Document Styles and Style Options

There are four standard document styles available in LATEX:

article
intended for short documents and articles for publication. Articles do not have chapters, and when \maketitle is used to generate a title (see Section [*]) it appears at the top of the first page rather than on a page of its own.

report
intended for longer technical documents. It is similar to article, except that it contains chapters and the title appears on a page of its own.

book
intended as a basis for book publication. Page layout is adjusted assuming that the output will eventually be used to print on both sides of the paper.

letter
intended for producing personal letters. This style will allow you to produce all the elements of a well laid out letter: addresses, date, signature, etc.

These standard styles can be modified by a number of style options. They appear in square brackets after the \documentstyle command. Only one style can ever be used but you can have more than one style option, in which case their names should be separated by commas. The standard style options are:

11pt
prints the document using eleven-point type for the running text rather that the ten-point type normally used. Eleven-point type is about ten percent larger than ten-point.

12pt
prints the document using twelve-point type for the running text rather than the ten-point type normally used. Twelve-point type is about twenty percent larger than ten-point.

twoside
causes documents in the article or report styles to be formatted for printing on both sides of the paper. This is the default for the book style.

twocolumn
produces two column on each page.

titlepage
causes the \maketitle command to generate a title on a separate page for documents in the article style. A separate page is always used in both the report and book styles.

There is one further option which, while not standard to LATEX, is very useful in all European countries. The a4 option causes the output in all of the standard styles to be adjusted to fit correctly on A4 paper. LATEX was designed in America where the standard paper is shorter and slightly wider than A4; without this option you will find that your output looks a little strange.
