I have a document, where I want two versions: one versions 10pt size and another version, 2 page to a side 12pt. So I currently have:

\documentclass[10pt,a4paper,oneside,openany,article]{memoir} 
\newif\ifprintver
%\printvertrue

\ifprintver
\usepackage{pgfpages}  
\pgfpagesuselayout{2 on 1}[a4paper,border shrink=1mm,landscape]
\fi

But I have to change the font size by hand. What can I put inside my \if that would change the font size document wide?

You can define your printver boolean before \documentclass and then use \documentclass inside an \ifprintver conditional:

\newif\ifprintver
%\printvertrue

\ifprintver
\documentclass[12pt,a4paper,oneside,openany,article]{memoir} 
\else
\documentclass[10pt,a4paper,oneside,openany,article]{memoir} 
\fi

% ... other code

\ifprintver
\usepackage{pgfpages}  
\pgfpagesuselayout{2 on 1}[a4paper,border shrink=1mm,landscape]
\fi

\usepackage{lipsum}

\begin{document}

\lipsum[1-100]

\end{document}

  • Nice solution, but you should swap 10pt and 12pt in your code example.

  • @lockstep: thanks for noticing, I've made the change.

  • I'm beginning to learn that "the first line in your .tex file must be a document class" is a LIE!!!! Thanks for this.

The KOMA-Script-classes feature the macro \changefontsizes which allows you to change the main font size mid-document. This macro is also part of the scrextend package, which can (or at least it seems so) be made compatible with the memoir class.

\documentclass[10pt,a4paper,oneside,openany,article]{memoir} 

\makeatletter
\let\@textsubscript\relax
\let\setfootnoterule\relax
\let\multiplefootnotemarker\relax
\makeatother

\usepackage{scrextend}

\newif\ifprintver
\printvertrue

\ifprintver
\usepackage{pgfpages}  
\pgfpagesuselayout{2 on 1}[a4paper,border shrink=1mm,landscape]
\changefontsizes{12}
\fi

\usepackage{blindtext}

\begin{document}

\blindtext

\end{document}

  • Should be noted, that the correct way to do this is \KOMAoption{fontsize}{12pt}. changefontsizes is for calculating relative sizes like footnotesize for non-standard base sizes. Meaning the calculated values overwrite the default/standard values. But changing the fontsize means recalculating the type block. memoir has its own commands to deal with that.

use a variable for the font size setting, e.g.

\documentclass[\FontSize, a4paper]{article}

and then run pdflatex with

pdflatex '\def\FontSize{12pt}\input{<your_file>.tex}'

now you can simply change the fontsize

  • You could also use pdflatex '\PassOptionsToClass{12pt}{article}\input{<your file>.tex}'

I am not sure if it is a good idea, just to set the font-size. There are more subtle differences, such as setting equation number sizing etc. What LaTeX does when processing the options is that it imports a file with the sizing and other related definitions with the extension .clo. You can try this:

\input{size12.clo}

For each class LaTeX uses slightly different conventions, for example in the book class, it uses bk10.clo.

    The .clo files use \newcommand, so you have to undefine all of the sizing commands before this works.
