Is there a way to change the vertical space before/after theorem environments, without defining a new theorem style? I'm using amsthm package to define my new theorem environments.

Without defining new theorem styles, you can modify the macro that's used by default, which is \thm@space@setup

  \thm@preskip=5cm plus 1cm minus 2cm
  \thm@postskip=\thm@preskip % or whatever, if you don't want them to be equal






The default value is \topsep. You don't need to have the same space above and below the theorem.

  • Ha! Perfect!! Thanks so much. Just one question: is \topsep used only by this macro? May I change only its value?

    @Sigur \topsep is the parameter normally used by list environments (enumerate, itemize and description); I would change neither the spacing around theorems nor \topsep, for what it's worth. :)

    @Sigur \topsep is a rubber length. It's default value in the standard classes is 8pt plus 2pt minus 4pt (at 10pt size) or 10pt plus 4pt minus 6pt (at 12pt size). I believe it's a good compromise: not larger than the baseline skip (at least in its natural length), but flexible enough. Theorems already have a header that, together with the spacing, makes them prominent enough.

    Is there a way to adjust the two parameters locally?

    Is there a way to modify the before/after environment spacing for a single instance?
