Brand guidelines, also known as brand standards or brand style guides, are a set of rules and standards that dictate how a brand should be presented and represented across various media. They outline the visual, verbal, and experiential elements of a brand, including its logo, colours, typography, imagery, tone of voice, and messaging.

The purpose of brand guidelines is to ensure consistency and coherence in the way a brand communicates and presents itself, regardless of the medium or platform. By adhering to these guidelines, a brand can create a strong and unified identity that is easily recognisable and memorable to its audience.

Brand guidelines may include specific instructions on how to use a brand's logo and colour palette, guidelines for creating marketing materials such as brochures, flyers, and websites, and recommendations for social media and other digital platforms. They may also include information on the brand's target audience, brand values, and tone of voice.

Overall, brand guidelines help maintain a brand's integrity and strengthen its position in the market by providing a clear and consistent representation of the brand to its audience.
