[Tex/LaTex] Space between footnote index and text

Question

I think there is not enough space in a footnote between the index (the superscript 1, 2, etc.) and the text (inside \footnote{...}). How can I increase the space between the index and the text?

Answer 1

This is the rough scaffold I use to make changes to the footnote format (replace the 1em by whatever suits you):

\documentclass{scrartcl}
\usepackage{blindtext}

\makeatletter
  \long\def\@makefntext#1{\leavevmode%
    \@thefnmark)\hspace{1em}\nobreak
    \relax#1%
  }
\makeatother

\begin{document}
\blindtext\footnote{\blindtext}
\end{document}
