Typography is fundamental to good user experience. The right balance of line length, font size, and line height creates a comfortable reading environment that reduces eye strain and improves comprehension.

When lines are too long, readers struggle to track from the end of one line to the beginning of the next. When lines are too short, the eye has to travel back too frequently, breaking the reading rhythm. The sweet spot is typically between 45-75 characters per line.

Too Narrow

When text lines are too narrow, the reading experience becomes choppy and interrupted. The eye has to jump to a new line too frequently.

Optimal

The ideal line length (45-75 characters) provides comfortable reading without requiring excessive eye movement or causing fatigue.

Too Wide

When lines are too wide, it becomes difficult to track from the end of one line to the beginning of the next, causing readers to lose their place.

Readability Tips

  • Aim for 45-75 characters per line for body text
  • Use 1.5-1.7 line height for optimal readability
  • Increase line height for wider text blocks
  • Consider larger font sizes for longer reading sessions
  • Test your typography with real content, not lorem ipsum
