I'm using a theme for beamerposter that requires the package lmodern. Specifically, I'm modifying the theme found here. However, the displayed equations do not look right when I use lmodern.

MWE:

\documentclass[final]{beamer}
  \usepackage{lmodern}
  \usepackage[english]{babel}
  \usepackage{times}\usefonttheme{professionalfonts}
  \usepackage[orientation=portrait,size=a0,scale=1.4,debug]{beamerposter}   
  \begin{document}
  \begin{frame}{} 
    \begin{block}
      \centering
      {\VERYHuge $\sum_k^\infty$}
    \end{block}

  \end{frame}
  \end{document}

The sigma for the \sum here is tiny. It looks normal if I do not use the line \usepackage{lmodern}. It also works fine if I use lmodern in beamer without beamerposter.

  • I had this very problem (my poster didn't use the package "lmodern," but it did use the theme "confposter" which seemed to mess up the scaling.) The "exscale" thing didn't work for me; the only solution I found was to use "graphicx", as described by Qrrbrbirlbel in this post: tex.stackexchange.com/questions/22773/… This worked perfectly for me :D

This is the normal (in the sense of systematic) effect on large mathematical symbols when using lmodern. You should try with \usepackage{exscale} after lmodern.

Interesting. May I suggest you may want a package that supports math typesetting, like mathptmx, instead of times, which does not?

    I'd rather suggest \usepackage{newtxtext,newtxmath} or the MathTime Pro Lite (requires non standard installation).
