How to Create a Brand Style Guide for Social Media (Free Template)

Most small businesses do not have a brand style guide. Not because they do not know they should — they do — but because every template they find online was designed for a 50-person marketing team with a brand strategist, a creative director, and a print production workflow.

You do not need any of that. You need six things, on one page, written in plain language.

The rule behind this is simple: every brand decision you make once and write down is one you do not have to make again. The style guide is not a document you write once and frame. It is a decision log that stops you debating whether to use the navy or the teal every time you open Canva.

Here is the template.

Why you need one even as a one-person business

If it is just you posting, you might think the guide lives in your head. It does not. It lives in your head as a vague feeling, which means it changes slightly every week depending on your mood, what you saw on Instagram that morning, and whether you had enough sleep.

Three months in, your brand has quietly drifted. The early posts had a warm, direct tone. Recent ones sound more corporate because you have been reading competitor content. Your colour palette has acquired a fourth shade you do not remember choosing.

The style guide externalises the vague feeling into specific rules. Once it is written, you follow the rules instead of following your mood.

It also becomes the brief you hand to an AI content tool, a VA, or a freelancer — without spending two hours explaining "what we are about."

The 6-section template

Use this as a Google Doc. Give it a heading and a date at the top. Fill it in for your business. The whole thing should fit on one page. If it does not fit, you have written too much.

Below, each section is shown filled in for a fictional business: Hilltop Nursery, a children's day nursery in Nottingham. They post on Facebook, Instagram, and have recently started a LinkedIn page targeting local parents and HR managers at Nottingham employers.

1. Logo and visual identity

Write down which version of your logo is used in which context, and where the master files live.

Hilltop Nursery example:

What we never do: stretch the logo. Place it on a background that makes it hard to read. Use any version not in the /brand/logos/ folder on Google Drive.

Where master files live: Google Drive > Hilltop > Brand > Logos. Link here.

2. Colour palette

Three primary colours, two accent colours. Hex codes only — no "a kind of warm orange."

Hilltop Nursery example:

Three primary colours are enough for nearly every design decision. The accent colours exist for variation — use them sparingly, not on every post.

---

3. Typography

One display font for headlines and covers. One body font for captions, bios, and body copy. Name them and note where they are hosted.

Hilltop Nursery example:

• Display font: Playfair Display (Google Fonts). Use for: cover images, story headers, pull quotes.
• Body font: Inter (Google Fonts). Use for: captions, bio text, infographic body copy.

What we never use: Comic Sans, Impact, or any handwriting font that is not Playfair Display. No more than two fonts in any single piece of content.

You do not need custom fonts. Free Google Fonts work. What matters is consistency.

4. Tone of voice

Five adjectives that describe how you sound. Five words or phrases you never say. Plus a worked example so anyone reading this knows what it means in practice.

Hilltop Nursery example:

We sound: warm, reassuring, plain-spoken, specific, human.

We never sound: corporate, preachy, vague, salesy, overly formal.

We say:

• "your child"
• "our team"
• "what that looks like at Hilltop"
• "here's how we handle it"

We never say:

• "holistic childcare solutions"
• "child-centric pedagogy"
• "delivering exceptional outcomes"
• "passionate team of professionals"
• "going forward"

Worked example. Same message, two versions:

Generic: "Our passionate team of childcare professionals delivers a holistic learning environment designed to nurture every child's individual potential."

Hilltop voice: "Every child gets a key worker who knows them by name. Their interests, their friends, what makes them light up. That is how we start."

The second version is shorter, specific, and sounds like a person.

5. Image style

A rule someone else could follow. Not "nice photos" — that is not a rule.

Hilltop Nursery example:

Photography:

• Natural light only. Outdoor or well-lit indoor.
• Warm tones. No harsh flash.
• Children doing things: building, painting, laughing. Not posed or static.
• Wide shots showing the nursery garden and space. Tight shots showing faces and detail.
• Staff in shots where it adds warmth — never posed.

Graphics / designed posts:

• Leaf Green or Warm Cream backgrounds.
• One main message per graphic. Not three bullet points and a logo.
• Inter for body, Playfair for any headline.

What never appears:

• Stock photography of generic children (children must be from Hilltop, with signed consent on file).
• Dark or low-contrast images.
• Heavy text overlays.
• Photographs taken at weekends by staff on personal phones without parental consent confirmed.

The consent rule is not just good brand practice — it is a legal requirement for nurseries in the UK. Your "never appears" section should include anything with a compliance reason, not just aesthetic preferences.

---

6. What we never post

This is the section most templates skip. It is often the most valuable one.

Hilltop Nursery example:

• Never name children in public posts without the specific family's written permission for that post.
• Never comment on competitor nurseries — publicly or in the comments of any post.
• Never post during an active complaint, incident investigation, or OFSTED inspection.
• Never discuss Ofsted ratings, funding, or government policy in a way that could be read as political.
• No personal opinions from individual staff members published under the Hilltop account.

This section also covers legal and regulatory territory. For a nursery it is child safety and consent. For a financial services firm it is FCA regulated claims. For a food business it is allergen and health claims. Write the rules for your sector.

Where to store your style guide

You have three realistic options. Each has a trade-off.

Google Doc: free, shareable, searchable, works with any tool. Downside: no version history by default (use Document History), easy to accidentally edit.

Notion page: free to low cost, better formatting, embeds cleanly. Downside: another tool to log into; if your team does not already use Notion, it will not be checked.

Figma page: if you already use Figma for design, keep it there alongside your actual brand assets. Design team picks it up naturally. Downside: less accessible to non-designers.

Pick the tool your team actually uses every day. A Notion page that nobody opens is worse than a Google Doc everyone bookmarks.

Rheos connects directly to your style guide: when you set up your brand, Rheos stores your tone of voice, colour palette, and visual identity, and every post it generates respects those rules automatically. You do not need to brief it each time.

How often to update it

At minimum, once a quarter. In practice: every time you spot drift.

Drift looks like this: you are reviewing posts from three months ago and they feel more on-brand than your recent ones. That is a signal. Something in the way you have been creating content has shifted and the guide has not caught up.

The fix is not to rewrite the guide from scratch. It is to read the section that has drifted, edit the specific rule that is no longer accurate, and update the date at the top of the document.

Two rules:

1. If you break a rule on purpose, ask whether the rule should change.
2. If someone asks you a brand question and the answer is not in the guide, add it.

How to use it on social media

The guide does not help you unless you use it. Here is a one-minute check before posting:

• Does the image follow our photography or graphics rules?
• Would someone reading this caption say it sounds like our brand?
• Are there any words on the "never say" list in this post?
• Does this fall into "what we never post"?
• Are all visible hex codes and fonts from our defined palette?

That is five questions. If the answer to all five is yes, post it. If one is no, fix it first.

Frequently asked questions

Can I just use Canva's brand kit?

Canva's brand kit is a good start — it stores your logo, colours, and fonts and applies them to templates automatically. The problem is it covers only the visual layer. It does not capture tone of voice, the "never say" list, or what you never post. Use Canva's brand kit for the design elements, and keep a separate document for everything else.

How long should this take?

Two hours the first time, if you do it properly. One hour if you have already thought through your brand and just need to write it down. Do not let it become a project. Set a two-hour block, fill in each section, and publish the draft. Imperfect and done is more useful than perfect and unfinished.

What if my brand is still evolving?

Write down where it is now, even if it changes. A current guide you update beats a perfect guide you never write. Treat the document as a snapshot with a date, not a final statement of truth. The act of writing it will often clarify what is not yet resolved — which is exactly the right time to resolve it.
