To get a feeling for the sizes of the area reserved for text in different latex beamer layouts (themes) I am filling the text area with \blindtext. This works for simple frames with single column content. But when using multi column environments vertical text overflow appears. This happens for both, the columns and the minipage environments.
In addition to the question stated in the title, it would be great if someone knows a way to visualize the maximum space reserved for different contents like titles, text, headers, footers, etc. for different themes.
MWE:
\documentclass{beamer}
\usepackage{blindtext}
\usetheme{Frankfurt}
%#############################################################
\begin{document}
\begin{frame}
\blindtext
\end{frame}
% Two columns using minipage
\begin{frame}
\begin{minipage}{0.5\textwidth}
\blindtext
\end{minipage}%
\begin{minipage}{0.5\textwidth}
\blindtext
\end{minipage}
\end{frame}
% Two columns using columns
\begin{frame}
\begin{columns}[onlytextwidth]
\begin{column}{.5\textwidth}
\blindtext
\end{column}
\begin{column}{.5\textwidth}
\blindtext
\end{column}
\end{columns}
\end{frame}
\end{document}
The three output frames from the above MWE are shown below:
