Assume that I need a beamer frame with more text than fits on the frame. For a good readability, I don't like scaling elements which contain text, how can I instead automatically choose a suitable font size so the text fits in the frame? 

```
\documentclass{beamer}

\usepackage{lipsum}

\begin{document}

\begin{frame}
  \lipsum[1-5]
\end{frame}
\end{document}
```

One possibility is to use the `fitting` library from the `tcolorbox` package:

```
\documentclass{beamer}

\usepackage{lipsum}
\usepackage{tcolorbox}
\tcbuselibrary{fitting}

\begin{document}

\begin{frame}
 \begin{tcolorbox}[fit,width=\textwidth,height=.9\textheight,size=minimal,colback=white,fit algorithm=fontsize,colframe=white]
  \lipsum[1-5]
 \end{tcolorbox}
\end{frame}
\end{document}
```

(Dependingly on how tall other elements on the frame are, you might have to adjust `height=.9\textheight` to a suitable value)
