    \fontsize{10pt}{12pt}\selectfont

Answer 2

Example:

\Large\begin{verbatim}
   <how to set font size here to 10 px ? />
\end{verbatim}
\normalsize

\Large can be obviously substituted by one of:

\tiny
\scriptsize
\footnotesize
\small
\normalsize
\large
\Large
\LARGE
\huge
\Huge

If you need arbitrary font sizes:

Answer 3

The use of the package \usepackage{fancyvrb} allows the definition of the fontsize argument inside Verbatim:

\begin{Verbatim}[fontsize=\small]
print "Hello, World"
\end{Verbatim}

The fontsize that you can specify are the common

\tiny 
\scriptsize  
\footnotesize 
\small
\normalsize
\large
\Large
\LARGE
\huge
\Huge

To add exact fontsize you can use following. Worked for me since in my case predefined ranges (Large, tiny) are not match with the font size required to me.

\fontsize{10}{12}\selectfont This is the text you need to be in 10px

use \alltt environment instead. Then set size using the same commands as outside verbatim environment.
