# How to fix: odd and even pages have different margin

I want that all the pages (odd und even) of my thesis document have the same geometry but the problem is that the odd and the even pages have different margin

Here is my configuration:

-------
\geometry{
paper=a4paper, % Change to letterpaper for US letter
%showframe, % Uncomment to show how the type block is set on the page
left=4cm,
right=2cm,
top=2.5cm,
bottom=2cm,
}


Can someone help me please how to fix this problem.

Use option asymmetric:

\documentclass{book}
\usepackage{blindtext}% only for dummy text
\usepackage{geometry}
\geometry{
paper=a4paper,
%showframe,
left=4cm,
right=2cm,
top=2.5cm,
bottom=2cm,
}
\begin{document}
\blinddocument
\end{document}


Result:

• this Problen can be fixed with \documentclass[ oneside, ] too – AhmyOhlin May 3 '18 at 19:09

This is what I obtain with your setting.

\documentclass{book}
\usepackage{geometry}
\geometry{
paper=a4paper,
left=4cm,
right=2cm,
top=2.5cm,
bottom=2cm,
}
\usepackage{lipsum}
\begin{document}
\lipsum[1-15]
\end{document}


I suggest you to provide a MCVE. Don't post your full thesis.
