Is there supposed to be a space before a footnote reference mark? For example:

This is a sentence. 1

(let's say 1 is the footnote number) or there isn't supposed to be a space, so,

This is a sentence.1

Which is the preferred way?

  • There is no universal standard; such concerns are largely a matter of style. Adhere to the discipline of your editor, publication, or organization, or in the absence of a house style, choose a style manual appropriate to your audience and tastes and be consistent in its application.

  • What is a footnote reference mark?? Do you just mean a footnote number? Footnotes are generally numbered.

It depends on your referencing methods - APA, MLA, Oxford, Harvard, Chicago, etc.

Personally, I would omit the space.1


Purdue OWL is a good place to find information - and they, as well as Wikipedia, don't have spaces.

1 To get Superscript, use html formatting like the following <sup>1</sup>

    But what do the reference methods suggest?

    For a superscript 1, use Unicode 00B9 (185): ¹

    I have never seen a style guide that suggests leaving a space before a footnote marker. (There may be some, but in 30 years of editing I haven't come across one...) Mar 17 '18 at 19:13
