The default for exporting to LaTeX from org-mode files is to have the article document class at size 11pt font \documentclass[11pt]{article}.

How do I get the exported LaTeX file to be a specified font size, namely 12pt?

  • Simply: \documentclass[12pt]{article}

  • Tried that it did not work. Upon export it still inserts \documentclass[11pt]{article} at the top and then \documentclass[12pt]{article} further down which doesn't seem to do anything.

Problably the simplest is to add #+LATEX_CLASS_OPTIONS: [12pt] in you file, as discussed in the doc.

The LATEX_CLASS_OPTIONS keyword or EXPORT_LATEX_CLASS_OPTIONS property can specify the options for the \documentclass macro. These options have to be provided, as expected by LaTeX, within square brackets.

You can also use the LATEX_HEADER and LATEX_HEADER_EXTRA2 keywords in order to add lines to the header. See the docstring of org-latex-classes for more information.

An example is shown below.

#+LATEX_CLASS: article
#+LATEX_HEADER: \usepackage{xyz}
