# How to change the default height of pages and frames in Beamer?

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}

• The beamer manual clearly states that one should not change the 'paper' size. Perhaps you're looking for something like beamerarticle etc. – user31729 Sep 20 '15 at 16:54

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}

• Thanks, just out of curiosity: Does Beamer automatically load the geometry package like it does with xcolor or the command \geometry is another animal different from the geometry package? – Sergio Parreiras Sep 20 '15 at 17:23
• @SergioParreiras: geometry is loaded by beamer, so you're using the same interface. – Werner Sep 20 '15 at 18:11
