# Change font size inside only one line of document

My article is written using 11 pt font, but I would like to write a line in bold using a size which is bigger than 11.

Here is the MWE:

\documentclass{article}
%
\begin{document}
\par
~
\par
\noindent
% I want to enlarge only this statement
\textbf{Analisi fluidodinamica su Stramazzo Generico}
% this is the text
Si immagini che un fluido perfetto e incomprimibile...
%
\end{document}

• is the line simply part of regular text, or do you know its start and end ahead of time? if it's already on a line by itself, you could use {\large\bfseries ...} to do the job. – barbara beeton Aug 6 '15 at 17:46
• I'm thinking you'll need the soul package here??? – 1010011010 Aug 6 '15 at 19:27
• I have just reported some code in the question – Cybex Aug 6 '15 at 20:07
• It's not really clear why the part should be in a larger font. Are you perhaps trying to emulate \subsection or something similar? – egreg Aug 6 '15 at 20:12
• @Cybex \subsection* – egreg Aug 6 '15 at 20:44

If you want to emulate \subsection, but without a number, just do

\subsection*{Analisi fluidodinamica su Stramazzo Generico}


If you just have numbered sections, but not subsections, add

\setcounter{secnumdepth}{1}


\subsection{Analisi fluidodinamica su Stramazzo Generico}

with the advantage that the subsections can go directly to the table of contents (provided tocdepth is set to 2 or more).
