<p>Micro is built on a tiny 10px grid, perfect for interfaces. The Line variant offers minimal, clean strokes for small icon sizes.</p>

Micro Line

**Summary**: The default Micro sub-style — 1px rounded stroke on a 10px grid, engineered for maximum legibility at minimum size, designed to behave like punctuation alongside small text. Rounded terminals prevent sharp angle merging at high pixel density; stripped-back construction means every design decision serves legibility, not expression. The tone signals invisible infrastructure: "we are here if you look; we won't demand that you do." Best for inline actions within body text, secondary actions in dense data tables, overflow menus, tooltips, status indicators in constrained-width components, and any context where the goal is recognisable at minimum footprint rather than visually expressive.

## Fit & Recommendation

### Primary use cases

- Inline icons within body text or dense label copy where icon height must match type cap-height (10–14px)
- Secondary actions in dense data tables — icons that must be present but should not draw attention
- Overflow menus and contextual action lists at compact display density
- Tooltips and hint labels where icons appear alongside very small text
- Status indicators within constrained-width components (table cells, tag chips, breadcrumbs)
- Any context where the goal is "recognisable at minimum footprint," not "visually expressive"

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 1px |
| Fill | None |
| Corner treatment | Rounded caps and joins — simplified vs other families; prevents sharp angle merging at small sizes |
| Color | Monochrome |

### Emotional Scores

Micro Line is somewhat mechanical on warmth — simplified construction strips any warmth from the rounded caps, leaving a functional and neutral-to-cool register. It is near neutral on softness leaning slightly soft — 1px rounded strokes are soft in weight, though stripped-back construction reads as direct rather than soft. It is somewhat formal — purpose-driven simplification communicates function over feeling; not unfriendly, but not warm. It is one of the more serious sub-styles in the catalog — every design decision serves legibility, not expression, and the 10px constraint makes seriousness of purpose literal. On its human↔mechanical character, it is somewhat mechanical — simplified geometric construction with no expressive elements means utility focus reads as systematic.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter at 11–12px — both systems are engineered for screen legibility at small sizes; the pairing is almost a design tautology
- **Alternative**: IBM Plex Sans — screen-optimised, slightly more structured; appropriate in developer tool and data product contexts
- **System fallback**: -apple-system / system-ui — appropriate in contexts where Micro Line appears as OS-adjacent UI chrome
- **Avoid**: Any display or editorial typeface, any font with strong personality at small sizes
