Document Class
\documentclass[options]{class}
class
The document class. The standard classes are: article, report, book,
letter, and slides.
options
A list of one or more options, separated by commas - with no spaces.
The options recognized by the standard document classes are listed below.
Alternatives, at most one of which should appear, are separated by the
symbol '|'.
- 10pt|11pt|12pt
Chooses the normal (default) type size of the document. The default is
10pt, which selects ten-point type. (These options are not
recognized by the slides class).
- letterpaper|legalpaper|executivepaper|a4paper|a5paper|b5paper
Causes the output to be formatted for the appropriate paper size.
The default is letterpaper.
- landscape
Causes the output to be formatted for landscape (sideways) printing on the
selected paper size. This option effectively interchanges the width and
height dimensions of the paper size.
- final|draft
If TeX has trouble finding good places to break lines, it can produce
lines that extend past the right margin ('overfull hboxes'). The
draft option causes such lines to be marked by black boxes in the
output. The final option, which does not mark these lines, is the
default.
- oneside|twoside
Formats the output for printing on one side or both sides of a page. The
default is oneside, except that is is twoside for the
book class. (The twoside options cannot be used with the
slides document class.
- openright|openany
Specifies that chapters must begin on a right-hand page
(openright) or may begin on any page (openany). These
options apply only to the report class (whose default is
openany) and the book class (whose default is
openright).
- onecolumn|twocolumn
Specifies one-column or two-column pages. The default is
onecolumn. (The <twocolumn option cannot be used with the
slides class.)
- notitlepage|titlepage
The titlepage option causes the \maketitle command to
make a separate title page and the abstract environment to put
the abstract on a separate page. The default is titlepage for all
classes except article, for which it is notitlepage.
(These options are not recognized by the letter class.)
- openbib
Causes the bibliography to be formatted in open style (This option is not
recognized by the letter and slides classes).
- leqno
Puts formula numbers on the left side in equation and
eqnarray environments.
- fleqn
Left-aligns displayed formulas
Putting an option in the \documentclass command effectively adds
that option to any package (loaded with \usepackage command) that
recognizes it. LaTeX issues a warning message if a document-class option is
recognized neither by the document class nor by any loaded package.
