Narrow No-Break Space (U+202F) | Keep Your Text Together

The narrow no-break space (U+202F) is used for non-breaking spacing in compact layouts. Learn how it works.

What Is Narrow No-Break Space?

The Narrow No-Break Space (U+202F) is a specialized Unicode character that combines two key properties:

  • Narrow width (narrower than standard no-break space)
  • Non-breaking behavior (prevents unwanted line breaks)

Key Features

  • Width: Approximately 3/18 of an em (between thin space and regular space)
  • Non-collapsing in HTML (preserves spacing)
  • Used primarily for linguistic and typographic precision

Comparison With Similar Spaces

Character Unicode Width Breaking Primary Use
Narrow No-Break U+202F ~3/18 em No French typography, units
No-Break Space U+00A0 1 em No General non-breaking
Thin Space U+2009 1/6 em Yes Small separation
Medium Space U+205F 4/18 em Yes Mathematical expressions

Technical Considerations

Font Support

  • Well-supported in modern fonts
  • Falls back to standard space in older systems
  • Test with fonts like Cambria, Times New Roman

Accessibility

  • Screen readers typically ignore
  • Doesn’t affect text-to-speech parsing
  • Preferred over multiple regular spaces

Best Practices

? Use for linguistic precision in French/Russian
? Excellent for unit/value pairs (100 km)
? Perfect for citation formatting (Art. 123)
? Avoid in general text (use regular spaces)
? Don’t use for visual alignment (use CSS instead)

Common Problems Fix

Why isn’t my narrow no-break space working?
Check:

  1. Font support (try different fonts)
  2. Character encoding (ensure UTF-8)
  3. Application limitations (some web apps may strip)

How to convert existing spaces?

javascript

// Convert regular spaces before units
text.replace(/(\d)\s([km€])/g, '$1\u202F$2');
