# LaTeX beamer presentation-package 16:9 aspect ratio?

I'm programming a presentation in LaTeX using the beamer class.

However, it defaults to 4:3 aspect ratio slides, while everything I use is 16:9. Is there an easy way to change this using a command or two?

It looks like current version of beamer supports aspectratio option.

\documentclass[aspectratio=169]{beamer}


should do exactly that. Other possible values are: 1610, 149, 54, 43 and 32.

By default, it is to 128mm by 96mm(4:3).

• Hi, could it be possible to have a wide screen aspect ratio for an EEE pc projection (1024/600 or 10:6 has I've read on the net) ? Jan 16 '15 at 23:46

Alexey's answer is the most correct one.

\documentclass[aspectratio=169]{beamer}


To get this in emacs orgmode, make this line be your #+LaTeX_CLASS_OPTIONS

#+LaTeX_CLASS_OPTIONS: [aspectratio=169]


I added this to my earlier setting, smaller, like this:

#+LaTeX_CLASS_OPTIONS: [smaller,aspectratio=169]


As already mentioned, the size is fixed to a ratio of 4:3. However, you can decrease the right and left margin like this:

\documentclass{beamer}

\usepackage{beamerthemesplit}

\setbeamersize{text margin left=0.1em}  % <- like this
\setbeamersize{text margin right=0.1em} % <- like this

\title{The title of this presentation}
\author{Bart Kiers}
\date{\today}

\begin{document}

\frame{\titlepage}

\end{document}


which will make your slides look like:

EDIT:

And as neilfws mentioned, try the beamerposter package.

The following:

\documentclass{beamer}

\usepackage{beamerthemesplit}
\usepackage[orientation=landscape,size=custom,width=16,height=9,scale=0.5,debug]{beamerposter}

\title{The title of this presentation}
\author{Bart Kiers}
\date{\today}

\begin{document}

\frame{\titlepage}

\end{document}


produces:

According to A Beamer Quickstart, "The size of a Beamer slide is 128mm by 96mm. These dimensions are fixed and should not be changed."

However, there is a beamerposter package which allows a 16:9 ratio.

• Yes, that's better than my \setbeamersize{...} hack! +1
