This document outlines the contents and purpose of design guidelines. Design guidelines specify how a brand identity can be applied across different situations and media, from print to 3D applications. They define the core brand elements like logos, colors, typefaces, and layouts. Guidelines also demonstrate how brands are realized on various materials and formats, such as business cards, packaging, signage, and digital/video. The level of detail in guidelines depends on the size of the company but generally includes specifications for primary and secondary brand elements.
