A manual that contains standards for the design and writing of documents.

• A. Style guide / corporate style guide
• B. Branding manual
• C. Typography handbook
• D. Editorial guide

Answer: (A)

A style guide is the go-to manual for both how documents are written and how they are presented. It provides rules for language use—such as tone, grammar, punctuation, capitalization, and spelling—and also sets the standards for document design, including typography, heading structures, margins, spacing, and overall layout. That combination ensures every document from the organization reads consistently and looks cohesive, no matter who produced it.

A branding manual focuses mainly on visual identity like logos, color palettes, and overall brand imagery. A typography handbook zeros in on font choices and how type should be used. An editorial guide concentrates on editorial style rules, but it typically doesn’t govern the full design of documents.
