What Is Sentence Case?
Sentence case is a text formatting style where the first letter of a sentence is capitalized while the remaining letters are generally written in lowercase.
For example:
Original: THIS IS AN EXAMPLE OF TEXT. HERE IS ANOTHER SENTENCE.
Sentence Case: This is an example of text. Here is another sentence.
It is commonly used for paragraphs, descriptions, messages, documents, and other types of readable content. Sentence case is also called sentence-style capitalization. It is the style most people use in emails, captions and body text.
- Same text, different styles:
- Original: the art of war and peace
- Sentence case: The art of war and peace
- Title Case: The Art of War and Peace
- Lowercase: the art of war and peace
Because the rest of the text is converted to lowercase, names, places and acronyms (for example London or NASA) need to be capitalized again by hand.

Can I use sentence case for paragraphs?
