LaTeX Page Layout
\documentclass is also used by LaTeX to format the LaTeX page layout of a LaTeX document.
Page Elements
The typical page elements are body, running header, running footer, and margin notes. Body is the type area of the LaTeX document. Above the type area is a runnng header and below the type area is a running footer. Both running header and running footer may be used for containing the page number, document and text information, and any other markers. The areas to the left and the right of body are margins, at which margin notes, such as remarks and annotations, can be contained.
Further, type area of body may be divided into columns in multi-column mode. And the margin area can also be divided into multiple margin note areas.
Examples
One-Sided Document
Code
\documentclass[a4paper]{article}
\usepackage[showframe]{geometry}
\geometry{paperheight=845pt,top=102pt,textheight=591pt}
\geometry{paperwidth=597pt,left=90pt,textwidth=418pt}
\geometry{paperheight=470pt,textheight=320pt}
\geometry{paperwidth=490pt,textwidth=310pt}
\usepackage{xcolor}
\usepackage{layout}
\colorlet{showframe}{red!50}
\makeatletter
\let\org@Gm@pageframes\Gm@pageframes

%\def\Gm@hrule{\color{red!20}\hrule height 1pt depth\z@ width\textwidth}%
%\def\Gm@vrule{\color{red!20}\vrule width 1pt height\textheight depth\z@}%
%\def\Gm@hruled{\color{red!20}\hrule height\z@ depth 1pt width\textwidth}%
\makeatother
\begin{document}
