Horizontal line spanning the page with asymmetric margins

Question

I wish to draw a horizontal line spanning the entire page. Previously I've been using the method in this answer, but I just found that it doesn't work properly on pages with asymmetric margins (say 2in on the left and 1in on the right, or vice versa).

I did come up with a method that works in all usual cases, but it is a little bit ugly:

\noindent\hspace*{-\paperwidth}\makebox[\linewidth]{\rule{4\paperwidth}{2pt}}

Do you have any suggestions?

Below is a MWE to play with.

\documentclass{article}
\usepackage[left=2in,right=1in]{geometry}
% \usepackage[left=1in,right=2in]{geometry}
% \usepackage[left=1in,right=1in]{geometry}
\begin{document}
\noindent\makebox[\linewidth]{\rule{\paperwidth}{2pt}}
% \noindent\hspace*{-\paperwidth}\makebox[\linewidth]{\rule{4\paperwidth}{2pt}}
\end{document}

have a look at the answer below --from --https://tex.stackexchange.com/questions/410689/i-need-to-draw-a-dotted-line-to-divide-a-page-ignoring-the-margin — js bibra, Mar 11 '21 at 09:05

This solution use TikZ. Remember to run it twice.

\documentclass[10pt,a4paper]{article}
\usepackage[left=2in, right=1in]{geometry}
\usepackage{lipsum}
\usepackage{tikz}
\begin{document}
\lipsum[1]
\begin{tikzpicture}[remember picture, overlay]
  \coordinate (baseline) at (0,{0.5\ht\strutbox-0.5\dp\strutbox});
  \draw (current page.west |- baseline) -- (current page.east |- baseline);
\end{tikzpicture}
\lipsum[1]
\end{document}

Thanks for this. May I ask what does {0.5\ht\strutbox-0.5\dp\strutbox} stand for? – Jinwen Mar 12 '21 at 05:03
That is the distance from the baseline to the center of a \strut. If you want the baseline, just use (0,0). – John Kormylo Mar 12 '21 at 14:22
I like this answer, since TikZ brings a lot features such as stylish dashed lines. It is a pity that it requires a second run to correctly locate the line. – Jinwen Mar 12 '21 at 14:29
[remember picture] stores the local origin in the aux file (which is the only way to get absolute locations). The second run is needed to read this value. – John Kormylo Mar 12 '21 at 14:49

\documentclass[10pt,a4paper]{article}
\usepackage[left=2in, right=1in]{geometry}
\usepackage{lipsum}
\begin{document}
\newcommand{\dividepage}{%
    \par\noindent
    \makebox[\linewidth]{\raisebox{.2\baselineskip}{\makebox[2\paperwidth]{\hrulefill}}}%
    \par
}

    \lipsum[1]

    \dividepage

    \lipsum[1]

\end{document}

Cool, how can I change the thickness of this \hrulefill? – Jinwen Mar 11 '21 at 09:08
i have no idea --you may like to ask a new question to attract a larger audience – js bibra Mar 11 '21 at 13:43
According to this answer, one may replace the \hrulefill by \leavevmode\leaders\hrule height ...\hfill\kern\z@ to allow changing its thickness. – Jinwen Mar 12 '21 at 05:05
