What is a Brand Guideline?

A brand guideline is a document that provides detailed information about the brand. It highlights the brand values and identities, set out detailed information about the brand identities, set the rule about the composition, design and general use of a brand identity and present examples and templates of marketing collaterals.
The brand guideline is also called the brand book, brand bible or style guide. Andrys (2019) described it as the owner’s manual on how to “use” their brands. It explains how Organisations wants their stakeholders to see their brands. This guide influences both internal and external communications, marketing and advertising. It is an attempt to properly document things about the brand and making it available for different stakeholders that might need it.
