# Different margin sizes on odd and even pages

I am polishing my thesis document. It is based on a custom style derived from report and it is supposed to deliver different sizes of margins on odd and even pages, however it doesn't work. In the .cls class someone attempted to fix this issue:

\setlength{\oddsidemargin}{0.5in}  % really 1.5in
\setlength{\evensidemargin}{0.5in}  % really 1.5in


but it doesn't seem to work at all, i.e. when I change the values the document looks the same.The class file is available here. How can I make it work?

• You may need to pass the twopage option to report: \documentclass[twopage]{report}. You should still provide a MWE to use with the provided class file, though. – Sean Allred Jun 15 '14 at 19:22
• or in this case, \documentclass[a4paper,plainchapterheads,yschapters,twoside]{ICMathsThesis} – srao Jun 15 '14 at 19:43
• @SeanAllred, it doesn't work sadly. Latex warns that twopage option is not recognised. – Grzenio Jun 17 '14 at 19:07
• @srao, unfortunately this doesn't have any effect. I found a comment in the class file: if we use the twoside option, we break the spacing rules, but it doesn't say how to get it to work... – Grzenio Jun 17 '14 at 19:08
• As an aside, if they knew how to get it to work, they would have implemented it. It would really help if you posted a minimal document using this class so we can help you. – Sean Allred Jun 17 '14 at 19:09

Using the twoside option seems to work fine for me, unless I am missing something. Here's a MWE:

\documentclass[a4paper,plainchapterheads,yschapters,twoside, truedoublelespace]{ICMathsThesis}
\usepackage{lipsum}

\title{High Accuracy Methods for the Solution to Two Point Boundary Value
Problems}
\author{Steven David Capper}
\department{Mathematics}

\begin{document}
\maketitle

\lipsum
\end{document}


Note that I am using the following settings in the .cls file for illustration purpose.

\setlength{\oddsidemargin}{0.9in}  % odd page left margin = 1 inch + \oddsidemargin ==> http://en.wikibooks.org/wiki/LaTeX/Page_Layout#Page_dimensions ; this can be negative
\setlength{\evensidemargin}{0.5in}  % even page left margin = 1 inch + \evensidemargin ; this can be negative
\setlength{\textwidth}{5.0in}


With truedoublespace option:

With singlespace option:

• Is there any scientific way to make it symmetric, i.e. the left margin on the odd pages should be the same as the right margin on even pages? – Grzenio Jun 18 '14 at 19:33
• It should be easy to calculate :) My understanding is that pagewidth = textwidth + [(\oddsidemargin or \evensidemargin) + 1 inch] + right margin – srao Jun 18 '14 at 20:31
• So how can I check what are pagewidth, textwidth or right margin` in this particular case? – Grzenio Jun 19 '14 at 10:24
• Pagewidth is the width of the page (a4paper in this case), textwidth is set in the .cls file as shown above. Right margin can then be easily calculated from these values. – srao Jun 19 '14 at 11:56
