## What it does

The skill defines a typographic system for an interface: a size scale from caption to display, a weight set, line-height values and letter spacing. Sizes derive from a 16px base through a ratio, such as 1.25 or 1.333.

Inside you get the scale components spelled out: sizes from 12px up to 48–64px, weights from Regular to Bold, Tight 1.2 for headings and Normal 1.5 for body text, tracking for large headings and uppercase labels. Font pairing and mobile adaptation are covered too.

It is not for judging a screen you already shipped — that is `critique-typography`, and line length belongs to `readable-measure`. Reach for this one when the type system needs designing up front rather than patching later.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill typography-scale -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/typography-scale/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/typography-scale/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill typography-scale -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/typography-scale/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill typography-scale -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/typography-scale/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Owl-Listener/designer-skills typography-scale
```

2. **Manually: put the files in place**
- File: `.github/skills/typography-scale/SKILL.md`

### Gemini CLI

```bash
npx skills add Owl-Listener/designer-skills --skill typography-scale -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Owl-Listener/designer-skills --path ui-design/skills/typography-scale
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/typography-scale/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Owl-Listener/designer-skills --skill typography-scale -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- derive a size scale from a 16px base using a ratio
- pick weights and line heights for headings and body copy
- pair a primary, secondary and mono typeface
- carry the scale to mobile without hurting readability
- document usage rules for every style

## Example prompts
- build a modular type scale for a landing page on a 1.25 ratio
- set weights and line heights for headings and body text
- adapt the scale to mobile, keeping body at 16px or larger

# Typography Scale
You are an expert in typographic systems for digital interfaces.
## What You Do
You create modular typography scales that ensure readable, harmonious, and consistent text across a product.
## Scale Components
### Size Scale
Based on a ratio (e.g., 1.25 major third, 1.333 perfect fourth):
- Caption: 12px
- Body small: 14px
- Body: 16px (base)
- Subheading: 20px
- Heading 3: 24px
- Heading 2: 32px
- Heading 1: 40px
- Display: 48-64px
### Weight Scale
Regular (400), Medium (500), Semibold (600), Bold (700).
### Line Height
- Tight: 1.2 (headings)
- Normal: 1.5 (body text)
- Relaxed: 1.75 (long-form reading)
### Letter Spacing
- Tight: -0.02em (large headings)
- Normal: 0 (body)
- Wide: 0.05em (uppercase labels, captions)
## Font Pairing
- Primary: UI and body text
- Secondary: headings or editorial (optional)
- Mono: code, data, technical content
## Responsive Typography
- Scale down heading sizes on mobile
- Maintain body size (16px minimum for readability)
- Adjust line lengths (45-75 characters optimal)
## Best Practices
- Use a mathematical ratio for harmony
- Limit to 4-5 sizes in regular use
- Ensure body text is minimum 16px
- Test with real content, not lorem ipsum
- Document usage rules for each style
```
