I am doing one-page documents with title and I need more space so all text can be put on that page. I achieve this by \typearea{12}. What happens is that the footer margin gets absurdly large (say, 3 times side margins!). I've tried to fix that using \usepackage[bottom=10em]{geometry}, however this command effects all margins and there is no gain.
Is there any way just to make the footer margin thinner?
\documentclass[10pt]{scrartcl}
\typearea{12}
\renewcommand*{\titlepagestyle}{empty}
\begin{document}
\title{Title}
\author{Author}
\date{Date}
\maketitle
A lot of text.
\end{document}
