closure

What problem does it solve?

Closure helps designers ensure that implied, partially drawn shapes (icons, logos, cards, and diagrams) are perceived as complete and intentional rather than broken, confusing, or ambiguous.

Core Features & Use Cases

• Design icons with implied shapes: Use partial outlines or strategic gaps so the user’s perception completes the form (especially at small sizes).
• Create logos using negative space: Communicate recognizable marks through implied contours (e.g., hidden shapes in gaps).
• Imply containment in layouts: Make cards and containers feel distinct without heavy borders by relying on subtle cues (shadow/tint/spacing).
• Troubleshoot closure failure: Detect when gaps are too large, the suggestion is too subtle, or the user audience can’t complete the form.

Quick Start

Apply the closure heuristic to your design by checking whether the implied form is recognizable at the actual size and whether users can complete it without guessing.
