I have used nomencl package to create my papers nomenclature. The problem, however, is that the font size is 12pt, which is very large and takes many pages for nomenclature.

How can I decrease the font size to 10pt in nomencl package? I couldn't find anything about this.


Use the nomencl package features. The macro \nompreamble is used at the start of the list (after having produced the title) and you can redefine it as you wish. By default it does nothing.

Here I used \scriptsize to show the effect, use \small or \footnotesize instead.

I reused some code I already had, with some more customizations which you're free to keep or discard.

% arara: pdflatex
% arara: nomencl
% arara: pdflatex


\renewcommand{\nomname}{List of Symbols} %% may be this is good.
\renewcommand{\nompreamble}{\scriptsize} % just by way of example, use \small instead


% use this if you plan to have a nomenclature taking more than one page




\mainmatter % book mode only

  • Thank you for providing an MWE that includes nomenclatures. For my own interest I modified it to use my proposal. It seems that both of our answers work. Feb 29 '20 at 19:23

As far as I can tell nomencl does not set any font size, just uses the size set for the main document. I suspect you are using something like \documentclass[12pt,...]{...}. It would have been most helpful if you had provided an MWE and I'm not prepared to try and create one. --- GOM

Try something along these lines:

% lots of stuff
\begin{small}  % set font to small size
\end{small}    % end of small sized fonts
% more stuff?
