Thanks, I have done that now.

What I have in the file is:

\documentclass[10pt,a4paper]{article}
...
\newsavebox{\logobox}
\sbox{\logobox}{...} % as previously defined
%
\newlength{\pheight}
\newlength{\pwidth}
\settoheight{\pheight}{\logobox}
\settowidth{\pwidth}{\logobox}
%
\usepackage[paperwidth=\pwidth,paperheight=\pheight]{geometry}
\begin{document}
%
\usebox{\logobox}
%
\end{document}

This gives me four small empty pages instead of one correctly sized small page 
tightly fitted to the logo.

Can you please tell me what I am doing wrong?

Thanks.
