# Header layout for multilines title using fancyhdr

My current header looks like this. The second line of the header is touching the dividing line. My question is how to move the text upwards or the dividing line downwards so that the format looks nicer.

The code in the main file is

\documentclass{book}
\usepackage{fancyhdr}

\pagestyle{fancy} %set header type
\begin{document}
\chapter{Open Top Frustum Shells under Vertical Uniform Load}
\chaptermark{\protect\parbox{.55\textwidth}{Open Top Frustum Shells under Vertical Uniform Load\strut}}
\end{document}

• Note the titlesec package has a newlinestospace option which converts any line break in titles to spaces for the header. – Bernard Mar 8 '16 at 11:13

• @bernard Thank you for your comment. touhami's method works perfectly. – Bob Mar 9 '16 at 11:12

This because of the parbox. A solution is by adding \strut

\documentclass{book}
\usepackage{fancyhdr}

\pagestyle{fancy} %set header type
