# from A4 paper to A5 and keeping the number of characters per line

I have written my thesis for A4 paper using the memoir class. I would like to print one version on A5 paper. Is there a way to reduce margins automatically in order to keep the same layout for the text?

I mean, I have for instance 70 characters per line, I would like to keep this number of characters per line by decreasing the size of the margin.

edit: here is a picture of what I want to do (copy/paste in gimp):

original A4 paper

A5 paper (of course I want larger vecrtical margin, but the horizontal margins are perfect).

• What about reducing font size? – Astrinus Dec 10 '14 at 11:04
• Why don't you use pdfpages and \includepdf? – user11232 Dec 10 '14 at 11:16
• Unless you used unusual large margins the textwidth in the A4 paper is larger than a A5 paper, so it can't work without changing the font size. – Ulrike Fischer Dec 10 '14 at 11:37
• Sorry I was not clear enough. I would like to keep the same font size and picture size (or something close at least). I used the standard margins of memoir class that are quite large for A4. So I would like to decrease as much margins as possible. It does not matter if I have more pages at the end. I just want to keep something easy to read. note that I will print an official version in A4, the A5 version is for me. – nbi Dec 10 '14 at 12:19
• Perhaps with very minimalistic margins and A5 landscape format. – Bernard Dec 10 '14 at 13:31

With geometry

# a5paper

\documentclass[12pt]{article}
\usepackage{kantlipsum}
\usepackage[a5paper,textwidth=5in,textheight=7in]{geometry}
\begin{document}
\kant[1-40]
\end{document}


# a4paper

\documentclass[12pt]{article}
\usepackage{kantlipsum}
\usepackage[a4paper,textwidth=5in,textheight=7in]{geometry}
\begin{document}
\kant[1-40]
\end{document}


I have just fixed the textwidth to be same for both versions. Adjust the textwidth and textheight as suitable to you and keep them same for both papers.

• Thanks a lot, it is exactly what I want to do. It works, I just have to make few arrangement with my chapter style. – nbi Dec 10 '14 at 12:48
