# How do I use Times/Times Roman/Times New Roman in LaTex?

Ive been using LaTeX for a few days and have written up my entire document but am unable to change the font to any variant of Times/Times Roman/Times New Roman. I swapped from MS word on the recommendation of a friend and am absolutely loving it, especially the BibTex aspect. I am on a Mac using TeXShop.

I have tried using

\usepackage{times}
\usepackage{mathptmx}


but neither changes the font.

My preamble consists of

\documentclass[12pt]{article}
\usepackage{geometry}
\geometry{
a4paper,
total={210mm,297mm},
left=25mm,
right=25mm,
top=25mm,
bottom=25mm,
}
\usepackage[parfill]{parskip}
\usepackage{graphicx}
\usepackage{amssymb}
\renewcommand{\rmdefault}{ptm}
\usepackage{caption}
\usepackage{setspace}
\setlength{\parskip}{0.4cm plus4mm minus3mm}
\usepackage{apalike}
\usepackage{longtable}
\usepackage{fixltx2e}
\usepackage{graphicx}
\usepackage{textcomp}
\usepackage{float}
\usepackage{tikz}
\renewcommand{\familydefault}{\sfdefault}
\newcommand{\Mypm}{\mathbin{\tikz [x=1.4ex,y=1.4ex,line width=.1ex] \draw (0.0,0) -- (1.0,0) (0.5,0.08) -- (0.5,0.92) (0.0,0.5) -- (1.0,0.5);}}%
\title{Influence}
\author{}
\date{}                         % Activate to display a given date or no date
\begin{document}
\maketitle
\onehalfspacing

• you made times the default roman font but then \renewcommand{\familydefault}{\sfdefault} makes the document sans serif, just delete that line – David Carlisle Apr 26 '15 at 14:34
• Using LaTeX before TL2015 fixltx2e should be loaded as first Package even before the documentclass with \RequirePackage{fixltx2e}, see texdev.net/2014/12/28/fixing-latex2e – MaxNoe Apr 26 '15 at 14:37
• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. – Symbol 1 Apr 26 '15 at 14:46
• It is a good idea not to copy some preamble commands unless you know what they do. – Ludenticus Apr 26 '15 at 16:05

• Get rid of the instruction

\renewcommand{\familydefault}{\sfdefault}


Times Roman is a font with serifs. What good is supposed to come from selecting a sans-serif font as the main text font?

• Replace the instruction

\renewcommand{\rmdefault}{ptm}


with

\usepackage{newtxtext,newtxmath}

• A4 paper is, I believe, 210mm wide and 297mm tall. Thus, the second argument of the \geometry directive -- total={210mm,297mm} -- is redundant.
• Still on the \geometry directive: If all four margins are supposed to be equal to 25mm, it suffices to provide the option margin=25mm.
• No point loading the graphicx package twice, is there?
