Starting a brand style guide for a startup I just joined. Never built one from zero before. What sections are essential and what order do you tackle them in? Don’t want to overthink it but also don’t want gaps.
Start with the brand’s core elements before anything visual. Mission statement, values, brand personality, and tone of voice. A lot of designers skip straight to colors and logos, but without the strategic foundation the visual decisions feel arbitrary. Once you have those, move into logo usage rules (clear space, minimum sizes, what not to do), then color palette with specific hex/RGB/CMYK values, then typography hierarchy. After the visual core, add photography and illustration style guidance, and iconography if relevant. The last section should be application examples showing everything together on business cards, social templates, email headers. Those real-world examples are what make a style guide actually usable rather than just a pretty PDF nobody references.
I’ve built probably 40+ brand guides across different industries and the structure @Willowdusk described is solid. I’d add a few things from experience though.
Include a ‘don’t do this’ section for every major element. Show the logo stretched, recolored wrong, placed on busy backgrounds. People learn faster from bad examples than good ones. My clients reference those pages more than anything else in the guide.
For the color section, don’t just list primary and secondary palettes. Show color application ratios. Something like ‘60% white, 30% primary blue, 10% accent orange’ gives people an actual formula instead of hoping they figure out the right balance on their own.
Typography needs more than just ‘use this font.’ Specify sizes, weights, and line heights for every use case: H1 through body text, captions, pull quotes. If you’re working across print and digital, include both sets of specs because the optimal sizes are different.
One more thing: version your guide. Put a date and version number on it. Brands evolve and people need to know they’re referencing the latest version, not something from two years ago that’s been floating around on someone’s desktop.
biggest mistake I see in style guides is making them too rigid. Leave room for creative interpretation. The best guides set guardrails without being a straitjacket. If designers feel like they can’t breathe within the system, they’ll just ignore it.
Here’s the structure I use for every brand style guide. It’s evolved over years of trial and error and client feedback, and it works for startups through mid-size companies.
Section 1: Brand Overview. This is your ‘why.’ Brief brand story, mission, vision, core values, and brand personality traits (pick 3-5 adjectives). Keep this to one or two pages. Nobody reads a ten-page brand manifesto.
Section 2: Logo System. Primary logo, secondary/alternate versions, monochrome versions, minimum size requirements, clear space rules, and a full page of incorrect usage examples. @w.moses.flint.54 is right that the ‘don’t do this’ examples are gold.
Section 3: Color Palette. Primary colors (2-3), secondary colors (2-4), neutral colors (2-3). Include hex, RGB, CMYK, and Pantone values. Show accessible color pairings with contrast ratios. Include the application ratio breakdown.
Section 4: Typography. Primary typeface for headlines, secondary for body, and a system/web-safe fallback. Include a full type scale with sizes, weights, line heights, and letter spacing for both digital and print. Show hierarchy examples in actual layouts.
Section 5: Photography and Imagery. This is the section most people skip but it makes the biggest difference in brand consistency. Define the photo style (candid vs posed, color treatment, subjects, what to avoid). Include mood board examples.
Section 6: Iconography and Graphics. If the brand uses icons, define the style (line weight, corner radius, grid system). Same for any graphic elements, patterns, or textures.
Section 7: Voice and Tone. Even if you’re a designer, include this. Write three to five example sentences in the brand voice. Show the same message written ‘on brand’ and ‘off brand.’ Include a word list of terms to use and avoid.
Section 8: Applications. Show everything together on real deliverables: business cards, letterhead, social media posts, email signatures, presentation slides, website screenshots. This is what makes the guide practical.
For format, I deliver as a PDF and as a Figma file. The Figma version lets teams copy assets directly. Start simple, iterate, and version it like @w.moses.flint.54 said.
This is incredibly helpful, thanks everyone. @Smoke_Canyon that structure is exactly the framework I needed. Going to start with the brand overview this week and work through the sections in order. The Figma delivery idea is great too.
One thing I’d add to what @Smoke_Canyon laid out: consider your audience for the guide. If it’s just for the design team, you can be more technical with specs. But if marketing, sales, or external partners will use it, you need to simplify the language and add more visual examples.
I’ve started creating two versions for larger clients. A comprehensive internal version with all the technical specs, Figma components, and detailed rationale. And a condensed external version that focuses on do’s and don’ts with lots of visuals and minimal text. The external version is usually 12-15 pages max while the internal one can run 40+.
Also, build the guide in a format that’s easy to update. I’ve seen too many beautiful style guides created in InDesign that nobody ever updates because it’s a hassle to open the file, export a new PDF, and redistribute it. A Notion page or a dedicated section in your design system documentation stays current because updating it takes seconds rather than a production cycle. The best style guide is the one that actually gets maintained.
