# Figure on A3 page within A4 document

In my dissertation, I got some diagrams that don't fit a single (horizontal) A4 page. Hence I decided to print them on A3 pages that might be unfolded when reading. I followed the instructions in several posts, including this one:

Insert foldable A3 pages in an A4 document with active references

My first attempt looks like this:

\newpage
\begingroup
\pdfpagewidth=2\pdfpagewidth
\noindent%\makebox[0pt][l]{%
\begin{figure}
%graphics go here
\caption{foo}
\end{figure}
\newpage
\endgroup


When replacing the figure with plain text, I indeed get a A3 landscape page within my document. Unfortunately, this doesn't seem to work for the figure-environment, since neither the graphics, nor the caption are displayed.

Please note that I want to reference the figures, hence pdfpages might not be an option.

In general you can't put a figure, which is a float, into a box, e.g. \makebox[0pt][l]{..}. Instead apply the box command to the content if figure. Also, in this case you should use \clearpage not \newpage to create a new page but clear all pending floats (figures and tables) first. This way you insure that your figure is placed before the group ends. – Martin Scharrer Jan 19 '13 at 8:01
The hugepage environment in the answer to the above linked question didn't work for you? – Martin Scharrer Jan 19 '13 at 8:03
AFAIR is the geometry package able to create different geometries within one document. – Uwe Ziegenhagen Jan 19 '13 at 14:01
@UweZiegenhagen: Yes, but it doesn't allow you to change the paper size mid-document – Martin Scharrer Jan 19 '13 at 14:16
