# How can I figure out the font used by a class file [duplicate]

I have a document class that isn't as thoroughly documented as I might like, and I'd like to figure out what font it uses. Is there an easy, universal way to do that?

• If you produce some pdf with that class you can check the pdf properties to see the used fonts. – Sigur Dec 16 '14 at 23:51
• If you're referring to the font that is used to generate some output (PDF), then you can following the guidelines in How do I find out what fonts are used in a document/picture? (possible duplicate). – Werner Dec 16 '14 at 23:54
• That does look like a duplicate - didn't find it in my search though. – T.C. Proctor Dec 17 '14 at 0:54

The document

\documentclass{article}
\begin{document}

\expandafter\show\the\font

\stop


puts the following information on the terminal and log

\OT1/cmr/m/n/10=select font cmr10.

showing that article is using the font cmr10 known to latex as

\fontencoding{OT1}\fontfamily{cmr}\fontseries{m}\fontshape{n}\selectfont


Just replace article by any class you wish to test.

• It helps to precede this statement with \wlog{ ... } so you can find it more easily in the log. – Steven Jeuris Feb 14 '17 at 12:47
• @StevenJeuris I was assuming running in interactive mode where \show stops and shows the tex as if for an error message – David Carlisle Feb 14 '17 at 13:50
