[Tex/LaTex] Using `\headsep` with the geometry and fanchyhdr packages

geometryheader-footer

I thought that the text on the page was supposed to start \headsep below the header, but that does not seem to be the case when I use the geometry and fancyhdr packages

\documentclass{article}
\usepackage{geometry}
\usepackage{fancyhdr}
\fancypagestyle{foo}{\renewcommand{\headrulewidth}{1pt}\fancyhead[L]{\hrulefill\hspace{\fill}}}
\pagestyle{foo}
\geometry{includeall, vmargin=0pt, headheight=\baselineskip, headsep=72pt}
\begin{document}
\vspace*{-\headsep}\hrulefill\par
\vspace{\fill}
\end{document}

How much \vspace needs to be added so that the \hrulefill in the body lines up with the fanchyhdr rule? What about so the \hrulefill in the body lines up with the rule in \fancyhead[L]?

Best Answer

\hrulefill (unlike \hrule) starts a paragraph so you need

\documentclass{article}
\usepackage{geometry}
\usepackage{fancyhdr}
\fancypagestyle{foo}{\renewcommand{\headrulewidth}{1pt}\fancyhead[L]{\hrulefill\hspace{\fill}}}
\pagestyle{foo}
\geometry{includeall, vmargin=0pt, headheight=\baselineskip, headsep=72pt}
\begin{document}
\vspace*{\dimexpr-\topskip-\headsep-\baselineskip+0.4pt\relax}\hrulefill\par
\vspace{\fill}
\end{document}

[Tex/LaTex] Problem with margins using amsart and geometry packages

If you use the package layout you get a picture of the dimensions used by the amsart for laying out the page. The following document reproduces that layout using the geometry package:

\documentclass{amsart}    

\usepackage[marginratio=1:1,height=584pt,width=360pt,tmargin=117pt]{geometry}
\usepackage{lipsum}

\usepackage{layout}

\begin{document}
\layout
\lipsum[1-20]
\end{document}

In particular, the height and width specifications correspond to the \textheight and \textwidth produced by amsart. The marginratio makes the marigns even, and tmargin moves the text down appropriately.

The value of tmargin was obtained as follows. layout reports for amsart that \topmargin=22pt. To convert this to tmargin I added 1in = 72pt plus headheight=14pt to the 22pt. However, the resulting layout reported a \topmargin of 21pt, so I bumped the result up by 1pt, to get the required value. The geometry documentation says

tmargin has nothing to do with \topmargin

but the package only provides tmargin to set the corresponding space.

All the above is assuming US latter paper. The amsart class sets:

\headheight=8pt \headsep=14pt
\footskip=12pt
\textheight=50.5pc \topskip=10pt
\textwidth=30pc
\columnsep=10pt \columnseprule=0pt
\marginparwidth=90pt
\marginparsep=11pt
\marginparpush=5pt

and has

\DeclareOption{a4paper}{\paperheight 297mm\paperwidth 210mm
  \textheight 54.5pc }
\DeclareOption{letterpaper}{\paperheight 11in\paperwidth 8.5in }

So if you specify a4paper option then a different \textheight is used. Again the layout package will report it for you.

[Tex/LaTex] How to make pages after the first come out correctly with fancyhdr

If you don't set a proper head height, fancyhdr reports the following:

Package Fancyhdr Warning: \headheight is too small (XX.Xpt): 
 Make it at least YY.YYYYpt.
 We now make it that large for the rest of the document.
 This may cause the page layout to be inconsistent, however.

As such, the newly-set \headheight will be the same throughout the document. To avoid this, I've created the following minimal document that sets a consistent head height, adding a vertical space (gap) on the first page to simulate a larger header:

I've used geometry to adjust the page layout - it's just easier/more convenient.
