# Headrule not centered over text, how to fix?

For some reason the headruler I added in my document isn't as long as the \textwidth. It doesn't seem to be centered but it could also be that it's asymetrical, and I don't know why?

See the picture and you will see my document in \showframe mode and the headruler not stretching as wide as the text box.

To the left the headruler code is also visible.

So, how to fix this?

PS; The following code example is similar and reproduces the headruler problem.

\documentclass[10pt,titlepage,twoside]{article}
\usepackage[a6paper]{geometry}
\usepackage[utf8]{inputenc}
\usepackage[swedish]{babel}
\sloppy
\usepackage{graphicx}

\usepackage{fancybox}
\usepackage{fancyhdr}
\pagestyle{fancy}

\usepackage[
cam,
width=11.1truecm,
height=15.4truecm,
center,
pdflatex,

\usepackage{showframe}
\evensidemargin = -10mm
\oddsidemargin = -11mm
\textheight = 124mm
\textwidth = 75mm
\marginparwidth = 0pt
\footskip = 5mm

\usepackage{fourier-orns}

• Your definition starts with a space (and has several other probably unintended spaces). Try adding a comment at the end of lines that don’t end with control words (lines 65, 67, and 73). Adding a complete example people can compile is helpful too. – TH. Dec 29 '18 at 17:28
• Please -- asusual here -- show us a complete compilable code resulting in your error we can copy and test on our own computers ... – Mensch Dec 29 '18 at 17:37
• @TH: Well seen! – user31729 Dec 29 '18 at 17:38
• Added some code :) ^^ It's a complex document so started with a screenshot. But yes, a code is a must in order to find problems. – Victor Ekekrantz Dec 29 '18 at 17:49
• @VictorEkekrantz: Are you really changing layout parameters and using geometry package together? ;-) – user31729 Dec 29 '18 at 17:54

Well, in your given code are some issues, for example you did not show us the used *.bib file, you did not add \title and \author and you used geometry and local settings ...

To solve your issue simple delete/comment the local setings:

%\evensidemargin = -10mm % <============================================
%\oddsidemargin = -11mm
%\textheight = 124mm
%\textwidth = 75mm
%\marginparwidth = 0pt
%\footskip = 5mm


Please read the documentation of package geometry (type texdoc geometry on your terminal/console) and add with package options the needed margins etc. to geometry. I leave this to you ...

With the following corrected code

\documentclass[10pt,titlepage,twoside]{article}
\usepackage[%
a6paper,
showframe % <=========================================================
]{geometry}
\usepackage[utf8]{inputenc}
\usepackage[swedish]{babel}
\sloppy
\usepackage{graphicx}

\usepackage{fancybox}
\usepackage{fancyhdr}
\pagestyle{fancy}

\usepackage[%
cam,
width=11.1truecm,
height=15.4truecm,
center,
pdflatex,
]{crop}

%\evensidemargin = -10mm % <============================================
%\oddsidemargin = -11mm
%\textheight = 124mm
%\textwidth = 75mm
%\marginparwidth = 0pt
%\footskip = 5mm

\usepackage{fourier-orns}
\hrulefill%
\raisebox{0pt}[10pt][10pt]{%

\decofourright%
\hrulefill}

you get the resulting pdf:

BTW: If you use \citep in your code you should call package natbib ... I also used option showframe of package geometry instead package showframe ...

• Wow, nice thanks very much appreciated :) ^^ The showframe in Geometry I found especially neat. I will accept your answer because it was very helpful and will sort out the problem for any future visitor to this thread. – Victor Ekekrantz Dec 29 '18 at 22:36
