PostEaseThe short answer
A brand guideline is a document covering a business's visual identity: logo usage and clear space, an approved color palette, typography, photography or imagery style. It is a close cousin of a social media style guide, which covers voice and writing, rather than the same document. Most businesses need both, even though the two are often confused for one another.
What needs to be in a basic one
A useful starting brand guideline is short. Most of the value comes from a few core fields:
- The logo's correct usage and minimum clear space, plus what not to do to it
- An approved color palette, with exact values (hex codes), not just names
- A typography choice for headlines and body text
- A few real examples of on-brand imagery, and what to avoid
Why it matters once more than one person creates visual content
A single person designing their own graphics rarely needs a formal guideline. The visual identity lives in their own habits. Once a second person, a freelancer, or an agency is producing visual content, a written guideline is what keeps the identity recognizable across everyone touching it, rather than drifting toward whatever look each new contributor happens to prefer.
