[Tex/LaTex] way to use 13pt as the main document font size with the memoir document class


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?

Best Answer

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...)
