# Decreasing font size increases border width

(hopefully) no duplicate of Number of pages decreases when font size increases, because the font size is one of the defaults.

In an attempt to fit more text on a page, I decreased the font size, only to notice that the border size increases.

\documentclass[11pt]{scrartcl}
\begin{document}
\begin{center}
\end{center}
Text
\end{document}


With [11pt], the output is as follows:

With [10pt], the text is of course smaller, but the border is considerably larger:

Does anyone know how this can be prevented, and why it occurs in the first place?

You can set the division factor (DIV) to 10 (the default value) to reset the margins (11pt above):

\documentclass[10pt,DIV=10]{scrartcl}
\begin{document}
\begin{center}
