[Tex/LaTex] Multiline title vertical alignment using classicthesis and arsclassica

classicthesissectioningtitlesecvertical alignment

I would like to align the 2nd line of my title to have the same baseline with the chapter number. What I have now is enter image description here

, but I would like to haveenter image description here

instead.

I found that the tweak in How to get multi-line chapter name with ClassicThesis package? still leave the alignment problem (and I can't comment there), which are either change the \titleformat{\chapter}[block] to \titleformat{\chapter}[hang] or
the use of tabularx package, which results in
enter image description here

Although it does look better, but IMHO doesn't look quite right.

My MWE:

\documentclass[english,fontsize=11pt,paper=a4,twoside,openright,titlepage,numbers=noenddot,headinclude,BCOR=5mm,footinclude=true,cleardoublepage=empty]{scrreprt}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\setcounter{tocdepth}{3}

\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
% Classic Thesis Style loader
\makeatother
\input{classicthesis-config.tex}
\usepackage{arsclassica}
\makeatletter
% use Latin Modern instead of Computer Modern sans serif
\renewcommand{\sfdefault}{lmss}

\makeatother

\usepackage{babel}
\begin{document}

\chapter{Conclusions and Recommendations}
\end{document}

, where by the classicthesis-config.tex is exactly the same as the LyX version in https://code.google.com/p/classicthesis/. Here, in the MWE the font is different, but I just leave that since it's not relevant.

Does anybody have an idea?

Best Answer

One possibility would be to use \formatchapter with two minipages (one for the number, the other for the title) with bottom alignment:

\documentclass[english,fontsize=11pt,paper=a4,twoside,
openright,titlepage,numbers=noenddot,
headinclude,BCOR=5mm,footinclude=true,
cleardoublepage=empty]{scrreprt}

\input{classicthesis-config.tex}
\usepackage{arsclassica}
\usepackage{babel}
\renewcommand{\sfdefault}{lmss}

\renewcommand\formatchapter[1]{% 
  \begin{minipage}[b]{0.15\linewidth}
    \chapterNumber
  \end{minipage}%
  \begin{minipage}[b]{0.6\linewidth}
    \raggedright\spacedallcaps{#1}
  \end{minipage}
} 

\begin{document}

\chapter{Conclusions and Recommendations}

\chapter{A Really Long Example Title Spanning Three Lines}

\end{document}

I suppressed parts of the example code that were not relevant to the problem discussed.
