Good brand guidelines answer the questions people actually ask: which logo, which colours, what should this sound like, and who do I check with? Include the rules that prevent real mistakes, show them on real examples, and leave out anything nobody will use. A shorter document that people open beats a long one that sits in a folder.
Start with who will use it
A designer, a freelance writer, a printer and a social media manager need different things. List your real users and their typical questions first. Guidelines built around those questions are shorter and get used. NN/g’s overview of design systems makes a related point: a style guide covers branding, content guidance such as tone of voice, and visual standards, and usage instructions are necessary or the system is applied inconsistently.
What to include
| Section | What it should contain |
|---|---|
| Brand foundation | Purpose, audience, positioning and a few personality traits, in short form |
| Logo | Versions, clear space, minimum size, backgrounds, and a few examples of misuse |
| Colour | Primary and secondary palette with exact values for screen and print, and rules for when each is used |
| Typography | Typeface names, weights, roles (headings, body, interface) and a size hierarchy |
| Imagery | Style direction, subject matter, treatment, and what to avoid |
| Voice and tone | Principles, vocabulary choices, examples of on-brand and off-brand wording |
| Layout and spacing | Grid, margins and how elements sit together |
| Applications | The system on real items: a web page, social post, email, signage, a document |
| Accessibility | Contrast and legibility rules |
| Governance | Who owns it, who approves exceptions, where current files live |
Make the accessibility rules specific
Colour pairings should be tested, not guessed. The W3C’s contrast minimum criterion requires at least 4.5:1 for normal text and at least 3:1 for large text, where large means 18 point or 14 point bold. State the approved text and background combinations in your colour section so nobody has to calculate it.
Learn from published style guides
Mailchimp publishes its content style guide openly. It is organised by topic and searchable, and it covers goals and principles, voice and tone, grammar, web elements, writing for accessibility, writing for translation, and copyright and trademarks. Notice the structure: it is a set of answers to specific questions, not a story. It is licensed for non-commercial reuse with credit, so use it as a model for structure, not as text to copy.
What to leave out
- Long brand history. A paragraph is enough. Nobody needs the founding story to place a logo.
- Rules nobody will enforce. If you cannot check it, drop it.
- Every possible application. Show the important ones, then explain the principle.
- Trend-driven detail. If a rule will date within a year, keep it out of the core document.
- Duplicated copies. One live source avoids conflicting versions.
- Unverified claims. Do not publish statistics or promises as brand messaging without evidence. Under Australian Consumer Law, businesses must be able to back up the claims they advertise, and guidelines are a good place to set an approval rule for claims.
Make it usable
- Make it findable. A searchable web page or a short document with a clear index suits most teams.
- Provide the files. Logo files in the formats people need, colour swatches and templates sit beside the rules.
- Show examples. Right and wrong side by side teach faster than text.
- Name an owner and a review date. Guidelines age. Design systems, as NN/g notes, are not a one-and-done solution.
- Link rules to tools. Templates in design and document software enforce the rules without people reading them.
Where guidelines meet the wider system
Guidelines are the reference. Keeping a brand consistent across web, social, video and email also needs templates, tokens and review habits, which building a consistent visual identity across channels covers. If you are asking why a brand feels cheap or refined, what makes a brand look premium offers a practical audit, and building a campaign around one creative idea shows how a brand idea flows into campaigns.
