[Tex/LaTex] Format title for \chapter*{}

chaptersformattinghorizontal alignmenttitlesec

I have formatted Chapter titles using the package titlesec, but the formatting is unsuccessful in applying to my chapters with an asterisk *, (those chapters which I do not want appearing in my table of contents.)

That is, I would like to center and make \huge a title which corresponds to \chapter*{Some Title}.

For all my other chapters, I have successfully used:

 \titleformat{\chapter}[display]
{\normalfont\huge\bfseries}{\centering\chaptertitlename\ \thechapter}{20pt}{\huge}

How may I do this for \chapter*{}, using titlesec or otherwise?

This is under \documentclass{report}.

EDIT:

\documentclass[12pt]{report}

\usepackage{tocloft}
\usepackage{titlesec}

\begin{document}

\titleformat{\chapter}[display]
{\normalfont\huge\bfseries}{\centering\chaptertitlename\ \thechapter}{20pt}{\huge}

\tableofcontents{}

\addcontentsline{toc}{chapter}{Unnumbered Title}
\chapter*{Unnumbered Title}
I would like the title above centered

\chapter{Numbered Title}
...centered like this chapter heading above

\end{document}

Thank you!

You can have what you want with the numberless key. I'm not sure whether you want unnumbered chapters to be in the table of contents; the below code does it, but it's easy to undo it if you don't want. Just use:

\titleformat{\chapter}[display] {\normalfont\huge\bfseries\filcenter}{\chaptertitlename\ \thechapter}{20pt}{}
\titleformat{name=\chapter,numberless}[block] {\normalfont\huge\filcenter\bfseries}{}{0pt}{\huge}[\addcontentsline{toc}{chapter}{\chaptertitle}]

Turn on this chapter prefix by loading the class with the chapterprefix option. For details please have a look at the »KOMA-Script« user guide.

\documentclass[chapterprefix=on]{scrbook}
\usepackage[T1]{fontenc}
\usepackage{blindtext}

[Tex/LaTex] customizing chapter title format in classicthesis

The following example code shows where to insert the modifications required (the relevant lines of code are marked with % change color and size here). I used a shade of green and \huge, but of course you can use the attributes that best suit your needs:

 \documentclass[
   twoside,
   openright,
   titlepage,
   numbers=noenddot,
   headinclude, 
   footinclude=true,
   cleardoublepage=empty,
   abstractoff, 
   BCOR=5mm,
   paper=a4,
   fontsize=11pt,
   ngerman,
   american
   ]{scrreprt} 
\input{classicthesis-config}
\usepackage{lipsum}

\makeatletter
\ifthenelse{\boolean{@linedheaders}}%
    {% lines above and below, number right
    \titleformat{\chapter}[display]%             
        {\relax}
        {\raggedleft{\color{halfgray}\chapterNumber\thechapter} \\ }
        {0pt}%
        {\color{green!70!black}\huge\titlerule\vspace*{.9\baselineskip}\raggedright\spacedallcaps}% change color and size here 
        [\normalcolor\normalsize\vspace*{.8\baselineskip}\titlerule]%
    }
    {% something like Bringhurst  
    \titleformat{\chapter}[display]%
        {\relax}
        {\mbox{}\oldmarginpar{\vspace*{-3\baselineskip}\color{halfgray}\chapterNumber\thechapter}}
        {0pt}%
        {\color{green!70!black}\huge\raggedright\spacedallcaps}% change color and size here
        [\normalcolor\normalsize\vspace*{.8\baselineskip}\titlerule]% 
    }
\makeatother    
\begin{document}

\pagestyle{scrheadings}
\part{Introduction}
\chapter{First chapter}
\section{First section}
\lipsum[1-18]

\end{document}

The result:

Do not make the changes in the original .sty files (this is never recommended); do them in your .tex file surrounded with \makeatletter, \makeatother, as in my example code.
