Style Guide: How To Write One for Your Brand

Updated June 7, 2022

A style guide isn’t the most exciting content to create, but it’s one of the most essential for the success of your content. It can provide clear, universal guidance to thwart brand fails that come from inconsistency or miscommunication among your content team.

A style guide also can be a way to foster content authenticity – containing instructions for all parties creating content for your company.

This article addresses why your organization needs a style guide, details what to include in your style guide, and gives examples of top-notch style guides to ensure streamlined external communications.

Why you need a style guide

First, what is a brand style guide?

A brand style guide is a holistic set of standards that defines your company’s branding. It references grammar, tone, logo usage, colors, visuals, word usage, point of view, and more.

By creating a detailed brand style guide, you ensure the published content is consistent, polished, recognizable, and more enjoyable. A thorough, well-thought style guide puts your audience first. It creates a recognizable, engaging voice and personality with which readers can form a more personal connection.

What to include in your style guide

GatherContent recommends that a style guide be between four and five pages. Anything longer is too much to digest. Create a style guide based on what resonates with who your audience is and what they want.

If you have a mission statement or boilerplate about us description for your brand, start there. Revisit it to make sure it’s not only on point with what it says but how it says it. If you define your brand voice as conversational, but your mission statement is filled with corporate jargon, it’s probably worth revisiting.

From there, create a table of contents for your style guide and use it as an outline. All style guides should include an introduction. This might include a mission statement, letter from the CEO, about us page, or general overview of the company’s brand and audience. Next, create a section on how your brand talks and writes and another section on branded visuals. Here’s a breakdown of what these sections should include.

Writing section

A brand’s image often can be attributed to what it says and how it says it. Details like whether to use “&” or “and” or the numerical or written versions of numbers may seem trivial. But the sum of these details adds up. If they are consistent throughout your brand’s published work, they convey the same voice, coherent thinking, and credibility impossible to attain without this consistency.

Here are some tips for ensuring that your brand guide aids in creating first-rate content:

  • Baseline guide: Use an existing style guide (like AP Style) as the base. Add your brand’s differences, such as the use of the Oxford comma or general best practices for emojis.
  • Formatting: Add a small section around formatting. Include details on how to use bullets, lists, hyphens, and quotes.
  • Tone and voice: Describe these qualities and give examples of right and/or wrong tone and voice. If you want a playful tone, explain what that means. This section also should include information on sentence structure. Do you want long, complex sentence structures, a mix, or Hemingway simplicity? (Pro tip: Don’t use long sentences if you want to be persuasive.)
  • Additional details: Include a section on how to engage, words to avoid, and any other details important to your brand. Use the brand personality spectrum below to get a better idea of what’s important to your brand’s written content.

Visual section

Visual cues are as important to brand consistency as the written aspects. Consider these elements for your style guide’s visual section:

  • Formats: Include information on how to stay on brand with other formats of content, including infographics, video, motion graphics, etc.
  • Colors: Detail your brand’s palette of colors, including function. Make sure to include each color’s hex, CMYK, and RGB codes, as well as Pantone number.
  • Logo: Include all versions of your logo and examples of proper uses. If you have older or frequently misused versions, include them as “don’t-use” examples.
  • Fonts: List all brand fonts for headings, paragraphs, etc., and their uses.
  • Presentation format: Include a link to a company slideshow template for presentations.

Though Uber recently moved its style guide to a protected site, its former publicly shared guide is a helpful example. It’s packed with GIFs and videos that convey the very movement Uber is so proud of. Uber uses this site to not only describe brand style but to share the brand story, showcase examples of its branding done well, and provide helpful tools. (The image below with the big, bold text reflects Uber’s style – “A bold new brand awaits.”

According to Uber, the guidelines cover nine elements: logo, color, composition, iconography, illustration, motion, photography, tone of voice, and typography. The style guide’s home page also makes it convenient for users by highlighting and linking the most frequently requested assets:
