    In addition to Bernards comment, it also depends on which document class you're using. Some provide their own interface to change things like this.

  • What's the main document font size? 10pt, 11pt, 12pt, or something else? Is Times (new) Roman the main document font?

You can simply copy the definition from report.cls and change the font in \subsection to normalsize (12pt) italic, and use fontspec to put the document in Times New Roman.

You need lualatex or xelatex on Windows to access Times New Roman in this way (I used cygwin texlive here).

enter image description here


\setmainfont{Times New Roman}
                                     {-3.25ex\@plus -1ex \@minus -.2ex}%
                                     {1.5ex \@plus .2ex}%
%                                     {\normalfont\large\bfseries}}


\subsection{italic 12 pt subsection}
Some text.
