As I specify in the title, I want to be able to include symbols like alpha and beta in my slides, in normal text format in both the body of the slide and the frame title.

Besides, I want these symbols bigger than the rest of the text...

I am not sure which packages I load in my real presentation, cause there I can see the alpha and beta symbols but I cannot alter their size. With the following MWE I cannot even see alpha and beta...

How can I accomplish this?

This is my MWE:

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{\huge{\alpha} and \huge{\beta} diversities}
    I want to study \huge{\alpha} and \huge{\beta} diversities, and I want \alpha\ and \beta\ to be bigger...
\end{frame}

\end{document}

Which produces this: fig

  • Have a look at textgreek and its command sequences. They should also work with beamer.

Your syntax of use \huge and Greek letters is wrong. Try this:

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{{\huge $\alpha$} and {\huge $\beta$} diversities}
    I want to study {\huge $\alpha$} and {\huge $\beta$} diversities, and I want $\alpha$ and $\beta$ to be bigger...
\end{frame}

\end{document}

  • So they can only be used in math mode?

  • {\huge \alpha} does not seem to affect the size...

  • as \alpha, \beta, ... yes, should be in math mode: $\alpha$, etc. for text mode see user124577 answer. so {\huge \alpha} is wrong, correct is {\huge$\alpha$}.

If you do not want to switch to the unicode characters and Xe/LuaLaTeX, then I recommend using textgreek and its \textalpha and so on.

greek

\documentclass{beamer}
\usepackage{textgreek}

\begin{document}

\begin{frame}
\frametitle{\huge{\textalpha} and \huge{\textbeta} diversities}
    I want to study \huge{\textalpha} and \huge{\textbeta} diversities, and I want \textalpha\ and \textbeta\ to be bigger...
\end{frame}

\end{document}

  • I get "Package textgreek Error: Cannot find the file lgrenc.def. ...GR. Maybe it comes with the babel package.}}"

    \huge is not an environment but command which switch all after it into huge size. correct use is {\hude <whatever>}.

  • @DaniCee Do you use babel? And if yes, which language do you include?
