Typography Fundamentals Guide
Understanding Font Pairing
Effective font pairing creates visual hierarchy and improves readability. Here are the key principles:
Font Categories Explained
- Sans-serif: Clean, modern, excellent for screens (Inter, Roboto, Open Sans)
- Serif: Traditional, formal, great for print and long-form content (Merriweather, Playfair Display)
- Display: Decorative, attention-grabbing, best for headlines (Montserrat, Poppins)
- Monospace: Technical, coding, fixed-width (Roboto Mono, Courier New)
Typography Best Practices
Follow these guidelines for optimal typography:
Readability Metrics
Optimal typography settings for web content:
- Line Height: 1.5-1.8 for body text (improves readability)
- Font Size: 16-20px for body text (accessible on all devices)
- Line Length: 50-75 characters per line (optimal reading speed)
- Letter Spacing: 0-0.5px for body, 1-2px for headings (improves legibility)
- Contrast Ratio: Minimum 4.5:1 for normal text (WCAG AA compliance)

Frequently Asked Questions
For most websites, 2-3 fonts are sufficient:
- Primary Font: For headings and important text
- Secondary Font: For body text and paragraphs
- Optional Accent Font: For special elements like quotes or buttons
Using too many fonts can create visual clutter and slow down your website. Stick to a consistent typography system.
Font Weight: Refers to the thickness of the characters, measured on a scale (100-900). Common weights:
- 300: Light
- 400: Regular/Normal
- 500: Medium
- 600: Semi-bold
- 700: Bold
- 800: Extra-bold
- 900: Black
Font Style: Refers to the italic or oblique version of a font. Some fonts have true italics with different character shapes, while others simply slant the regular version.
Follow these principles for successful font pairing:
- Contrast: Pair a serif with a sans-serif, or a bold font with a light one
- Similarity: Choose fonts with similar x-heights or proportions
- Hierarchy: Use font weights and sizes to create clear visual hierarchy
- Mood: Ensure fonts match the tone and purpose of your website
- Readability: Test combinations with actual content
This tool helps you test combinations in real-time to find the perfect match.
Google Fonts are optimized for performance, but there are best practices to follow:
- Limit Font Files: Only load the weights and styles you actually use
- Use font-display: swap: Prevents invisible text during loading
- Preconnect to Google Fonts: Add to your HTML head
- Combine Requests: Load multiple fonts in a single request
- Self-host if needed: For maximum control and privacy
This tool generates optimized CSS code with performance best practices included.
Web Typography Best Practices
Accessibility Considerations
- Minimum Font Size: 16px for body text to ensure readability
- Contrast Ratio: 4.5:1 for normal text, 3:1 for large text (WCAG AA)
- Responsive Typography: Use relative units (rem, em) for font sizes
- Line Length: 50-75 characters per line for optimal reading
- No Pure Text Images: Use actual text instead of text in images
Performance Optimization
- Font Loading Strategy: Use font-display: swap for better perceived performance
- Subset Fonts: Only include characters you actually use
- Preload Critical Fonts: Load above-the-fold fonts first
- Cache Fonts: Leverage browser caching for returning visitors
- Modern Formats: Use WOFF2 format for better compression
Cross-Browser Compatibility
- Font Stack Fallbacks: Always provide fallback fonts in your CSS
- Test on Different Browsers: Font rendering can vary between browsers
- Check Web-safe Alternatives: Include system fonts as fallbacks
- Monitor Font Loading: Use browser developer tools to check font loading
- Consider Variable Fonts: Single file containing multiple weights/styles
Pro Tip: Variable Fonts
Consider using variable fonts for better performance and flexibility:
- Single file contains all weights and styles
- Smaller total file size compared to multiple font files
- Fine control over weight, width, and other axes
- Better performance with fewer HTTP requests
- Future-proof approach to web typography
