# [Tex/LaTex] Change in font size from slide to slide

beamerfontsize

Is it possible, that one of my slide in beamer is 11 pt and I want 10 pt font in other slide?

You can switch to a different font size outside the frame, and specify the scope using a group:

\documentclass[11pt]{beamer}
\let\Tiny\tiny% http://tex.stackexchange.com/q/58087/5764
\begin{document}

\begin{frame}
\frametitle{This is a title 11pt}
Here is some content on the slide
$f(x) = ax^2 + bx + c$
Some more content
\end{frame}

\begingroup
\small% \small in 11pt base font is 10pt
\begin{frame}
\frametitle{This is a title 10pt}
Here is some content on the slide
$f(x) = ax^2 + bx + c$
Some more content
\end{frame}
\endgroup

\begin{frame}
\frametitle{This is a title 11pt}
Here is some content on the slide
$f(x) = ax^2 + bx + c$
Some more content
\end{frame}

\end{document}


Above I've specified \small, which defaults to 10pt font under an 11pt document class option.

Since each of the frame components use template-specific settings, they need to be adjusted separately. However, the above technique is an easy one to update the internal frame content only.
