How do I make my document use the Times font, both for the text and the math?

Question

I know that I can put \usepackage{times} in the preamble in order to use the Times font instead of Computer Modern for my document. But this only affects the text; the math is still typeset using Computer Modern. How can I make Latex use Times also for the math?

Answer 1

Probably the most common solution at present using free fonts is mathptmx

\usepackage{mathptmx}

This package supersedes times and mathptm.

The commercial mathtime is available in a 'lite' version in a free (cost) package, but you need to pay for the full version. See http://www.pctex.com/mtpro2.html

As noted in the answer by mafp, the newer newtx bundle is now available and addresses issues present in mathptmx.

Answer 2

If you don't mind using a Times-like font, a different engine, and the not yet officially released TeXLive-2010, then you can try XITS font with LuaLaTeX (my preference) or XeLaTeX:

\documentclass{article}

\usepackage{fontspec}
\usepackage{unicode-math}

\setmainfont{XITS} % you can use any other Times font if you wish
\setmathfont{XITS Math}

\begin{document}
Some text and \(\sqrt{x+y}=z\) equation
\end{document}

Answer 3

In the mean time, two new option for Times have emerges. The newtx package provides both text and math versions for Times via

\usepackage{newtxtext,newtxmath}

The TeX Gyre project supplies TeX Gyre Termes for text to be used with

\usepackage{tgtermes}

and a math version TeX Gyre Termes Math that currently only comes in Open Type Format, and can be used with

\usepackage{unicode-math}
\setmathfont[math-style=ISO,bold-style=ISO,vargreek-shape=TeX]{TG Termes Math}

in LuaTeX or XeTeX, and with

\starttypescript [math][times,termes][all]
    \definefontsynonym[MathRoman][file:texgyretermes-math-1010.otf][features=math\mathsizesuffix]
\stoptypescript

in ConTeXt.

Answer 4

With current TeXLive 2012 and lualatex or xelatex

\documentclass{article}    
\usepackage{unicode-math}
\setmainfont{TeX Gyre Termes}
\setmathfont{TeX Gyre Termes Math}

\begin{document}
Some text and \(\sqrt{x+y}=z\) equation
\end{document}

see package documentation of fontspec for optional arguments to the font setting.

Answer 5

I’ve been using the txfontsb package for Times, though generally I avoid Times. (After reading countless student papers in Times, it grates on me.)

Answer 6

Put

\usepackage[bigsym]{mathptm}

in your preamble. This makes LaTeX use the Times and Symbol fonts for math, except for large symbols (summation, integration, etc.) which look funny in the Postscript Symbol font.
