalent of what I was speculating.
Any glyph in a font is set in an invisible square called an "em-square" or "em-height".
Increasing that might increase your leading (line height).
