From what I have gathered on the interwebs, I found that beamer gives no basic options to change the papersize. I am however in desperate need of exactly that. Mind that I don't want to re-scale one or more frames to an A4, I want to actually change the size of every frame.

Is there any way to work around this?


@JosephWright The reason I need to change the paper size is because I need to end up with the different slides in PNG format. These png's have to be a certain size. I was planning on simply converting the pdf to png's like you could normally do with LaTeX, untill I found out the problem with resizing in beamer.

@ prettygully I have already looked at the beamerposter package, but it seems like beamerposter puts all the frames on one page, what would make the conversion to PNG's impossible


@ Andrew Stacey Your answers solved my personal problem as I was unaware of aspect ratio and my own ratio happens to be incredibly close to 16/9. I will correct the dimensions during PNG conversion.

I am still interested if anyone can come up with a general answer to the question thought.

  • beamer reduces the size of the "paper" in order to increase the effective font size. It is actually assumed that the PDF is zoomed to fullscreen or to the full paper size. To zoom it yourself check pgfpages (not to be confused with pdfpages, even if this might also be a way)

  • you can change the aspect ratio; otherwise have a look at the beamerposter package May 11 '12 at 7:01
  • It might be handy to know why you need to change the paper size in this way.

  • For the aspect ratio, see section 8.3 in the manual. May 11 '12 at 7:08
  • Regarding the edits: PDFs are scalable so can be converted to PNGs at any size without loss of detail. The conversion program should have options for specifying the resolution (sometimes called dpi). So you don't need to change the paper size for that (though you may want another aspect ratio).

The class beamer uses the package geometry to setup the page dimension. The package geometry provides the command \geometry to set options in the preamble. So you can simple use:
