[Tex/LaTex] How to set document font to times new roman by command

chaptersfontsfontsizeformatting

I wanted to know how to set font of a document to Times New Roman and size to 12 for text and for Chapter Heading 14 only, for the whole document. I don't want to use the fontspec package for this. Please help me out on this.

Let's construct what you're after:

  1. 12 point text font

    For this you can pass a 12pt option to the document class. For example, use

    \documentclass[12pt]{book}

  2. Times New Roman font

    While there is no actual Times New Roman font in native LaTeX, the closest you'll get is by adding the mathptmx package

    \usepackage{mathptmx}

    or the newtx bundle

    \usepackage{newtxtext,newtxmath}

    to your document preamble. To check the actual font is included when doing this, see How do I find out what fonts are used in a document/picture?.

  3. 14 point chapter heading

    Under the 12pt document class option, the closest to 14pt is provided by the \large switch (see What point (pt) font size are \Large etc.?) - it'll actually be 14.4pt, but that would be what the font has to offer. However, the current \chapter heading is set (by default) in a combination of \huge and \Huge (the former for the chapter heading - Chapter X, and the latter for the chapter title A chapter). So, we can patch the appropriate macro(s) (\@makechapterhead and \@makechaptershead) and substitute \large for \huge (with the aid of etoolbox):

    \usepackage{etoolbox}

\makeatletter
% \patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}
\patchcmd{\@makechapterhead}{\huge}{\large}{}{}% for \chapter
\patchcmd{\@makechapterhead}{\Huge}{\large}{}{}% for \chapter
\patchcmd{\@makeschapterhead}{\Huge}{\large}{}{}% for \chapter*
\makeatother

Here's a MWE that contains the above suggestions:

enter image description here

\documentclass[12pt]{book}

\usepackage{lipsum,mathptmx,etoolbox} % Or swap mathptmx with newtxtext,newtxmath

\makeatletter
% \patchcmd{<cmd>}{<search>}{<replace>}{<success>}{<failure>}
\patchcmd{\@makechapterhead}{\huge}{\large}{}{}% for \chapter
\patchcmd{\@makechapterhead}{\Huge}{\large}{}{}% for \chapter
\patchcmd{\@makeschapterhead}{\Huge}{\large}{}{}% for \chapter*
\makeatother

\begin{document}

\chapter{A chapter}
\lipsum[1]

\section{A section}
\lipsum[2]

\end{document}

Note how the \section title is now larger (set using \normalfont\Large\bfseries) than the \chapter title - a definite problem. However, you requested Chapter Heading 14 only.
