Inserting space after the number in footnotes

Question

Text of Footnotes are very close to their numbers. How can I make 2mm space after all footnote numbers (or 2mm before every footnote text)?

\documentclass[draft,12pt,a4paper]{article}

\begin{document}
X\footnote{x}

Y\footnote{y}
\end{document}

Answer 1

I'm not sure if I correctly understood your question. I guess you are trying to adjust the distance between the number of the footnote and the footnote text (and not the regular text).

If you want to do so, try this:

\documentclass[draft,12pt,a4paper]{article}
\usepackage[hang]{footmisc}
\setlength{\footnotemargin}{2mm}
\begin{document}
X\footnote{x}

Y\footnote{y}
\end{document}

Normal spacing:

Increased spacing:

Answer 2

Here is on possible solution that redefines the \footnote command. I'm sure there is a more elegant solution using a package, but this works. The amount of space can be adjusted by changing the value inside of \hspace{}; it is currently using 2mm as specified.

Output: before: , after:.

Code:

\documentclass[draft,12pt,a4paper]{article}
% ADD THESE LINES TO YOUR PREAMBLE %
\let\oldfootnote\footnote
\renewcommand\footnote[1]{%
\oldfootnote{\hspace{2mm}#1}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
X\footnote{x}

Y\footnote{y}
\end{document}

Answer 3

This suggestion is based on this answer.

\documentclass[draft,12pt,a4paper]{article}
\makeatletter%
\long\def\@makefntext#1{%
  \parindent 1em\noindent \hb@xt@ 1.8em{\hss \@makefnmark}\hskip2mm\relax#1}%
\makeatother
\begin{document}
X\footnote{x}

Y\footnote{y}
\end{document}

Answer 4

I don't like the superscripted footnotemarks, so I use the following settings:

\documentclass{article}
\makeatletter
\newlength{\fnBreite}
\renewcommand{\@makefntext}[1]{%
  \settowidth{\fnBreite}{\footnotesize\@thefnmark.i}
  \protect\footnotesize\upshape%
  \setlength{\@tempdima}{\columnwidth}\addtolength{\@tempdima}{-\fnBreite}%
  \makebox[\fnBreite][l]{\@thefnmark.\phantom{}}%
  \parbox[t]{\@tempdima}{\everypar{\hspace*{1em}}\hspace*{-1em}\upshape#1}}
\makeatother

\begin{document}
This is a new\footnote{displays here} footnote
\end{document}
