What Is Sentence Case?

Sentence case is the most natural-looking way to write headings, paragraphs, and UI copy. It capitalizes the first word of a sentence and keeps everything else in lower case, unless it’s a proper noun.

Definition of sentence case

In sentence case, only the first letter of the first word in a sentence is capitalized (along with proper nouns and acronyms). This mirrors how we normally write in emails, articles, and documentation.

Examples

Here’s what sentence case looks like in practice:

  • This sentence is written in sentence case.
  • Sentence case is easy to read on screens.
  • Pro Case Converter can format sentence case for you automatically.

Why sentence case improves readability

Sentence case is easier to scan than ALL CAPS or inconsistent capitalization. It feels friendlier, especially in product UI, marketing pages, and help articles like this one.
