Visual hierarchy scaling

Visual hierarchy adapts significantly when interfaces transition between different screen sizes and contexts. Understanding these changes helps maintain clear content relationships while optimizing for each platform's strengths.

Key hierarchy transitions:

• watchOS: Emphasizes instant recognition through strong contrast and size differences. Time-sensitive information dominates the display while secondary elements remain minimal or hidden, supporting quick glances and immediate comprehension.
• iPhone to iPad evolution: Content expands from single-column to multi-pane layouts. Mail demonstrates this through a two-column split view where message list and content live side-by-side, maintaining clear visual connection while maximizing screen space.

Focus on content relationships that must scale coherently. Primary actions should maintain prominence while supporting content adapts to available space. Test how hierarchies translate between compact and expanded states to ensure clear visual flow.
