Sentence Case vs Title Case: When to Use Each

The Two Main Capitalization Styles

When writing headings, article titles, and UI labels, two styles dominate: Sentence case and Title Case.

  • Sentence case: Only the first word and proper nouns are capitalized

  • Title Case: Most words are capitalized (excluding short prepositions, articles, conjunctions)

The Modern Trend

The tech industry has shifted toward sentence case for UI components because:

1. It's more conversational and approachable

2. It requires fewer decisions (no need to remember which words to capitalize)

3. It scales better internationally (some languages don't capitalize nouns the same way)
