# move margin of pages for bookbinding

 \documentclass[a4paper,12pt,openright,twoside]{book}
\usepackage[utf8]{inputenc}
\usepackage{indentfirst}

\usepackage{fancyhdr}
\usepackage{booktabs}

\renewcommand{\chaptermark}[1]{\markboth{\thechapter.\ #1}{}}
\renewcommand{\sectionmark}[1]{\markright{\thesection \ #1}{}}

\begin{document}


I'd like to move the left margin for odd pages a bit more to the right, vice versa for even pages, right margin moved a bit more the left. I need more space in the sides of the bookbinding, with this configuration is centered so the binding takes space and the result is visually asymmetrical and difficult to browse. How should I do?

• Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – user31729 Jul 2 '14 at 9:38
• Use the geometry package. In my experience it is by far the easiest way to precisely control all of the page dimensions, including margins. – Andrew Jul 2 '14 at 9:44
• Either the geometry package, as Andrew already wrote or the usage of scrbook instead of book which takes care of the binding correction – user31729 Jul 2 '14 at 9:47

The lengths \oddsidemargin and \evensidemargin need to be augmented/decremented.
