Page Layout ⇒ fancyhdr | Interferences with Change in Page Geometry

[jakob]

Hi all,

I have rather a question than a problem since it is not super necessary for my layout. I couldn't find any similar topic, but I apologize if I've overseen an analogous problem.

I am using two sided book class which results in a slight asymmetric layout of the pages. this is fine, now i wanted to change only the title page to a more centered style, setting both margins to the same width. i tried to do that with the geometry package, e.g.

Code: Select all

\newgeometry{left=1cm, right=1cm}
title page
\restoregeometry

The strange thing is, every time i insert those two lines, even if there is no code whatsoever in between, fancyhydr gives me the head height error for the rest of the document.

Code: Select all

Package Fancyhdr Warning: \headheight is too small (12.0pt): 
 Make it at least 14.49998pt.

I don't get this error if i erase the two lines which are supposed to change the margin width for only the first page. I don't get it.

So now I wanted to create a minimal example, and i get the error message even without changing geometry for the title page. So clearly something is wrong, but why do i not get the error for my full document?

Code: Select all

\documentclass[a4paper, 12pt]{book}

\usepackage[T1]{fontenc} 
\usepackage[utf8]{inputenc} 
\usepackage[ngerman, english]{babel} 
\usepackage{fancyhdr} % headings and footers. 
\usepackage[a4paper]{geometry}

\begin{document}

\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}} 
\renewcommand{\chaptername}{}
\renewcommand{\sectionmark}[1]{\markright{#1}{}} 
\fancyfoot{} %clear foot
\fancyfoot[LE,RO]{\thepage}
\fancypagestyle{plain}{ %for chapter titles
	\fancyhf{} 
	\fancyfoot[LE,RO]{\thepage}
	\renewcommand{\headrulewidth}{0pt}
	}

\pagestyle{empty}
\newgeometry{left=1cm, right=1cm}
\vspace*{2cm}
\begin{otherlanguage*}{ngerman}
\begin{center}
\LARGE
my thesis title\\[3cm]
\normalsize
\end{center}
\end{otherlanguage*}
\restoregeometry
\cleardoublepage

\pagestyle{fancy}
\chapter{Lorem ipsum}

\end{document}

I could obviously avoid the error by simply using

Code: Select all

\usepackage[a4paper, headheight=15pt]{geometry}

but i also want to understand why i get it in the first place...

thanks for any feedback,
