A style guides guide helps teams produce consistent, professional content every time. Whether a company publishes blog posts, marketing emails, or technical documentation, a style guide acts as the single source of truth for voice, tone, and formatting decisions. Without one, teams end up with mismatched content that confuses readers and weakens brand identity.
This article explains what a style guide is, why teams need one, and how to build a practical guide that actually gets used. It also covers the key elements every style guide should include and offers tips for keeping it current as a brand grows.

What Is a Style Guide?
A style guide is a document that defines rules for creating content. It covers writing standards like grammar preferences, punctuation rules, and word choices. It also includes visual guidelines such as logo usage, color palettes, and typography.
Think of a style guide as a rulebook for brand communication. It tells writers whether to use the Oxford comma. It tells designers which shade of blue represents the brand. It tells everyone on the team how to spell the company name correctly.
Style guides come in different forms. Some focus purely on editorial standards, these are called editorial style guides. Others cover visual identity and are known as brand style guides. Many organizations combine both into one comprehensive document.
A well-built style guide answers common questions before they arise. Should product names be capitalized? Is it okay to use contractions? How should dates be formatted? When team members can find these answers quickly, they spend less time asking questions and more time creating content.
Why Every Team Needs a Style Guide
Consistency builds trust. When a brand sounds different across every touchpoint, readers notice. A style guide ensures that blog posts, social media updates, and customer emails all feel like they come from the same source.
Here’s what happens without a style guide:
- One writer capitalizes “Email Marketing” while another writes “email marketing”
- Customer support uses a casual tone while the website sounds formal
- Different designers use slightly different versions of the logo
These inconsistencies make a brand look disorganized. They also create confusion for readers who expect a unified experience.
A style guide solves these problems by setting clear expectations. New team members can onboard faster because they have a reference document. Freelancers and agencies can match the brand voice without extensive training. Content reviews become quicker because editors check against documented standards rather than personal preferences.
Style guides also save time. When teams debate whether to write “10” or “ten,” they waste energy on decisions that should be automatic. A style guide makes these calls once, so everyone can move forward.
For growing teams, a style guide becomes even more valuable. As more people create content, the risk of inconsistency multiplies. A solid style guide keeps everyone aligned, no matter how large the team becomes.
Key Elements to Include in Your Style Guide
Every style guide should cover the essentials that affect daily content creation. Here are the key elements to include:
Brand Voice and Tone
Define how the brand sounds. Is it friendly or formal? Playful or serious? Include examples of phrases to use and phrases to avoid. Show the difference between appropriate tone for different contexts, a tweet might sound more casual than a white paper.
Grammar and Punctuation Rules
Document specific preferences. State whether the team uses the Oxford comma. Clarify how to handle em dashes, ellipses, and quotation marks. Reference an established style guide like AP or Chicago as a baseline, then note any exceptions.
Word List and Terminology
Create a list of commonly used terms with their correct spellings and capitalizations. Include industry jargon, product names, and any words the brand uses in specific ways. Note which terms to avoid entirely.
Formatting Standards
Specify how to format headlines, subheadings, bullet points, and numbered lists. Include rules for date and time formats, numbers (when to spell out vs. use numerals), and abbreviations.
Visual Guidelines
If the style guide covers design elements, include logo specifications, color codes (hex, RGB, and CMYK values), approved fonts, and image guidelines. Show correct and incorrect usage examples.
Examples
Abstract rules are hard to follow. Include before-and-after examples that show style guide principles in action. Real samples help writers understand expectations better than definitions alone.
How to Create a Style Guide Step by Step
Building a style guide doesn’t require months of work. Follow these steps to create a practical document that teams will actually use.
Step 1: Audit Existing Content
Review current content across all channels. Identify inconsistencies in voice, formatting, and terminology. Note which style choices work well and which cause problems. This audit reveals what the style guide needs to address.
Step 2: Choose a Foundation
Select an established style guide as a starting point. AP Style works well for marketing and journalism. Chicago Manual of Style suits academic and book publishing. Microsoft Style Guide fits technical writing. Building on an existing foundation saves time and provides comprehensive coverage for issues the team hasn’t considered yet.
Step 3: Document Brand-Specific Rules
Add rules unique to the brand. Define the voice, list proprietary terms, and note any departures from the foundation guide. These brand-specific rules make the style guide truly useful for the team.
Step 4: Organize for Easy Access
Structure the guide so people can find answers quickly. Use clear headings, a searchable format, and a table of contents. Consider organizing by topic (grammar, formatting, voice) rather than alphabetically.
Step 5: Get Team Input
Share a draft with writers, editors, and designers. Ask what questions they encounter regularly. Their input ensures the style guide addresses real needs rather than theoretical concerns.
Step 6: Publish and Distribute
Make the style guide easy to access. A shared document or internal wiki works better than a PDF buried in a folder. Announce the guide to the team and explain where to find it.
Tips for Maintaining and Updating Your Style Guide
A style guide is a living document. It needs regular attention to stay relevant and useful.
Assign an owner. Someone should be responsible for maintaining the style guide. This person reviews suggestions, makes updates, and communicates changes to the team. Without clear ownership, style guides become outdated.
Schedule regular reviews. Set a quarterly or biannual review cycle. During each review, check for outdated information, add new terms, and remove rules that no longer apply. Industry standards shift, and brand voice may evolve, the style guide should keep pace.
Track questions. When team members ask style-related questions, document them. Recurring questions indicate gaps in the style guide. Add answers to prevent the same questions from arising repeatedly.
Version control matters. Note when updates occur and what changed. This history helps team members understand why certain rules exist. It also prevents confusion when someone references an older version.
Keep it accessible. If the style guide is hard to find, people won’t use it. Place it somewhere central and remind the team periodically that it exists. Some teams pin it in Slack channels or add it to onboarding checklists.
Don’t over-engineer. A 100-page style guide intimidates more than it helps. Focus on rules that address frequent decisions. Add complexity only when necessary. A concise style guide that people actually read beats a comprehensive one that gathers dust.
