How to Create a Social Media Style Guide (With Template)
By PostMediaAI5 min read
Short answer: a social media style guide is a short document that tells anyone posting for your brand how to sound and look. It covers your accounts and audience, voice and tone, words to use and avoid, grammar and formatting rules, emoji and hashtag use, visual standards, how to reply to comments, and legal or disclosure rules. Keep it to a few pages with real examples, and update it when a question comes up twice.
Sprout Social’s and Hootsuite’s guides list a similar set of sections — profiles, voice, language, formatting, hashtags, visuals, customer care and legal considerations — with Hootsuite also adding rules for AI use (sproutsocial.com and blog.hootsuite.com).
Why a style guide saves time
- New team members and freelancers can post on brand from day one.
- Reviewers check against written rules instead of personal taste, which shortens feedback.
- Recurring debates (emoji or not? Oxford comma?) are settled once.
- AI drafts are easier to edit into your voice when the voice is written down.
What to include, section by section
1. Accounts and audience
List every account, its handle and its job (for example, “LinkedIn Page: hiring and B2B updates; Instagram: product and behind-the-scenes”). Describe the audience for each in one or two sentences.
2. Voice and tone
Voice is constant; tone adapts to the moment. Pick three voice words with a “this, not that” for each — “friendly, not jokey”, “expert, not academic”, “direct, not blunt”. Then describe how tone shifts: lighter for everyday posts, calmer and plainer for complaints or sensitive news.
3. Words to use and avoid
- How to write your brand and product names (capitals, spacing, never abbreviated).
- Preferred terms (“customers” or “members”? “book” or “reserve”?).
- Banned words and claims: superlatives you cannot prove, competitor names, jargon your audience does not use.
- Inclusive language choices.
4. Grammar and formatting
- Spelling standard (US or UK English, for example).
- Sentence case or title case for headlines and video titles.
- Numbers, dates, times and time-zone format.
- Line breaks, lists and how long captions should be per network.
- Link placement and whether to use link shorteners.
5. Emoji and hashtags
Say whether you use emoji, which ones fit, and how many per post. For hashtags, list your branded tags, how many to use per network, where they go (in the caption or at the end),, and the casing rule for multi-word tags (for example #SaturdayLoaves rather than #saturdayloaves, which is easier to read).
6. Visual standards
- Logo usage, colours and fonts (link to your brand kit).
- Photo style: lighting, people, backgrounds, what to avoid.
- Templates for recurring formats: quotes, tips, announcements.
- Video rules: captions on, first-seconds hook, aspect ratio per network.
- Alt text rules: always add it where supported, describe what matters.
7. Community and replies
How fast you aim to reply, how to sign replies, when to move a conversation to private messages, how to handle complaints, what to hide or delete, and when to escalate to a manager.
8. Legal, disclosure and AI rules
- Disclosure of sponsored, gifted and affiliate content; in the US, follow the FTC’s guidance (ftc.gov).
- Permission rules for user content, customer names and photos of people.
- Topics you do not comment on.
- How AI may be used: for example, first drafts only, every fact checked, no AI images of real people.
Per-network notes
Add a short line for each network you use, because the same voice sounds different in different places. Examples of the kind of note that helps:
- LinkedIn: lead with the point in the first line; short paragraphs; few or no emoji; hashtags at the end, if any.
- Instagram: caption supports the visual; key message in the first line; branded hashtag plus a few relevant ones.
- TikTok and Shorts: hook in the first seconds; on-screen text matches the spoken script; caption is short.
- X, Threads and Bluesky: one idea per post; threads only when each post stands on its own.
- Discord, Slack and Telegram communities: announcements in plain language, no hard sell, link to details.
These are house-style examples, not platform rules; write the version that fits your brand and audience.
Fill-in social media style guide template
- Brand in one sentence: We help [audience] [do what] by [how].
- Accounts: [network] — [handle] — [job] — [audience].
- Voice: [word], not [word] / [word], not [word] / [word], not [word].
- Tone shifts: everyday [ ], celebrations [ ], complaints [ ], sensitive news [ ].
- Names: brand written as [ ]; products written as [ ].
- Use: [terms]. Avoid: [terms and claims].
- Spelling standard: [ ]. Headline case: [ ]. Date and time format: [ ].
- Emoji: [yes/no, which, how many]. Hashtags: [branded tags, number per network, placement].
- Visuals: brand kit link [ ]; photo style [ ]; templates [ ]; alt text rule [ ].
- Replies: target time [ ]; sign-off [ ]; escalation contact [ ].
- Disclosures and permissions: [rules].
- AI use: [rules].
- Example posts: [two or three posts that are exactly right, with a note on why].
Example: “this, not that” in practice
For an illustrative bakery whose voice is “warm, not cutesy”: “Saturday’s loaves are on the bench. Come by from 9, or pre-order tonight.” fits. “OMG carb lovers!!! 🥖🥖🥖 You do NOT want to miss this!!!” does not. Two lines like this teach new writers more than a page of adjectives. Add a pair for each tone shift, too, such as a good and a bad reply to a complaint.
Keeping the guide alive
- Keep it short; a guide nobody reads is worse than none.
- Store it where posts are written, and link it from your calendar.
- Add an example every time a reviewer gives the same feedback twice.
- Review it once or twice a year, or after a rebrand.
Using your style guide with PostMediaAI
In PostMediaAI, AI gives you a first draft for each channel from a topic or link, and you edit it in your own voice before scheduling (postmediaai.com). Your style guide is what makes that edit fast: check the draft against your voice words, banned terms and hashtag rules, and use the built-in rewrites like “Shorter” or “More casual” to get closer before you fine-tune. Your team works from one shared calendar and media library, so approved templates and visuals are in one place (postmediaai.com). For keeping AI drafts on-voice, see How to Keep Your Brand Voice When AI Writes Your Posts; for the wider content approach, Social media content strategy: audience, pillars, and a plan you can keep.
FAQ
What is a social media style guide?
A document that sets how your brand sounds and looks on social media — voice, words, formatting, hashtags, visuals, replies and legal rules — so everyone posts consistently.
What is the difference between brand guidelines and a social media style guide?
Brand guidelines cover your whole identity (logo, colours, typography, mission). A social media style guide applies them to day-to-day posting: captions, hashtags, emoji, replies and per-network formats.
How long should a social media style guide be?
Short enough to read in ten minutes. Two to five pages with examples usually covers a small brand; link out to the full brand kit for visual detail.
