<p>Material Pro Rounded Line variant features rounded corner styles in line format, following Google's Material Design with enhanced coverage and consistency.</p>

Rounded Line - Streamline Material

**Summary**: Streamline Material's warmer line variant — explicitly wider corner radii and pill-like stroke caps on a 24px grid, the same icon vocabulary as Outlined Line but with deliberate added approachability for consumer and mobile-first products. The pill-like caps and generous corner radii give warmth characteristic of humanist design within the Material system. The tone signals "we follow conventions, and we made them warmer for you." Best for consumer-facing Material products, mobile-first and touch interfaces, health and lifestyle apps operating within a Material-adjacent system, and products targeting broad audiences where the extra roundness reduces any perceived coldness.

### Emotional Scores

Material Rounded Line is one of the friendlier sub-styles in the catalog within the Material family — explicitly wider corner radii and pill-like caps introduce warmth beyond the Outlined standard. It is one of the softer sub-styles in the catalog within the Material family — the additional rounding compounds the softness of the line weight, making it clearly soft. It is one of the friendlier sub-styles in the Material family — the extra roundness tips clearly toward friendly, with the consumer register more visible than in Outlined. It is somewhat warm on playfulness — softer geometry reads as slightly more casual than Outlined without being playful or serious. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the Material family — pill-like caps and generous corner radii give the warmth characteristic of humanist design.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Plus Jakarta Sans — humanist warmth that echoes the additional roundness of this variant
- **Alternative**: Nunito — explicitly rounded terminals; may be too warm for some Material contexts
- **Display**: DM Sans — modern humanist with warmth
- **Body**: Inter Regular or Plus Jakarta Sans Regular
- **Avoid**: Cold geometric or monospace fonts — personality mismatch with the warmer geometry
