My daughter is in high school and is working on a science project. She has really enjoyed writing the paper in LaTeX. Now, she has to make a tri-fold presentation of the major points. In the past, that has meant PowerPoint printed onto letter-size paper then pasting those pages (one slide per page) onto the board. How can we resize beamer to have at least the same aspect ratio as letter-size paper? Ideally, we would have the same dimensions, also, but that is not so important as we can scale at print time. I have used beamerposter in the past, but that generates just one page, I think. Any suggestions are appreciated. The default is to simply use beamer as-is and scale to as close to letter size as possible when printing.

    If you want those fancy color and box stuff provided by beamer, beamerposter is the right choice. If you want something less fancy, just take a "default" class. Build-in aspect ratios for beamer are 16:10, 160mm by 100mm; 16:9, 160mm by 90mm; 14:9, 140mm by 90mm; 5:4,125mm by 100mm; 3:2, 135mm by 90mm and of course 4:3

The beamer class sets paper height using geometry, so while there isn't an interface to override the settings you can just force the issue after loading the class.

\documentclass{beamer}
\geometry{letterpaper,landscape}
\begin{document}
\begin{frame}
  Hello world
\end{frame}
\end{document}

If you want the aspect ratio without the full page size then you'll need to work out the papersize yourself. For example, the standard beamer settings have a paper height of 9.6 cm and width of 12.8 cm. Keeping say the width the same we might do

\documentclass{beamer}
\geometry{papersize={12.80cm,9.91cm}}
\begin{document}
\begin{frame}
  Hello world
\end{frame}
\end{document}

Here, as I've hard-coded the sizes I don't need the landscape key.

  • Can we teak this to handle 17in. x 22in. size paper or for that matter a poster size?
