Style guide

A style guide or manual of style is a set of standards for the writing, formatting and design of documents. It is often called a style sheet, although that term also has other meanings. The standards can be applied either for general use, or be required usage for an individual publication, a particular organization, or a specific field.

A style guide establishes standard style requirements to improve communication by ensuring consistency both within a document, and across multiple documents. Because practices vary, a style guide may set out standards to be used in areas such as punctuation, capitalization, citing sources, formatting of numbers and dates, table appearance and other areas. The style guide may require certain best practices in usage, language composition, visual composition, orthography and typography. For academic and technical documents, a guide may also enforce the best practice in ethics (such as authorship, research ethics, and disclosure), pedagogy (such as exposition and clarity), and compliance (technical and regulatory).

Style guides are specialized in a variety of ways, from the general use of a broad public audience, to a wide variety of specialized uses, such as for students and scholars of various academic disciplines, medicine, journalism, the law, government, business in general, and specific industries. The term house style refers to the individual style manual of a particular publisher or organization.


Style guides vary widely in scope and size.


This variety in scope and length is enabled by the cascading of one style over another, in a way analogous to how styles cascade in web development and in desktop cascade over CSS styles.

A short style guide is often called a style sheet. A comprehensive guide tends to be long and is often called a style manual or manual of style (MOS or MoS). In many cases, a project such as one book, journal, or monograph series typically has a short style sheet that cascades over the somewhat larger style guide of an organization such as a publishing company, whose content is usually called house style. Most house styles, in turn, cascade over an industry-wide or profession-wide style manual that is even more comprehensive. Some examples of these industry style guides include the following:

Finally, these reference works cascade over the orthographic norms of the language in use (for example, English orthography for English-language publications). This, of course, may be subject to national variety such as the different varieties of American English and British English.


Some style guides focus on specific topic areas such as graphic design, including typography. Website style guides cover a publication's visual and technical aspects along with text.

Style guides that cover usage may suggest ways of describing people that avoid racism, sexism, and homophobia. Guides in specific scientific and technical fields cover nomenclature, which specifies names or classifying labels that are preferred because they are clear, standardized, and ontologically sound (e.g., taxonomy, chemical nomenclature, and gene nomenclature).


Most style guides are revised from time to time to accommodate changes in conventions and usage. The frequency of updating and the revision control are determined by the subject matter. For style manuals in reference work format, new editions typically appear every 1 to 20 years. For example, the AP Stylebook is revised annually, and the Chicago, APA, and ASA manuals are in their 17th, 7th, and 4th editions, respectively. Many house styles and individual project styles change more frequently, especially for new projects.



Several basic style guides for technical and scientific communication have been defined by international standards organizations. One example is ISO 215 Documentation – Presentation of contributions to periodicals and other serials.[1]


The European Union publishes an Interinstitutional style guide – encompassing 24 languages across the European Union. This manual is "obligatory" for all those employed by the institutions of the EU who are involved in preparing EU documents and works.[2] The Directorate-General for Translation of the European Commission publishes its own English Style Guide, intended primarily for English-language authors and translators, but aiming to serve a wider readership as well.[3]

United Kingdom



United States

In the United States, style guide usage varies depending on the industry and purpose of the content. Some public corporations follow the The Associated Press Stylebook for content related to journalism (such as press releases), but use the Chicago Manual of Style for printed and digital documents, such as reports or website content. Many corporations create their own internal style manuals based on multiple style guides. Journalists use The Associated Press Stylebook. Book publishers and authors of journals requiring reference sections generally choose the Chicago Manual of Style, while other scholarly writing in the humanities often follows the MLA Style Manual and Guide to Scholarly Publishing.[10] One of the most popular grammar guides used in third-person writing is The Elements of Style.

Despite the near uniform use of the Bluebook, nearly every state has appellate court rules that specify citation methods and writing styles specific to that state  – and the Supreme Court of the United States has its own citation method. However, in most cases these are derived from the Bluebook.

There are also several other citation manuals available to legal writers in wide usage in the United States. Virtually all large law firms maintain their own citation manual and several major publishers of legal texts (West, Lexis-Nexis, Hein, et al.) maintain their own systems.
