By default org mode seems to configure 8x11 as the paper type when I export to latex. I always print to A4, so I would like all of my exports to specify a4 as the paper type -- e.g.:


I currently solve the problem by putting the following line in my file whenever I want to export, but that's pretty redundant:

#+LaTeX_CLASS_OPTIONS: [a4paper]

How can I tell emacs to do this whenever I run latex export?

  • I believe that the default is taken from the default LaTeX clas, i.e. #+LaTeX_CLASS: article I think. See the value of org-latex-default-class to figure out what it is. – wvxvw Sep 23 '15 at 11:18

You need to configure the org-latex-classes variable. Normally something like the following does the trick:

(add-to-list 'org-latex-classes
         '(("article" "\\documentclass[11pt,a4paper]{article}"
            ("\\section{%s}" . "\\section*{%s}")
            ("\\subsection{%s}" . "\\subsection*{%s}")
            ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
            ("\\paragraph{%s}" . "\\paragraph*{%s}")
            ("\\subparagraph{%s}" . "\\subparagraph*{%s}"))))

However in this case there is a default class called article. Editing that entry in the list is a bit non-trivial. So I suggest just creating your own, say a4article. Just replace the "article" in the above example with "a4article". You can find many other examples in my Emacs setup.

  • Is editing inplace necessary? One can usually push a new element to the almost and the older one will be ignored – YoungFrog Dec 5 '16 at 5:58
  • I'm not sure I understand the question, do you mean, why not add a duplicate "article" entry in org-latex-classes? As it's a list, duplicate entries can lead to unpredictable behaviour. If you rather edit in-place, have a look at my emacs setup (link provided in the answer), there are some examples for that as well (for a different org-latex variable). – Quarky Dec 8 '16 at 6:17
  • I mean that this variable is documented to be an "Alist" (I just checked). When searching an association list for an association with a given key, the first one found is returned, if there is more than one. (see (info "(elisp) Association Lists")). – YoungFrog Dec 8 '16 at 20:34

    There are too many brackets around the second argument of add-to-list. Should be (add-to-list 'org-latex-classes '("article" ... . – Timm Apr 28 '17 at 16:47
