How to Create a Brand Style Guide (Even a Simple One)

29 June 2026·4 min read

Quick answer: A brand style guide doesn't need to be a 40-page corporate document — even a solo business needs one page that locks in your colours (with hex codes), your two fonts, your logo rules and three or four words that describe how you sound. That one page stops every new flyer, post and email looking like it came from a different business. Below is the one-page template we use with clients, three real examples, and where consistency actually matters most. ✨

Most small businesses don't have a "brand" problem — they have a "nobody wrote it down" problem. The founder knows the brand colours are supposed to be blush and navy, but the person doing this month's Canva post doesn't, so it drifts. A style guide isn't about looking corporate. It's about looking like the same business every time. 💖

First, what most businesses get wrong

Keeping it all in someone's head — if your brand only exists as "what looks right" to the founder, it breaks the moment anyone else touches your marketing.
Copying hex codes from memory — "kind of that blue" isn't a colour. Screenshot drift is real, and it's the fastest way to a mismatched website, business card and Instagram grid.
Over-building it — a 40-page guide nobody opens is worse than no guide. If it's not one page you'd actually check before making a flyer, it won't get used.
Skipping tone of voice — most guides cover colours and fonts and stop. But "sounds like us" matters just as much, and it's the part almost nobody writes down.

The one-page style guide template

Copy this structure into a doc or a single Canva page — that's genuinely enough for most small businesses:

Colours: Primary + 2 secondary, each with a hex code.
Fonts: One heading font, one body font (plus fallback web-safe options).
Logo rules: Minimum size, clear space around it, and 2–3 things never to do (stretch it, recolour it, add a drop shadow).
Voice: 3–4 words describing how you sound (e.g. "warm, direct, a little cheeky, never salesy").
One do / one don't example of the brand applied correctly and incorrectly.

That's the whole thing. Anyone on your team — or any contractor you hire — should be able to open it and match your brand in under two minutes.

Three real examples

Notice how differently "consistent" looks depending on the industry — a style guide isn't one universal aesthetic, it's whatever reinforces trust for your specific clients. 📈

Accounting firm: Navy and a single accent colour, one clean sans-serif font, voice notes reading "plain-English, reassuring, never jargon-heavy." Every invoice, proposal and LinkedIn post uses the same two fonts — clients notice competence in small, repeated details.

Financial planner: A calm, muted palette (sage, cream, charcoal) with a serif heading font for gravitas and a simple sans-serif body font for readability. Voice notes: "steady, honest about risk, never hypey" — because overpromising is the fastest way to lose trust in this industry.

Physiotherapy clinic: A soft, energetic palette (teal, coral) with a rounded, friendly font. Voice notes: "encouraging, straightforward, never condescending" — patients respond to warmth, but they also need to trust the clinical competence behind it.

Where consistency actually matters most

You don't need every touchpoint pixel-perfect. Focus your effort on the handful of places new customers actually judge you: your website homepage, your Google Business Profile, your Instagram grid, and your invoices or proposals. A slightly-off internal document matters far less than a website banner in the wrong font next to an Instagram post in a different one — because that's the comparison a prospective client is actually making, often within the same five minutes.

💡 Heads up: Save your style guide somewhere every current and future team member can find it — a shared Google Doc or Drive folder, not a file buried on one laptop. The guide is only useful if the person making next week's social post actually has access to it.

Mistakes that quietly undo a style guide

Never updating it — if you tweak your palette or add a new font, the guide needs updating the same day, not "eventually."
Using too many fonts — two is plenty. A third "just for emphasis" is how consistency quietly unravels.
Ignoring photography style — bright and airy vs moody and dark says as much about your brand as your colours do, and it's often left out entirely.
Treating it as decoration, not a rulebook — the guide only works if everyone actually checks it before publishing, not just when someone remembers.

Frequently asked questions

Do I really need a style guide if it's just me running the business?

Yes — mostly to protect your future self. Six months from now you won't remember the exact hex code or which font you used for that one great flyer. A one-page guide means you're not reverse-engineering your own brand every time.

What's the minimum a style guide should include?

Colours with hex codes, two fonts, basic logo rules and a few words on tone of voice. That covers the majority of consistency problems most small businesses actually run into.

Should I hire a designer to build my style guide?

Not necessarily for the guide itself — you can document existing brand decisions yourself. A designer earns their fee more when they're helping you make the original decisions (palette, fonts, logo), not just writing them down afterward.

How often should a style guide be updated?

Whenever something in it changes — a new font, a refined palette, a shift in tone. Otherwise, a quick annual check is enough to make sure it still matches the business you've become. 🌴
