Icon System Consistency Across Products
Grid, stroke, and metaphor rules that keep UI recognizable at small sizes.
Nestlancer Editorial

Inconsistent icons make products feel like unrelated apps. A shared icon system defines grid, stroke, metaphor, and corner style.
Grid and stroke
- 24×24 dp base grid with 2px stroke common for Lucide-style
- Optical alignment: play and triangle icons often need visual centering tweaks
Metaphor rules
Document approved metaphors:
| Concept | Icon choice |
|---|---|
| Settings | Gear, not wrench unless maintenance |
| Delete | Trash with confirm elsewhere |
| Export | Upload arrow out of box |
Product line consistency
Marketing site, web app, and mobile share library—custom one-offs need system council approval.
Small size legibility
Test at 16px—over-detailed icons muddy. Simplify or use filled variant.
Icon systems are micro-brand—consistency signals one trustworthy product family.
