Style Guide
01 Definition
Style Guide meaning: A reference document that sets the rules for how a brand writes and formats content.
A style guide records the language, grammar, spelling, tone, and formatting choices a team should follow. Writers and editors use it to keep content consistent across pages, authors, and channels. It often builds on a public guide such as AP or Chicago, then adds brand-specific rules and word lists.

Why it matters
How Style Guide fits the work
A shared style guide lets many writers sound like one voice, cuts back-and-forth editing, and helps new contributors match brand standards faster.
In context
The style guide told writers to use 'sign in' as a verb, spell out numbers under ten, and avoid exclamation points in help articles.
Practical note
A style guide only helps if people can find and use it. Keep it short, searchable, and current, and pair it with real examples rather than long lists of rules.
