# Change \textwidth and \textheight in mid-document

I set my \textwidth and \textheight in the preamble and would like to change both for some pages. How can this be done? E.g., the following example for \textwidth appears to work for the page number, but not for the text:

\documentclass{article}
\textwidth=5cm \textheight=5cm
\begin{document}
A \hfill B
\eject \textwidth=10cm
A \hfill B
\end{document}


Output (true to scale):

You can use \newgeometry and \restoregeometry from the geometry package:

\documentclass{article}
\usepackage[textwidth=5cm,textheight=5cm]{geometry}
\usepackage{lipsum}
\begin{document}

\lipsum[1-2]
\newgeometry{textwidth=10cm,textheight=10cm}
\lipsum[1-4]
\restoregeometry
\lipsum[1-2]

\end{document}

That's great - thanks. I had given up on the geometry package after it frustrated me in this question: tex.stackexchange.com/questions/6834/… –  Frank Seifert Mar 14 '11 at 22:11
