Define different heights for head and foot

Question

is it possible to define different \headerheight for head and foot respectively? For example, there is a logo image in the header which needs a large \headerheight and only text is in foot which needs a small \headerheight. Or does it have two variables to control the heights of foot and head respectively?

Answer 1

if you want to see your page layout with the given values, then print it:

\documentclass[twoside]{article}
\usepackage{layout}
\begin{document}

\layout

\end{document}

Answer 2

The height of the header is given by \headheight (not \headerheight). The distance between the baseline of the header and the top of the page text is then given by \headersep.

The height of the footer is defined differently. The dimension \footskip states in what distance the baseline of the footer is set to the bottom of the page text. Have a look at the manuals of fancyhdr and geometry, both show a nice drawing explaining all page related dimensions.

If you use fancyhdr for your header and footer it tells you automatically which dimension is to small and to what value you have to set it. This can then be done using geometry:

\documentclass{article}
\usepackage[head=30pt,foot=<..>]{geometry}
\usepackage{fancyhdr}

\fancyhead{}
\fancyfoot{}
\fancyhead[c]{\Huge LOGO}
\fancyfoot[c]{Some normal text}
\pagestyle{fancy}
% Disable header and footer rules
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}

\begin{document}
 Text ...
\end{document}

Without the head= setting fancyhdr showed the following warning:

Package Fancyhdr Warning: \headheight is too small (12.0pt): 
 Make it at least 30.0pt.
 We now make it that large for the rest of the document.
 This may cause the page layout to be inconsistent, however.
