<p>Improved Material Line Icons redrawn using Material Design Guidelines with better coverage and consistency. Fixed where originals fell short.</p>

Outlined Line - Streamline Material

**Summary**: The most neutral Streamline Material sub-style — standard-roundness 1.5–2px stroke on a 24px grid, the direct replacement for Google Material Icons outlined variant, maximum familiarity for Material Design users. The tone signals established convention: "we follow what everyone already recognises." Best as a drop-in replacement for Google Material Symbols Outlined in any Android, web, or cross-platform product using Material Design, where familiarity with Google's icon vocabulary is a feature for the user base.

## Fit & Recommendation

### Primary use cases

- The direct replacement for Google Material Icons outlined variant — use wherever you would use Material Symbols Outlined
- Primary navigation in Android, web, and cross-platform products using Material Design system
- Dense toolbars and action bars where icon neutrality is more important than personality
- Products where Material Design familiarity is a feature for the user base
- Component libraries built on Material 3 needing broader icon coverage than Google provides natively

## Brand & Cultural Identity

### What it communicates

> "We follow established conventions."

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | ~1.5–2px |
| Fill | None |
| Corner treatment | Rounded caps and joins — standard Material-convention roundness |
| Color | Monochrome (black default) |

### Emotional Scores

Material Outlined Line is near neutral on warmth leaning slightly warm — standard-roundness strokes on the 24px grid carry no warmth signal but also no cold tension, sitting at the Material-convention neutral. It is somewhat soft — the 1.5–2px rounded line is moderately soft, neither hairline nor heavy. It is near neutral on friendliness — direct Material alignment reads as universally accessible, landing at an exact neutral between friendly and formal. It is near neutral on playfulness — optimised for recognition rather than expression, producing a genuine neutral. On its human↔mechanical character, it is near neutral leaning slightly warm — rounded caps give a slight human quality while the systematic 24px construction gives a slight mechanical quality, balancing each other.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Roboto — the canonical Material Design typeface; the pairing is a system default
- **Alternative**: Inter — universal humanist neutral; no visual contradiction
- **Display**: Google Sans or DM Sans — for products extending Material conventions with slightly more brand presence
- **Body**: Roboto Regular or Inter Regular
- **Avoid**: Cold geometric sans at heavy weight, serif display fonts, hand-drawn fonts
