General ⇒ margin sizes

[dimarcom]

Hi again,

Below is the preamble of my document, with a few of the options i tried to change the margins (one is new since my last post: margin={.1\paperwidth}, i joined a new image).

I'm happy with header, footer, textheight, all vertical stuff.

I'm unhappy with the margins: i'd like to make the textwidth 0.5 or 1cm larger than default, but whatever i try does not respect the assymetry of a twoside book.

Hope you can help...
Marie.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass[12pt]{scrbook}
\usepackage[a4paper,twoside,margin={.1\paperwidth}]{geometry}
\textheight 23.5cm
\textwidth 16cm
%\oddsidemargin -0.5cm
%\evensidemargin -1cm

The command suggested by gmedina:

\usepackage[lmargin=2cm,rmargin=2.5cm,tmargin=3cm,bmargin=2cm]{geometry}

actually did exactly what i needed. It didn't work before because i had other conflicting commands, like \textheight 3.5cm for example.

i thought i'd mention it.

thanks for all the help, it's super useful !
