Taking for example the Rockwell OTF typeface. There are three "classes" inside of it:

  • Rockwell
  • Rockwell Std
  • Rockwell WGL

Are those particular to this typeface, or they mean something in general when we are talking about typefaces? Checking the glyphs I didn't spot any difference between Rockwell and Rockwell WGL Regular, the only difference is between Rockwell Std and the others, as the first one has less glyphs.


Std means "standard" and can have different meanings depending on the foundry. The difference between Rockwell and Rockwell Std appears to be a difference in symbols included as well as minor differences in letter spacing and line height.

WGL fonts only support Windows Glyph List characters.

For information about other font name abbreviations, I find this list to be helpful.

  • So, using a WGL typeface is preferred over a non-WGL one? There's no need to install both, TypefaceXYZ and TypefaceXYZ WGL?

  • It depends on your usage I suppose but WGL and regular seem the same to me. I can't think of many reasons why you'd need both installed Mar 15 '16 at 20:46
