Target Size and Spacing

Target Size and Spacing turns a frequent interface judgment into an executable constraint before generation.

Design Principle

Interactive targets need enough size and spacing, especially on mobile, toolbars, and dense lists.

Principle

Interactive targets need enough size and spacing, especially on mobile, toolbars, and dense lists.

Design action

Default touch targets to roughly 44px or equivalent padding; dense desktop controls still need clear hover/focus and spacing.

Examples

Positive example: Icon buttons, table row actions, mobile bottom bars, and dense filters need low mis-tap risk. Counterexample: A 16px icon has no extra hit area.

Apply when

Icon buttons, table row actions, mobile bottom bars, and dense filters need low mis-tap risk. Users need to judge state, scope, risk, or next action quickly.
