Typography & Font Pairing for Nuxt Apps

Typography sets the tone of your application before a single word is read. The right font pairing communicates professionalism, friendliness, or creativity - the wrong one creates visual noise.

Nuxt UI v4 uses CSS variables for font families, making it straightforward to apply custom typography to your entire application.

How Fonts Work in Nuxt UI

Nuxt UI references these CSS variables for typography:

:root {
  --font-sans: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}

Every Nuxt UI component that renders text uses --font-sans. Code blocks and monospace elements use --font-mono.

Override these variables to change the typeface globally - no need to modify individual components.

Choosing a Font Strategy

Option 1: System Fonts (Fastest)

Zero network requests, zero layout shift:

:root {
  --font-sans: ui-sans-serif, system-ui, -apple-system, sans-serif;
  --font-mono: ui-monospace, "SF Mono", monospace;
}

Best for: performance-critical apps, utility tools, dashboards.

Option 2: Single Web Font (Balanced)

One font family with variable weight:

:root {
  --font-sans: "Inter", ui-sans-serif, system-ui, sans-serif;
}

Best for: most applications. Inter, DM Sans, or Geist are safe choices.

Option 3: Font Pair (Expressive)

Distinct heading and body fonts:

:root {
  --font-sans: "DM Sans", ui-sans-serif, sans-serif;
  --font-heading: "Space Grotesk", ui-sans-serif, sans-serif;
}

Best for: marketing sites, branded experiences, content-heavy pages.

Loading Fonts in Nuxt

Nuxt Fonts (@nuxt/fonts) auto-detects and optimizes font loading. Define your fonts in nuxt.config.ts:

export default defineNuxtConfig({
  fonts: {
    families: [
      { name: "Inter", provider: "google", global: true },
      { name: "JetBrains Mono", provider: "google", global: true },
    ],
  },
});

Then reference them in your CSS:

:root {
  --font-sans: "Inter", ui-sans-serif, system-ui, sans-serif;
  --font-mono: "JetBrains Mono", ui-monospace, monospace;
}

Typography Best Practices

Line Height

Context	Line Height	Example
Headings	1.1–1.3	`leading-tight`
Body text	1.5–1.75	`leading-relaxed`
UI labels	1.25	`leading-snug`

Font Size Scale

Stick to a consistent type scale. Tailwind's default scale works well:

Element	Size	Class
Display heading	48px	`text-5xl`
Page heading	30px	`text-3xl`
Section heading	24px	`text-2xl`
Subheading	20px	`text-xl`
Body	16px	`text-base`
Small / caption	14px	`text-sm`
Tiny / label	12px	`text-xs`

Font Weight Usage

Weight	Purpose
400 (regular)	Body text
500 (medium)	Labels, nav items
600 (semibold)	Subheadings, button text
700 (bold)	Headings, emphasis
