Obviously, smaller is better for web fonts. Mine are rather big due to the large number of glyphs, but then that also makes them more versatile.
I did a test with my font using the various export options:
- Postscript Names + Hinting = 368 KB (376,857 bytes)
- No Postscript Names + Hinting = 344 KB (352,845 bytes)
- No Postscript Names No Hinting = 293 KB (300,213 bytes)
- No Kerning Tables Either = 282 KB (288,937 bytes)
Can web fonts make use of kerning tables? Hinting is presumably useful, while postscript names are probably not.
