Times New Roman with LaTeX (mathptmx)

Is it possible to change the look of \infty when using mathptmx? It looks horribly small compared to the other characters.

The following defines a \Infty from mathpazo

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{mathptmx}
\DeclareSymbolFont{Symbols}{OMS}{zplm}{m}{n}% Palatino
\DeclareMathSymbol{\Infty}{\mathord}{Symbols}{"31}
\begin{document}

\Huge$\infty$ $\Infty$

\end{document}

Since you're working with Times (New) Roman fonts, you could look into using either the mtpro2 package (the "lite" subset of this package is free of charge) or the newtxmath package. Both packages will give you lots of symbols, in addition to the infinity symbol, that look a lot better than what's provided by the mathptmx package.

First, just for reference, the look of the infinity symbol generated by the mathptmx package as well as the MWE's source code:

\documentclass{article}
\usepackage{mathptmx}
\begin{document}\Huge
$\infty$
\end{document}


Replacing \usepackage{mathptmx} with \usepackage{mtpro2}, one gets:

Finally, using \usepackage{newtxmath} instead, one gets:

Yes indeed! I posted this a long while ago and nowadays I would always recommend using mtpro2 instead of mathptmx –  hwhm Dec 19 '12 at 13:40
