The system of visual distinctions, achieved through variations in size, Weight, color, spacing, style, and position — that guides the reader's eye through a composition in order of importance. Typographic hierarchy establishes which elements are primary (headlines), secondary (subheadings), and tertiary (body text, captions, footnotes), creating a scannable structure that communicates the relative significance of content at a glance. Effective hierarchy relies on sufficient contrast between levels: if distinctions are too subtle, the structure collapses and the reader loses orientation.
