Horizontal line spanning the entire document in LaTeX

Question

I have used the \hrulefill command to create a horizontal rule, along with some other commands. In each case I have the rules extended up to the margin.

I want the rule width to be controllable, i.e. I want them to span the entire page. How can this be done? The existing help on Internet looks pretty scarce. Thanks for your help.

Answer 1

To get horizontal lines of any fixed length you can use the \rule command. To get a horizontal line spanning the whole page width you can use a \makebox command and then a \rule with a width equal to \paperwidth:

\documentclass{article}

\begin{document}

Below is a Line spanning the entire width of the page

\noindent\makebox[\linewidth]{\rule{\paperwidth}{0.4pt}}

Below is a 2cm long line

\noindent\rule{2cm}{0.4pt}

Below is a 4cm long line

\noindent\rule{4cm}{0.4pt}

Below is a 8cm long line

\noindent\rule{8cm}{0.4pt}

\end{document}

Output: Rules in LaTeX are 0.4pt "thick", by default.

Answer 2

Another option is this one, which makes a horizontal line stretch the entire page. I prefer this one, because it's short, easy to remember and exactly what I need. I hope this works for you too.

\noindent\rule{\textwidth}{1pt}

Answer 3

I used the \line command: \line(x slope, y slope){length}.

\begin{center}
\line(1,0){450}
\end{center}

Answer 4

\underline{\hspace{ x in}} gives you a line of length x inches.

Answer 5

Attending the horizontal line problem I used the \rule as other has mentioned. Although, if you want to have a centered line that separates your paragraphs you can use this simple code. You can add another \bigskip in order to add empty spacing :)

    \documentclass{article}
    \begin{document}
    
    Some random text above \\
    
    \centerline{\rule{13cm}{0.4pt}}
    \bigskip
    
    Some random text below 
    
    \end{document}
