Changes in left and right margins of the page

Question

to write my master's thesis, I'm using overleaf. I want the odd page numbers to be on the right where the even page numbers should be on the left side of the page. However, based on my measurements, it looks like the pages are somehow shifted in a way that the side with a page number has a bigger margin. I don't know what causes this. Thanks in advance.

Answer 1

Well, usually a master thesis would use class report or book instead of article (because you will need \chapter{} to give your thesis a structure) ...

Nevertheless see the following minimalised code:

\documentclass[a4paper,twoside]{article} % <============================ report??

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[%
  paperheight=11.0in,
% left=1.5in,right=1.0in,top=1.0in,bottom=1.5in,
  outer=1.5in,inner=1.0in,top=1.0in,bottom=1.5in, % <===================
  includefoot,heightrounded,
  showframe % <=========================================================
]{geometry}

\usepackage{blindtext} % <==============================================
\usepackage{xurl} % <=================================================== better url breaking
\usepackage[hidelinks]{hyperref} % <====================================

\begin{document}
\Blinddocument
\end{document}

To get a proper layout for twoside document you need to use options outer=1.5in,inner=1.0in, instead your used left and right.

Please see the following result:

Option showframe for geometry is only used to visualize the typing area and margins ... You can see the smaller inner margin and the bigger outer margin ... Please see the changed order of calls: hyperref should be called last in your case and xurl gives you a better line breaking in urls ...
