I searched the internet and a big local bookstore for a good resource on designing proportional pitched fonts.
I know there is no fixed rule-book on how the width of a specific glyph or ligature is determined, but are there general rules of thumb or a guideline where to start from?
Which letter does one typically start from? Are there approximations of relationship between different glyphs, e.g. "m" and "n" and "r" or something like that?
Any tips, book recommendations will help. Thank you guys.
