Brand guidelines examples, and how to build your own
The fastest way to understand what good brand guidelines look like is to read great ones. The best are public, and they show how a company turns a logo, a color palette, a typeface, and a tone of voice into a system anyone can apply without the founders in the room.
Here are seven brand guidelines examples worth studying, what each one does well, and a practical way to build your own.
What brand guidelines include
A brand guidelines document, sometimes called a brand book or style guide, is the reference that keeps everyone making the brand look and sound consistent. A thorough one usually covers:
- Logo: usage, sizing, clear space, and what not to do.
- Color: primary and secondary palettes with exact hex, RGB, and CMYK values.
- Typography: typefaces, weights, and a type scale for headings and body.
- Imagery and iconography: photography style, illustration rules, icon sets.
- Layout and spacing: grids, margins, and composition rules.
- Motion: how things animate, for brands with digital products.
- Voice and tone: how the brand sounds in writing, and how that shifts by context.
- Accessibility: contrast ratios, alt text, and inclusive language.
The visual sections are usually the most detailed, because they’re the easiest to make hard rules for. A hex code is unambiguous. The best guidelines bring that same precision to the parts that are harder to pin down.
Brand guidelines examples worth studying
Uber. A tightly systemized visual identity, with composition, motion, and co-branding rules most companies never write down.
Spotify. A deliberately flexible system built for endless campaign variation without losing the brand, anchored by its dynamic color and duotone treatments.
Mailchimp. Its public Content Style Guide is the reference standard for documenting voice and tone, with concrete do-and-don’t writing examples.
Shopify Polaris. A design system that treats voice and tone as a first-class component, with content guidance sitting right next to the UI.
Atlassian Design System. Writing and design guidelines specific enough to ship with: grammar, terminology, and patterns for real product surfaces.
Google Material Design. The most comprehensive public design system, a reference for documenting components, motion, and accessibility at scale.
Apple Human Interface Guidelines. Decades of product design standards that show how to write rules teams actually follow.
Read past the logos and the strong ones share three habits. They’re specific (rules, not adjectives). They show, with real examples of right and wrong. And they treat words as seriously as visuals, documenting voice with the same rigor as the color palette. The prettiest PDF isn’t the most useful one. The most precise one is.
How to build your own brand guidelines
You don’t need a 90-page book to start. Build it in five passes:
- Audit what you already have: pull your logo files, colors, fonts, and a sample of your best writing.
- Define the system: lock the logo rules, exact color values, and type scale first, since everything else sits on them.
- Document each component with examples: show correct and incorrect use side by side, not just the rule.
- Write the voice and tone section properly, so the words are as governed as the visuals. The hard part is turning a feeling into instructions a writer can follow, which is its own skill (how to describe tone of voice walks through it).
- Make it usable and keep it living: put it where people work, and update it as the brand evolves.
Start with the parts people get wrong most often, ship a v1, and expand. If you’d rather not start from a blank page, a free brand guidelines template gives you the structure to fill in. A short guide people actually use beats a comprehensive one nobody opens.
What a strong voice and tone section includes
The voice and tone section is the one most guidelines treat lightly, and it’s worth getting right because it’s the part a competitor can’t copy. A usable one has four pieces:
- A belief: the POV the brand writes from, stated so a competitor could disagree. Not an adjective.
- Vocabulary: the words to reach for and the words banned, by name. “Utilize” out, “use” in.
- Signature moves: the repeatable patterns, like the one-line landing or the question answered in the next sentence.
- Before-and-after examples: the same sentence off-brand and on-brand, so the rule is legible at a glance.
Mailchimp, Shopify Polaris, and Atlassian all do this well: they show the writing, with examples, instead of listing adjectives and hoping. For a deeper look at how distinct brands turn a belief into a recognizable voice, these brand voice examples break several down.
Keep them living, not a PDF nobody opens
The most common reason guidelines fail isn’t that they’re wrong. It’s that they sit in a PDF nobody opens. A guideline only works if it reaches the moment of creation.
A few things help: host it somewhere linkable and searchable instead of a static file; put examples right next to rules so nobody has to interpret; assign an owner who keeps it current; and bake the key rules into the tools your team actually uses, from templates to component libraries. Treat it as a living product, not a one-time deliverable.
Why guidelines matter more in the AI era
Guidelines used to brief humans, who could fill gaps with judgment. Now they also have to brief AI tools, which can’t. When a marketer pastes “confident, friendly, human” into ChatGPT, the model returns the most generic confident-friendly text it knows, which is the same text a competitor’s model returns.
That raises the bar on the parts that were always vaguest, especially voice. Adjectives don’t travel to a model; specific rules and examples do. The guidelines that hold up are the ones precise enough that a person or a tool could apply them cold and still sound like you.
Guidelines that hold up also protect the brand, because consistency is the backbone of brand reputation management across every channel a customer checks.
A pre-launch checklist
Before you call your guidelines done, run them against this:
- Could a new hire produce on-brand work from this alone, without asking you?
- Does every visual rule show a correct and incorrect example?
- Are the exact color values and type scales listed, not just described?
- Does the voice section contain a belief, banned words, and before-and-after examples?
- Is it hosted where people work, with an owner who keeps it current?
If you can answer yes to all five, you have guidelines, not a mood board.
Give your voice the system your logo already has.
The voice section is the one most teams can’t keep consistent once AI tools enter the mix. That’s what Boombrand does: it turns your voice into a machine-readable profile those tools can read.
