What a Style Guide Covers
A style guide documents the rules that keep your brand consistent across every touchpoint — website pages, marketing materials, social media, emails, and print. Without one, each new page or campaign introduces subtle inconsistencies: slightly different blues, varying button styles, inconsistent tone of voice, different heading structures. These compound into a brand that feels amateurish and untrustworthy. A style guide prevents this by giving everyone creating brand assets a single reference to follow.
Visual Style Documentation
Visual style documentation covers: color palette (primary, secondary, neutral colors with hex/RGB/HSL values, usage rules, and accessibility-tested combinations), typography (font families, size scale, weight usage, line height, letter spacing), spacing system (padding/margin scale, layout grid specifications), imagery (photography style, illustration style, icon style, image treatment rules), and component styles (buttons, forms, cards, navigation patterns). Include both ‘do’ and ‘don’t’ examples — showing incorrect usage is as valuable as showing correct. Use the Brand Kit Generator to generate your core visual assets.
Content and Voice Guidelines
Content guidelines define your brand voice: formal or casual, technical or accessible, serious or playful. Document specific rules: whether you use Oxford commas, how you capitalize headings (title case vs sentence case), how you format numbers (1,000 vs 1000), preferred terminology (users vs customers vs members), and words/phrases to avoid. Include writing examples showing the same message in your brand voice vs generic copy. For web content, add SEO guidelines: title tag format, meta description length, heading hierarchy rules, and alt text standards.
Maintaining Your Style Guide
A style guide is a living document. Update it when you add new components, refine your brand, or discover edge cases. Store it where your team can access it easily — a shared document, internal wiki, or dedicated web page. Review quarterly: are teams following it? Are there patterns emerging that the guide doesn’t address? The best style guides are concise enough to actually read (under 20 pages for most brands), specific enough to resolve ambiguity, and accessible enough that new team members can onboard in 30 minutes.
