How to modify side margins in front pages (declared in subenvironment)?

Question

I'm about to submit my thesis and I just noticed the first pages have different sidemargins to the rest of the text :(. They are supposed to be 2.5cm and they apper of ~ 1in.

I tracked the problem to the different environments I declare for each of these pages but can't figure out how to change them back [I have looked around before asking but haven't find the solution], here's a brief example of one of the environments:

\newenvironment{myenvironment} {\thispagestyle{plain}
  \begin{center}
  \vspace{0cm}
  {\Large \bfseries TITLE}
  \end{center}
  \vspace{0.5cm}
   \begin{quote}}
{\end{quote}}

For some reason the above code overrides the margin settings of the rest of the document. I have tried to declare them inside the environment using \setlength and also the geometry package (\newgeometry{top=X, bottom=Y}) to no avail.

This is my first big LaTeX project so I'm probably missing something here. Thanks!

Answer 1

First of all, 2.5cm is about 0.98 inches, so you're drawing a thin line here. Second, your code includes \begin{quote} ... \end{quote} which sets additional margins.

You can substitute \begin{quote} by \list{}{\rightmargin=0pt \leftmargin=0pt} \item\relax and \end{quote} by \endlist. (not tested).

Answer 2

Yous can use geometry package.

\usepackage[a4paper,bindingoffset=0.2in,left=2.5cm,right=2.5cm,top=2.5cm,bottom=2.5cm]{geometry}

You can simply say [margin=2.5cm] to have all margins as 2.5cm. Change tha paper as you wish. In the middle if you want to change the lay out, you can use

\newgeometry{left=0.8in,right=0.8in,top=1in,bottom=1in}

and after some pages if you want old layout back, just say

\restoregeometry

For details run texdoc geometry from command prompt.
