<p>Designed by 8 expert designers. Light style features 1px stroke with intricate details, airy design, and generous spacing. Perfect for UI and illustrative elements.</p>

Ultimate Light

**Summary**: 1px hairline stroke, rounded caps and joins, monochrome — the most refined and delicate Ultimate sub-style. Airy open spacing produces a premium, editorial quality that heavier strokes cannot replicate. The tone signals precision without austerity: refined restraint that communicates quality through what is absent rather than what is present. Best for premium SaaS with generous spacing, editorial content-heavy interfaces, and marketing components where elegance is the brand signal; requires careful contrast management and should use Regular or Bold on dark backgrounds below 16px.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 1px (hairline) |
| Fill | None |
| Corner treatment | Rounded caps + rounded joins |
| Color | Monochrome |

### Emotional Scores

Ultimate Light is one of the warmer sub-styles in the catalog — airy open spacing and the absence of heavy geometry reads softly with no cold tension. It is one of the softer sub-styles in the catalog — 1px hairline stroke is among the softest visual weights possible at 24px. It is somewhat friendly — rounded caps lean toward friendly while intricate detail pulls slightly toward refinement. It is near neutral on playfulness leaning slightly warm — detailed without being heavy; not playful, not declarative. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the catalog — rounded joins throughout with no mechanical sharp angles observed.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Plus Jakarta Sans (Light / Regular weight) — rounded humanist, matches the airiness
- **Display**: DM Serif Display — creates elegant editorial contrast with the thin icons
- **Body**: Inter (300–400) — neutral support without competing
- **Avoid**: IBM Plex Mono, heavy grotesque display faces — weight mismatch creates visual incoherence
