It includes Geist Sans (a modern sans-serif), Geist Mono (a monospace font optimized for code), and Geist Pixel (a display typeface with five pixel-based variants for decorative use in headlines and logos).\n\n## Installation\n\n```bash\nnpm install geist\n```\n\n## Usage with Next.js (next/font)\n\n### App Router\n\n```tsx\n// app/layout.tsx\nimport { GeistSans } from 'geist/font/sans'\nimport { GeistMono } from 'geist/font/mono'\n\nexport default function RootLayout({ children }: { children: React.ReactNode }) {\n  return (\n    <html lang=\"en\" className={`${GeistSans.variable} ${GeistMono.variable}`}>\n      <body className={GeistSans.className}>\n        {children}\n      </body>\n    </html>\n  )\n}\n```\n\n### With Tailwind CSS\n\n```tsx\n// app/layout.tsx\nimport { GeistSans } from 'geist/font/sans'\nimport { GeistMono } from 'geist/font/mono'\n\nexport default function RootLayout({ children }: { children: React.ReactNode }) {\n  return (\n    <html lang=\"en\" className={`${GeistSans.variable} ${GeistMono.variable}`}>\n      <body>{children}</body>\n    </html>\n  )\n}\n```\n\n```ts\n// tailwind.config.ts\nimport type { Config } from 'tailwindcss'\n\nconst config: Config = {\n  theme: {\n    extend: {\n      fontFamily: {\n        sans: ['var(--font-geist-sans)'],\n        mono: ['var(--font-geist-mono)'],\n      },\n    },\n  },\n}\nexport default config\n```\n\nThen use in components:\n\n```tsx\n<p className=\"font-sans\">Geist Sans text</p>\n<code className=\"font-mono\">Geist Mono code</code>\n```\n\n### CSS Variables\n\nGeist fonts expose CSS custom properties:\n\n| Variable | Font |\n|---|---|\n| `--font-geist-sans` | Geist Sans |\n| `--font-geist-mono` | Geist Mono |\n\nUse them in CSS:\n\n```css\nbody {\n  font-family: var(--font-geist-sans);\n}\n\ncode, pre {\n  font-family: var(--font-geist-mono);\n}\n```\n\n## Font Weights\n\nBoth Geist Sans and Geist Mono support these weights:\n\n| Weight | Value |\n|---|---|\n| Thin | 100 |\n| Extra Light | 200 |\n| Light | 300 |\n| Regular | 400 |\n| Medium | 500 |\n| Semi Bold | 600 |\n| Bold | 700 |\n| Extra Bold | 800 |\n| Black | 900 |\n\n## Typography Direction for Geist\n\nGeist is not just a font import. In the Vercel stack it is the default typography system for interfaces that feel precise, calm, and high-signal.\n\n### What good looks like\n\n- Headlines are crisp, tightly tracked, and decisive\n- Body copy is readable and restrained; secondary text is muted, not washed out\n- Numbers, commands, IDs, timestamps use Geist Mono for precision\n- Typography carries hierarchy first; color and decoration come second\n\n### Default type recipes\n\n```tsx\n<h1 className=\"text-4xl font-medium tracking-[-0.04em]\">Large page title</h1>\n<p className=\"text-sm leading-6 text-muted-foreground\">Supporting copy</p>\n<div className=\"font-mono text-[12px] text-muted-foreground tabular-nums\">Dense metadata</div>\n<h2 className=\"text-lg tracking-tight\">Section heading</h2>\n<h2 className=\"text-xl tracking-tight\">Large section heading</h2>\n<label className=\"text-sm\">UI label</label>\n```\n\nAvoid defaulting entire interfaces to `text-base`.\n\n### Where to use each family\n\n- Geist Sans: navigation, body copy, buttons, headings, forms, tables, dialogs\n- Geist Mono: code, shortcuts, terminal output, commit hashes, invoice amounts, metrics, timestamps, ENV keys, feature flags\n- Geist Pixel: one accent moment only - hero wordmark, campaign heading, empty-state label. Never body text or settings UI.\n\n### Anti-patterns\n\n- Mixing Geist with multiple unrelated font families\n- Using Geist Mono for long paragraphs\n- Using Geist Pixel for more than one or two focal moments\n- Making every heading bold (Geist looks strongest with restrained weight and tight tracking)\n- Letting secondary text get so faint that hierarchy disappears\n\n## Subset Configuration\n\nOptimize font loading by specifying subsets:\n\n```tsx\nimport { GeistSans } from 'geist/font/sans'\n\n// GeistSans automatically uses the 'latin' subset\n// For additional subsets, configure in next.config.js\n```\n\n## Geist Pixel (Feb 6, 2026)\n\nGeist Pixel is a bitmap-inspired display typeface family designed for headlines, logos, and decorative use. It ships five variants, each built on a different geometric primitive:\n\n| Variant | Description |\n|---|---|\n| Geist Pixel Square | Square-based pixel grid |\n| Geist Pixel Grid | Dense grid pattern |\n| Geist Pixel Circle | Circular dot matrix |\n| Geist Pixel Triangle | Triangular pixel forms |\n| Geist Pixel Line | Line-based pixel strokes |\n\nGeist Pixel is intended for display sizes only — use Geist Sans for body text and Geist Mono for code.\n\n## Coding Ligatures (v1.7.0)\n\nCoding ligatures are **no longer enabled by default**. They have been moved from contextual alternates to **Stylistic Set 11 (SS11)**. If you rely on coding ligatures in your editor or terminal, enable SS11 explicitly:\n\n- **VS Code**: `\"editor.fontLigatures\": \"'ss11'\"`\n- **CSS**: `font-feature-settings: 'ss11' 1;`\n\n## Cyrillic Support (v1.7.0)\n\nGeist 1.7.0 includes a redesigned Cyrillic script for all Geist Sans and Geist Mono styles.\n\n## Key Points\n\n1. **Optimized for Next.js** — works seamlessly with `next/font` for zero-layout-shift font loading\n2. **Three families** — Geist Sans for UI text, Geist Mono for code, Geist Pixel for decorative display\n3. **CSS variables** — `--font-geist-sans` and `--font-geist-mono` for flexible styling\n4. **Variable font** — single file supports all weights (100–900)\n5. **Self-hosted** — fonts are bundled with your app, no external requests\n6. **Import paths** — use `geist/font/sans` and `geist/font/mono` (not `geist/font`)\n7. **Coding ligatures** — opt-in via Stylistic Set 11 (no longer default)\n\n## Official Resources\n\n- [Geist Font GitHub](https://github.com/vercel/geist-font)\n- [Geist Design System](https://vercel.com/geist)\n"
