# beamerpost fontsize

I am using beamerpost for my poster. I found out how I manage to change the font size of my body. Is it possible to change the font size of title, subtitle, etc. independently as well? if yes, how?

Assuming you mean beamerposter with beamerpost, you can use \setbeamerfont for the individual fonts:

\documentclass{beamer}

\usepackage{beamerposter}

\title{text}
\subtitle{subtitle}

\setbeamerfont{title}{size=\fontsize{86pt}{92pt}\selectfont}
\setbeamerfont{subtitle}{size=\fontsize{72pt}{76pt}\selectfont}

\begin{document}
\begin{frame}
\maketitle
\end{frame}
\end{document}
