# Change the \frametitle font size; height also affected?

I want to change only the \frametitle font size. Changing this, is the height of the frame title going to decrease also? Because I want that.

I'm using the Warsaw theme.

Yes; changing the font size will also affect the height of the frametitle template. However, depending on the theme used the effect will be different; using Warsaw:

An image of the default frametitle height:

and with \tiny font size (as in the example code):

\documentclass{beamer}
\usetheme{Warsaw}
\setbeamerfont{frametitle}{size=\tiny}

\begin{document}

\begin{frame}
\frametitle{A test frame}
Test
\end{frame}

\end{document}


And using CambridgeUS:

\documentclass{beamer}
\usetheme{CambridgeUS}
\setbeamerfont{frametitle}{size=\tiny}

\begin{document}

\begin{frame}
\frametitle{A test frame}
Test
\end{frame}

\end{document}


An image of the default frametitle height:

and with \tiny font size (as in the example code):

The change can be locally applied to some specific frame(s), as the following example illustrates:

\documentclass{beamer}
\usetheme{Warsaw}

\begin{document}

\begin{frame}
\frametitle{A test frame}
Test
\end{frame}

{
\setbeamerfont{frametitle}{size=\tiny}
\begin{frame}
\frametitle{A test frame}
Test
\end{frame}
}

\begin{frame}
\frametitle{A test frame}
Test
\end{frame}

\end{document}

:Ok,thanks!And how can i apply it to only one slide? –  George Sep 25 '12 at 18:13
@George please see my updated answer (notice the use of braces to keep the change local). –  Gonzalo Medina Sep 25 '12 at 18:18
:Excellent,thanks! –  George Sep 25 '12 at 18:22
Isn't it the same (but easier) to just apply a desired font size command to a frame title's text? It seems to have the same effect. Am I missing something? –  Aleksandr Blekh Feb 27 at 9:01
@AleksandrBlekh but if the font change has to apply to all the frames, then you would have to apply the font switch to every \frametitle command. Setting the frametitle font as in, for example, \setbeamerfont{frametitle}{size=\tiny} will save you having to type \tiny for every title. –  Gonzalo Medina Feb 27 at 12:46
