[Tex/LaTex] How to add binding space to memoir twoside

double-sidedmarginsmemoir

I'm using the LED template to MSc which uses memoir twoside.
I need to print it and it requires extra margins for binding.

How do I simply add the extra space on the spine side of the page?

\documentclass[11pt, a4paper, twoside, makeidx]{memoir}
\input{style.tex}

STYLE.TEX:

\usepackage{graphicx}
\usepackage{epsfig}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{amsthm}
\usepackage{booktabs}
\usepackage{stmaryrd}
\usepackage{url}
\usepackage{longtable}
\usepackage[figuresright]{rotating}
\usepackage{geometry}

\usepackage{polski}
\usepackage[cp1250]{inputenc}

Best Answer

As described in the memoir manual, chapter 2, the command \setlrmargins is available to adjust margins, with arguments:

\setlrmargins{<spine>}{<edge>}{<ratio>}

Only one argument could be given, with * for the two others e.g.

\setlrmargins{*}{2cm}{*}

There is also a command

\setbinding{<length>}

that adds to the inner margin to allow for the binding. This should be added after setting the page size, but before setting the margins.
