A style guide is a set of standards for the writing, formatting, and design of documents. [1] A book-length style guide is often called a style manual or a manual of style (MoS or MOS). A short style guide, typically ranging from several to several dozen pages, is often called a style sheet. The standards documented in a style guide are applicable for either general use, or prescribed use in an individual publication, particular organization, or specific field.
A style guide establishes standard style requirements to improve communication by ensuring consistency within and across documents. They may require certain best practices in writing style, usage, language composition, visual composition, orthography, and typography by setting standards of usage in areas such as punctuation, capitalization, citing sources, formatting of numbers and dates, table appearance and other areas. For academic and technical documents, a guide may also enforce the best practice in ethics (such as authorship, research ethics, and disclosure) and compliance (technical and regulatory). For translations, a style guide may even be used to enforce consistent grammar, tones, and localization decisions such as units of measure. [2]
Style guides may be categorized into three types: comprehensive style for general use; discipline style for specialized use, which is often specific to academic disciplines, medicine, journalism, law, government, business, and other industries; and house or corporate style, created and used by a particular publisher or organization.

Style guides vary widely in scope and size. Writers working in large industries or professional sectors may reference a specific style guide, written for usage in specialized documents within their fields. For the most part, these guides are relevant and useful for peer-to-peer specialist documentation or to help writers working in specific industries or sectors communicate highly technical information in scholarly articles or industry white papers.
Professional style guides of different countries can be referenced for authoritative advice on their respective language(s), such as the United Kingdom's New Oxford Style Manual from Oxford University Press; and the United States' The Chicago Manual of Style from the University of Chicago Press. Australia has a style guide, available online, created by its government. [4]
The variety in scope and length is enabled by the cascading of one style over another, analogous to how styles cascade in web development and in desktop cascade over CSS styles.
In many cases, a project such as a book, journal, or monograph series typically has a short style sheet that cascades over the larger style guide of an organization such as a publishing company, whose specific 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. Examples of industry style guides include:
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 British, American, Canadian, and Australian 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 as well as text.
Guides in specific scientific and technical fields may cover nomenclature to specify names or classifying labels that are clear, standardized, and ontologically sound (e.g., taxonomy, chemical nomenclature, and gene nomenclature).
Style guides that cover usage may suggest descriptive terms for people which avoid racism, sexism, homophobia, etc. Style guides increasingly incorporate accessibility conventions for audience members with visual, mobility, or other disabilities. [5]
Since the rise of the digital age, websites have allowed for an expansion of style guide conventions that account for digital behavior such as screen reading. [6] Screen reading requires web style guides to focus more intently on a user experience subjected to multichannel surfing. Though web style guides can also vary widely, they tend to prioritize similar values concerning brevity, terminology, syntax, tone, structure, typography, graphics, and errors. [6]
Most style guides are revised periodically to accommodate changes in conventions and usage. The frequency of updating and the revision control are determined by the subject. 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 6th editions, respectively, as of 2023. [update] Many house styles and individual project styles change more frequently, especially for new projects.
Desktop publishing (DTP) is the creation of documents using dedicated software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate page layouts and produce text and image content comparable to the simpler forms of traditional typography and printing. This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing.
The comma, is a punctuation mark that appears in several variants in different languages. Some typefaces render it as a small line, slightly curved or straight, but inclined from the vertical, others give it the appearance of a miniature filled-in figure 9 placed on the baseline. In many typefaces it is the same shape as an apostrophe or single closing quotation mark ’.
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. They come in four main pairs of shapes, as given in the box to the right, which also gives their names, that vary between British and American English. "Brackets", without further qualification, are in British English the (...) marks and in American English the [...] marks.
In English writing, quotation marks or inverted commas, also known informally as quotes, talking marks, speech marks, quote marks, quotemarks or speechmarks, are punctuation marks placed on either side of a word or phrase in order to identify it as a quotation, direct speech or a literal title or name. Quotation marks may be used to indicate that the meaning of the word or phrase they surround should be taken to be different from that typically associated with it, and are often used in this way to express irony. They are also sometimes used to emphasise a word or phrase, although this is usually considered incorrect.
Capitalization or capitalisation is writing a word with its first letter as a capital letter and the remaining letters in lower case, in writing systems with a case distinction. The term also may refer to the choice of the casing applied to text.
Linguistic prescription is the establishment of rules defining preferred usage of language. These rules may address such linguistic aspects as spelling, pronunciation, vocabulary, morphology, syntax, and semantics. Sometimes informed by linguistic purism, such normative practices often propagate the belief that some usages are incorrect, inconsistent, illogical, lack communicative effect, or are of low aesthetic value, even in cases where such usage is more common than the prescribed usage. They may also include judgments on socially proper and politically correct language use.
APA style is a writing style and format for academic documents such as scholarly journal articles and books. It is commonly used for citing sources within the field of behavioral and social sciences, including sociology, education, nursing, criminal justice, anthropology, and psychology. It is described in the style guide of the American Psychological Association (APA), titled the Publication Manual of the American Psychological Association. The guidelines were developed to aid reading comprehension in the social and behavioral sciences, for clarity of communication, and for "word choice that best reduces bias in language". APA style is widely used, either entirely or with modifications, by hundreds of other scientific journals, in many textbooks, and in academia. The current edition is its seventh revision.
A technical writer is a professional communicator whose task is to convey complex information in simple terms to an audience of the general public or a very select group of readers. Technical writers research and create information through a variety of delivery media. Example types of information include online help, manuals, white papers, design specifications, project plans, and software test plans. With the rise of e-learning, technical writers are increasingly hired to develop online training material.
In English-language punctuation, the serial comma, also referred to as the series comma, Oxford comma, or Harvard comma, is a comma placed immediately after the penultimate term and before the coordinating conjunction in a series of three or more terms. For instance, a list of three countries might be punctuated without the serial comma as "France, Italy and Spain" or with the serial comma as "France, Italy, and Spain". The serial comma can serve to avoid ambiguity in specific contexts, though its employment may also generate ambiguity under certain circumstances.
Technical writing is a specialized form of communication used by many of today's industrial and scientific organizations to clearly and accurately convey complex information to a user. An organization's customers, employees, assembly workers, engineers, and scientists are some of the most common users who reference this form of content to complete a task or research a subject. Most technical writing relies on simplified grammar, supported by easy-to-understand visual communication to clearly and accurately explain complex information.
Orthographic conventions have varied over time, and vary by publishers, authors, and regional preferences, on whether and when Internet should be capitalized. When the Internet first came into common use, most publications treated Internet as a capitalized proper noun, but this has become less common. This reflects the tendency in English to capitalize new terms and move them to lowercase as they become familiar. The word is sometimes still capitalized to distinguish the global IP-based internet from internets that are smaller or not IP-based, though many publications, including the AP Stylebook since 2016, recommend the lowercase form in every case. In 2016, the Oxford English Dictionary found that, based on a study of around 2.5 billion printed and online sources, "Internet" was capitalized in 54% of cases, with Internet being preferred in the United States and internet being preferred in the United Kingdom.
Sentence spacing concerns how spaces are inserted between sentences in typeset text and is a matter of typographical convention. Since the introduction of movable-type printing in Europe, various sentence spacing conventions have been used in languages with a Latin alphabet. These include a normal word space, a single enlarged space, and two full spaces.
MLA Handbook, formerly MLA Handbook for Writers of Research Papers (1977–2009), establishes a system for documenting sources in scholarly writing. It is published by the Modern Language Association, which is based in the United States. According to the organization, their MLA style "has been widely adopted for classroom instruction and used worldwide by scholars, journal publishers, and academic and commercial presses".
The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline. The most common versions are the en dash–, generally longer than the hyphen but shorter than the minus sign; the em dash—, longer than either the en dash or the minus sign; and the horizontal bar―, whose length varies across typefaces but tends to be between those of the en and em dashes.
The full stop, period, or full point. is a punctuation mark used for several purposes, most often to mark the end of a declarative sentence.
Sentence spacing guidance is provided in many language and style guides. The majority of style guides that use a Latin-derived alphabet as a language base now prescribe or recommend the use of a single space after the concluding punctuation of a sentence.
AMA Manual of Style: A Guide for Authors and Editors is the style guide of the American Medical Association. It is written by the editors of JAMA and the JAMA Network journals and is most recently published by Oxford University Press. It specifies the writing, editing, and citation styles for use in the journals published by the American Medical Association.
Capitalization or capitalisation in English grammar is the use of a capital letter at the start of a word. English usage varies from capitalization in other languages.
