# Change paper size in mid-document

My document should be letterpaper and my attachments should be a4paper. I had high hopes for the \newgeometry command from the geometry package, but the documentation says

\newgeometry is almost similar to \geometry except that \newgeometry disables all the options specified in the preamble and skips the papersize-related options: landscape, portrait and paper size options (such as papersize, paper=a4paper and so forth).

Any help is appreciated!

In case someone is looking for a similar solution for ConTeXt, the ConTeXt wiki shows how to change paper size mid document –  Aditya Jun 22 '11 at 21:18

The following works in PDFLaTeX:

\documentclass{article}
\begin{document}
Normal page
\eject \pdfpagewidth=3in \pdfpageheight=10in
Tall page
\eject \pdfpagewidth=10in \pdfpageheight=3in
Wide page
\end{document}


That should work with Xelatex. See the SO qn, Change paper size in the middle of a latex document?, for more.

When I use that, how can I reset everything to the page dimension of the document class for the next page? –  WarrenFaith Feb 18 '11 at 14:28
@Warren: These are normal dimension variables, so you can save the current values of the pages in the usual way using, say, \classpageheight=\pdfpageheight at the beginning and restore using \pdfpageheight=\classpageheight. –  Charles Stewart Feb 19 '11 at 21:33
I am a complete beginner, so I don't know the "usual way". Thanks for the information! –  WarrenFaith Feb 19 '11 at 22:56
@CharlesStewart : do you mean "\newlength{\classpageheight} \setlength{\classpageheight}{\pdfpageheight}" instead of "\pdfpageheight=\classpageheight"? (as I cannot get the stanza with the = to work)... Thanks! –  sdaau May 11 '12 at 10:08
@sdaau: Yes, you need to tell Tex that \classpageheight is a dimension using \newdim or \newlength, or as you have found, the assignment (using = or \setlength) won't work. –  Charles Stewart May 14 '12 at 18:45

You can use the typearea package (KOMAScript bundle) to change the paper size and also recalculate all dependent margins, header and footer positions etc. The following code demonstrates the technique but generates some warnings related to offended typesetting rules (placing 10pt font on A3 is not recommended). You might need to adjust some further typearea settings for better results.

\documentclass[a4paper]{article}
\usepackage[paper=A4,pagesize]{typearea}

\usepackage{lipsum}% dummy code
\begin{document}
\lipsum% Placed on A4

\clearpage
\KOMAoptions{paper=A3,pagesize}
\recalctypearea

\lipsum% Placed on A3

\clearpage
\KOMAoptions{paper=A4,pagesize}
\recalctypearea

\lipsum% Placed on A4 again

\end{document}

Here is an abridged example which switches between two custom page sizes with corresponding layouts (margins), which can compile with pdflatex - for more details, see my answer in Problem with setting correct custom page size with 'geometry' in xelatex:

\documentclass{article}

% reminder: US letter: 596pt x 795pt

\newlength{\pagewidthA}
\newlength{\pageheightA}
\setlength{\pagewidthA}{300bp}
\setlength{\pageheightA}{400bp}

\newlength{\pagewidthB}
\newlength{\pageheightB}
\setlength{\pagewidthB}{400bp}
\setlength{\pageheightB}{500bp}

% stockwidth and stockheight - from memoir,
% here just for cheating layouts warnings
\newlength{\stockwidth}
\newlength{\stockheight}

\usepackage{geometry}

% this command will take effect into L1 layout just after \begin{document}
% but the L1 geometry will otherwise be ignored
\geometry{twoside,inner=50bp,outer=30bp,top=50bp,bottom=50bp}

\usepackage{tikz,enumitem}
\usepackage{fix-cm}

\usepackage{layouts}
\usepackage{etoolbox}
\patchcmd{\drawpage}{\ifdrawparameters}{\iftrue}%
{\typeout{^^J*******\string\drawpage fixed*******^^J}}%
{\typeout{^^J*******\string\drawpage not fixed*******^^J}}

\usepackage{lipsum}

\makeatletter
\newcommand{\printpagevalues}{%
% from geometry.sty:
* paper: \ifx\Gm@paper\@undefined<default>\else\Gm@paper\fi \\%
* layout: \ifGm@layout<custom>\else<same size as paper>\fi \\%
\@ifundefined{ifGm@layout}{}{%
\ifGm@layout
* layout(width,height): (\the\Gm@layoutwidth,\the\Gm@layoutheight) \\%
\fi
* layoutoffset:(h,v)=(\the\Gm@layouthoffset,\the\Gm@layoutvoffset) \\%
}%
\pagevalues % from package layouts
}
\makeatother

\newcommand{\generatePageLayouts}{%
\newgeometry{layoutwidth=\pagewidthA,layoutheight=\pageheightA,left=1mm,right=5mm,bottom=1mm,top=1mm}
\savegeometry{LayoutPageA}

\newgeometry{layoutwidth=\pagewidthB,layoutheight=\pageheightB,twoside,inner=2.5cm,outer=0.5cm,top=1.5cm,bottom=1.5cm}
\savegeometry{LayoutPageB}
}

\newcommand{\switchToLayoutPageA}{%
% switch page size first:
\pdfpagewidth=\pagewidthA \pdfpageheight=\pageheightA % for PDF output
\paperwidth=\pagewidthA \paperheight=\pageheightA     % for TikZ
\stockwidth=\pagewidthA \stockheight=\pageheightA % hyperref (memoir)?!
}

\newcommand{\switchToLayoutPageB}{%
% switch page size first:
\pdfpagewidth=\pagewidthB \pdfpageheight=\pageheightB % for PDF output
\paperwidth=\pagewidthB \paperheight=\pageheightB     % for TikZ
\stockwidth=\pagewidthB \stockheight=\pageheightB % hyperref (memoir)?!
}

\begin{document}
% here geometry layout L1 is instantiated;
% without anything else, paper size defaults to US letter!
% \restoregeometry command restores L1!!

\fontsize{8}{9}\selectfont % this nowork in preamble!

% generate page layouts first based on layoutwidth as page size;
% don't switch actual page sizes yet:
\generatePageLayouts{}

\switchToLayoutPageA{}

\pagestyle{empty} % no page numbers here
\ \\

\the\paperwidth
\lipsum[1]
\printpagevalues{}
\clearpage

% switch to LayoutPageB (includes switching page size)
\switchToLayoutPageB{}

% start page numbering here ("this will reset the page number"):
\pagenumbering{arabic}
% make page numbers visible
\pagestyle{plain}

\the\paperwidth
\lipsum[1]
