I'm trying to make a document suitable for printing as a trade paperback. For that reason I'm using the memoir class using statementpaper which sets the page size to 5.5" x 8.5".
Here's the basic structure I have:
\documentclass[12pt,statementpaper]{memoir}
\usepackage{lipsum} % for sample text
\begin{document}
\lipsum
\end{document}
which produces the following pages:

As you can see, the margins are huge.
How can I get margin sizes that are more appropriate for paperback books of this size?
