Web Typography
Select fonts, type pairings, and icon libraries for web apps through a structured decision workflow.
Decision Workflow
Step 1: Identify app type
Ask or infer from context:
| App Type | Typography Priority |
|---|
| SaaS / Dashboard | Data density, numeric clarity, readability at small sizes |
| Marketing / Landing | Visual impact, personality, clear heading/body hierarchy |
| Documentation | Long-form readability, code block integration |
| E-commerce | Scannability, trust, premium feel for campaigns |
| Portfolio / Creative | Personality, visual distinction, memorable type |
| Corporate / Enterprise | Professionalism, trust, accessibility |
Step 2: Determine brand tone
- Neutral/Professional → Inter, Geist, Source Sans 3
- Friendly/Modern → DM Sans, Plus Jakarta Sans, Manrope
- Premium/Editorial → Serif headings (Playfair Display, Instrument Serif) + sans body
- Technical/Developer → Geist, Space Grotesk, JetBrains Mono for code
- Playful/Creative → Cabinet Grotesk, Syne, Epilogue
Step 3: Pick from quick-start combos
| App Type | Heading | Body | Icons | When to use |
|---|
| SaaS (safe default) | Inter 600 | Inter 400 | Lucide | Proven, neutral, works everywhere |
| SaaS (modern) | Geist 600 | Geist 400 | Lucide | Next.js ecosystem, web-native feel |
| SaaS (friendly) | Plus Jakarta Sans | DM Sans | Phosphor | Startup, product-led growth |
| Marketing | Playfair Display | Inter | Lucide | Premium, authoritative |
| Marketing (bold) | Bebas Neue | Open Sans | Remix | High-impact hero sections |
| Docs | Inter 600 | Inter 400 + Fira Code | Lucide | Industry standard (Tailwind, Vercel) |
| E-commerce | Playfair Display | Montserrat | Phosphor | Luxury/fashion/lifestyle |
| Portfolio | Syne | Satoshi | Phosphor | Tech-creative studios |
| Corporate | Source Sans 3 | Source Sans 3 | Lucide | Mature, trustworthy, wide language support |
For deeper exploration of all available fonts and pairings, read references/font-catalog.md.
Step 4: Select icon library
| Need | Library | Why |
|---|
| General purpose (default) | Lucide (1,600+ icons) | Best balance: count, consistency, tree-shaking, community |
| Weight variation / design system | Phosphor (1,500+ base, 6 weights) | Map icon weight to typography weight systematically |
| Maximum coverage | Tabler (6,000+ icons) | Largest free MIT set, good for complex admin UIs |
| Tailwind ecosystem | Heroicons (292 icons, 4 styles) | Small but impeccable, by Tailwind Labs |
Match icon stroke to font weight: Regular (400) text pairs with 1.5-2px stroke icons (Lucide default, Phosphor Regular). Bold (600-700) text pairs with filled/solid icons.
For full comparison of all libraries, read references/icon-catalog.md.
Step 5: Implement type scale
Use Major Third (1.250) as default ratio. Adjust for app type:
| Ratio | Name | Best for |
|---|
| 1.125 | Major Second | Dense dashboards, admin panels |
| 1.200 | Minor Third | Compact apps, data-rich interfaces |
| 1.250 | Major Third | Most web apps (recommended default) |
| 1.333 | Perfect Fourth | Marketing sites, editorial |
CSS custom properties with fluid sizing
:root {
--fs-xs: clamp(0.64rem, 0.6rem + 0.15vw, 0.7rem);
--fs-sm: clamp(0.8rem, 0.77rem + 0.15vw, 0.875rem);
--fs-base: clamp(1rem, 0.95rem + 0.25vw, 1.125rem);
--fs-lg: clamp(1.125rem, 1rem + 0.5vw, 1.25rem);
--fs-xl: clamp(1.35rem, 1.15rem + 0.85vw, 1.563rem);
--fs-2xl: clamp(1.6rem, 1.3rem + 1.2vw, 1.953rem);
--fs-3xl: clamp(1.95rem, 1.5rem + 1.75vw, 2.441rem);
--fs-4xl: clamp(2.4rem, 1.75rem + 2.5vw, 3.052rem);
--lh-tight: 1.1;
--lh-snug: 1.25;
--lh-normal: 1.5;
--lh-relaxed: 1.65;
--ls-tight: -0.025em;
--ls-wide: 0.025em;
}
Step 6: Font loading
- WOFF2 only — 97%+ support, best compression
- Self-host or Fontsource —
npm install @fontsource-variable/inter
font-display: swap for body, optional for display headings- Preload 1-2 critical files —
<link rel="preload" href="/fonts/inter-variable.woff2" as="font" type="font/woff2" crossorigin>
- Variable fonts over multiple static files
- Subset to Latin + Latin Extended-A for 90%+ size reduction
@font-face {
font-family: 'Inter';
src: url('/fonts/inter-variable.woff2') format('woff2');
font-weight: 100 900;
font-display: swap;
}
Fallback stack: 'Inter', ui-sans-serif, system-ui, -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif;
Step 7: Icon implementation
Default pattern — npm with tree-shaking:
import { Home, Settings, User } from 'lucide-react';
<Home size={20} strokeWidth={1.5} />
For prototypes/landing pages, CDN is fine:
<script src="https://unpkg.com/lucide@latest"></script>
<script>lucide.createIcons();</script>
