Understanding Typography Scales

What is a Typography Scale?

A typography scale creates visual hierarchy through mathematically related font sizes, ensuring consistent and harmonious design across your interface.

How It Works

  • Base Size: The foundation (typically 16px)
  • Ratio: Multiplier between steps (e.g., 1.333 = 33.3% increase)
  • Steps: Number of sizes above/below base size

Units Explained

px:
Fixed pixel values, exact sizes
rem:
Relative to root font size, best for accessibility
em:
Relative to parent element, for component-based designs

Common Ratios

Minor Second (1.067)
Subtle, minimal designs
Perfect Fourth (1.333)
Balanced, traditional designs
Golden Ratio (1.618)
Dramatic, artistic designs

Best Practices

  • Start with a comfortable body text size (16px)
  • Use rem units for better accessibility
  • Test your scale across different screen sizes
  • Consider hierarchy when choosing ratios
