I have been using LaTeX, and I have just checked that the memoir class doesn't allow me to uso the Garamondx 13pt ... just 9,10,11,12 and 14pt.

I have printed my book "prototype" and 14 seems a little too big.

Is there a way to set a 13pt font size?


According to the user guide of the memoir package, the following default font sizes (in points) are provided: 9, 10, 11, 12, 14, 17, 20, 25, 30, 36, 48, and 60. For each of these sizes, a file called mem?.clo ìs provided, where ? can be 9, 10, 11, etc and clo stands for "class option". One needs to set the document class option extrafontsizes for font sizes that exceed 25pt.

For new font sizes, e.g., 13pt, you'll have to set up a file named mem13.clo along the lines explained in the user guide. For the case of 13pt, I'd like to suggest you use mem12.clo and mem14.clo as "templates" and, specifically, average the values used in those two files for the new file.

Addendum: Here's my attempt to create mem13.clo as a convex combination of the parameter settings used in mem12.clo and mem14.clo. Save it either in the directory that contains your main tex file or in a directory that's searched by your TeX distribution. If you choose the second option, do also perform a refresh of the filename database of your TeX distribution.

And here's an MWE that makes use of this new class option file. (Incidentally, I think the sizing command should be named \minuscule rather than \miniscule...)

  • I am relatively new to LaTeX...I regret to say I have never done this before....Where can I find this files for using as templates? – Adriano May 17 '16 at 14:38

    @Adriano at least on Linux you can put the .clo file in your ~/texmf (equivalent to /home/<username>/texmf) directory and do a texhash ~/texmf <Enter> at the command prompt. This is a wonderful answer, and I know a lot of work went into it. – A Feldman May 18 '16 at 2:48

    @Adriano - You could use the kpsewhich utility from a command line to locate any file of the TeX distribution. E.g., kpsewhich mem12.clo will return the fully qualified path name of mem12.clo. – Mico May 18 '16 at 7:26

    @Adriano - Not knowing your computing environment, I can't comment knowledgeably. Have you seen the LaTeX editors posting? – Mico May 23 '16 at 17:41

I have searched about it... This package do the trick.

    Is it safe to do this with Memoir? – cfr May 17 '16 at 13:35

    Well, this answer is a really bad idea. Even if it seems superficially to work right now, the chances that it will cause trouble are extremely high. Moreover, the kinds of problems caused may well be deeply mysterious and difficult to diagnose. – cfr May 17 '16 at 15:00

    Do not use any koma package with memoir. Adriano, use the solution that Mico provided to you. – Peter Wilson May 17 '16 at 17:56
  • I will leave this one here, it may be useful for the ones who have the same idea to know that it is not recommended. – Adriano May 19 '16 at 20:27
