# Extending the line drawn above footnotes

By default the line drawn where the footer begins is small in size. How can I make it bigger and make it match with the document text area size?

At first you should clarify by a minimal example how you get that line and where the problems are. Regardless of that, you should consult the manual of the package you use for your footer (and header). It will certainly be helpful. –  Thorsten Donig Oct 10 '11 at 9:08
Greetings! I've taken the liberty of adjusting the header of your question to better reflect the question's content -- it's about footnotes and footnote rules, not about footers. I've also changed the tag. –  Mico Oct 10 '11 at 11:17
Yes @Mico. It was my mistake –  nixnotwin Oct 10 '11 at 13:53

You can modify the \footnoterule command:

\documentclass{book}
\usepackage{lipsum}
\makeatletter
\renewcommand\footnoterule{%
\kern-3\p@
\hrule\@width \textwidth
\kern2.6\p@}
\makeatother
\begin{document}

Test \footnote{test} \lipsum*[1]

\end{document}

With a KOMA-Script class, you may use the \setfootnoterule[<height>]{<length>} macro.

\documentclass{scrartcl}

\setfootnoterule[2pt]{\textwidth}% default height is 0.4pt

\begin{document}

Some text\footnote{A footnote.}.

\end{document}
