[Tex/LaTex] page size and font size in latex beamer

beamerfontsizepdfpages

I need to add page size as Letter Paper: 8-1/2X11 and font size 24 pt but the following code does not worked. What is a solution for these two changes?

\documentclass[24pt]{beamer}

You can use the beamerposter package to set a custom page size:

\documentclass{beamer}
\usepackage[orientation=portrait,size=custom,width=21.59,height=27.94]{beamerposter}
\setbeamertemplate{navigation symbols}{}

\begin{document}

\begin{frame}[t]{slide title}
this is written in 24 point font.
\end{frame}

\end{document}

Notice that the height and width are in cm-- beamerposter seems to require that. And the line \setbeamertemplate{navigation symbols}{} removes the navigation symbols from the bottom of the page. You can remove that line if you want to keep them.
