[Tex/LaTex] How to change the default height of pages and frames in Beamer

beamergeometry

In the Beamer class, is it possible to change the height of a page and frame?
I'm producing a document for web display and would like it to be on a continuously scrolling format so I would like to have frames with height 4 times taller than the current default height. I tried something like the MWE below but I get "Missing \begin{document} error"…

  \documentclass{beamer}
  \usepackage[papersize={12cm,30cm}]{geometry}
  \begin{document}
   \begin{frame}{test}
   \end{frame}{test}
   \end{frame}
  \end{document}

Best Answer

The default page/paper size under beamer is 12.8cm wide and 9.6cm tall - a 4:3 ratio - set by geometry.

If you want something different just set it using \geometry{..}:

\documentclass{beamer}
\geometry{papersize={12.8cm,38.4cm}}
\begin{document}
\begin{frame}{test}
test
\end{frame}
\end{document}
