Text Formatting ⇒ Indent Footnote Text from Footnote Mark

[jpehs]

How can I indent the text of a footnote from the footnote mark rather than from the left page margin? I'm currently using this code to format my footnotes:

Code: Select all

\usepackage[hang,norule,ragged]{footmisc}
	\addtolength{\footskip}{0.5cm}
	\setlength{\footnotemargin}{3.5mm}
	\setlength{\footnotesep}{0cm}
	\makeatletter
	\let\splitfootnoterule=\pagefootnoterule
	\makeatother

The 3.5mm \footnotemargin setting is fine for notes up to no. 99, but the footnote text starts to be quite close to the footnote mark from no. 100 onwards. The press printing my book actually requires an em space between the footnote marker and the footnote text (with the text hanging to the same margin: footnote marker plus em space).
