Is it possible to change the paper size of some frames in beamer? I know you can change the global paper size using \geometry{paperwidth=,paperheight=} in the preamble, but assuming you want to change the size for one or a couple of slides only, how would you do that? The above command only works in the preamble.

    I'm wondering why you want to change the slide size and not, say, resize the image to fit on the current slide size. Wouldn't that be a better option? Any slide resizing is going to get scaled back to screen size for presentation. – cbowern Oct 24 '13 at 15:58
  • You can change \pdfpagewidth and \pdfpageheight between frames, which should change the "paper size". However, it will only produce a regular-sized frame on a larger page size. So many other things have to be adjusted as well to yield a correct result. Why do you want this? What about the suggestion to reduce the size of the components (scale) themselves? You can also use the zoom feature of beamer... – Werner Oct 25 '13 at 4:56
  • I have the same question, not to fit an image but to resize beamer's slide size. I want it to be 13cm width and 10cm height. I used \geometry{paperwidth=13cm} in the preambule and worked, but not the same for paperheight. – hkviktor Dec 11 '14 at 16:26

    @hkviktor I think that's a different question. If you want a different size for all slides, take a look at Beamer's documentation: it tells you how to do this. Beamer already loads geometry so some care is needed to ensure that your settings override the defaults correctly. Geometry is a bit weird and doesn't always behave as you think it should. (How I think it should, at least.) – cfr Nov 7 '15 at 23:08

Broadly 'no'. You can use \newgeometry between frames

\documentclass{beamer}
\begin{document}

\begin{frame}{Some text}
  Some text
\end{frame}

\newgeometry{a4paper}

\begin{frame}{Some text}
  Some text
\end{frame}

\end{document}

but beamer does not 'know' about this and frame decoration will end up in the wrong place. Moreover, given the target of beamer (making presentation slides) it's hard to see how such a change can be meaningful.

A very dirty hack could be to manipulate \pdfpagewidth and \pdfpageheight, as suggested by Werner.

However this does not adjust things like the \textwidth - a quick workaround for this is to place the frame content into minipages of appropriate widths.

\documentclass{beamer}
\usetheme{Berlin}

\usepackage{lipsum}

\begin{document}

\begin{frame}
content...
\end{frame}

\pdfpagewidth 21cm
\pdfpageheight 29.7cm

\begin{frame}[plain]
\vskip1cm
\begin{minipage}{19cm}
\lipsum
\end{minipage}
\end{frame}

\makeatletter
\pdfpagewidth \beamer@paperwidth
\pdfpageheight \beamer@paperheight
\makeatother

\begin{frame}
content...
\end{frame}

\end{document}
