I have a week to submit my Ph.D thesis, done in latex, and have ran into a strange difficulty. Before introducing {\usepackage[rm,tiny,compact, bf]{titlesec} } which was necessary in order to unify all titles in the entire thesis to document size as per university requirements, my chapters headings read CHAPTER ONE (etc). this was accomplished using


Now they read CHAPTER 1 (etc), which is unacceptable! So how can I retain the CHAPTER ONE (etc) format and still use titlesec? Urgent response will be highly appreciated, for obvious reasons.

    Would you please provide a mock-up of your document in the form of a minimal working example (MWE) so we can replicate problem? Help us help you... Obviously titlesec doesn't use \@makechapterhead to set its titles...

  • You shall have to use the advanced interface of titlesec, at least for chapters, somrthing like \titleformat{\chapter}[display]{\bfseries}{\chaptername \Numberstring{chapter}}{…}{…}.

  • Thanks Werner. This preamble produced CHAPTER ONE in my thesis: Commented Jul 18, 2015 at 17:57
  • \documentclass[12pt,a4paper]{report} \renewcommand{\contentsname}{\bfseries\footnotesize\center TABLE OF CONTENTS} \usepackage{fancyhdr} \renewcommand{\chaptername}{\center \small CHAPTER} \newcommand{\cchapter}[1]{\chapter[#1]{\centering #1}} \usepackage{fmtcount,etoolbox} \makeatletter \patchcmd{\@makechapterhead}{\thechapter}{\Numberstring{chapter}}{}{} \patchcmd{\chaptermark}{\thechapter}{\NUMBERstring{chapter}}{}{} \makeatother \usepackage[rm,tiny,compact, bf]{titlesec} Commented Jul 18, 2015 at 18:11
  • It produced the CHAPTER ONE format, until I introduced the \usepackage[rm,tiny,compact, bf]{titlesec} line of code. This reverted it to CHAPTER 1. Commented Jul 18, 2015 at 18:13

This code hopefully results in something close to what you want. I replaced loading fancyhdr with titleps, a sibling of titlesec which eases (re-)defining page styles :

\documentclass[12pt,a4paper, openright, twoside]{report}

\renewcommand{\contentsname}{TABLE OF CONTENTS}

\usepackage[pagestyles, clearempty]{titlesec}%

\sethead[][\sectiontitle][]{}{\MakeUppercase{\chaptername} \NUMBERstring{chapter}}{}

\titleformat{\chapter}[display]{\bfseries\normalsize\filcenter}{\chaptername \Numberstring{chapter}}{1\baselineskip}{}

\chapter{A first chapter}

\section{A first section}
