What is Sentence Case?
Sentence case (also called down style or sentence style) is the conventional capitalization standard used in English prose. In sentence case, only the first word of a sentence is capitalized, along with proper nouns and the standalone pronoun "I". All other words remain in lowercase.
When should you use Sentence Case?
- Email and Messaging: Fixing accidental ALL CAPS shouting or recovering notes typed on a mobile keyboard without auto-capitalization.
- Modern Web & UI Design: Modern interface guidelines (such as Google Material Design and Apple Human Interface Guidelines) recommend sentence case for button labels, form placeholders, and menus to improve readability.
- Academic and Technical Documentation: Sentence case enhances scanning speed for long paragraphs and descriptions.
