Title case rules

Capitalise the first and last word and every major word. Keep articles (a, an, the), short conjunctions (and, but, or, nor) and short prepositions (of, in, on, at, to, by, for) in lower case. AP style capitalises prepositions of four or more letters; Chicago keeps all prepositions lower case. The converter follows the rules both share.

Case Converter: questions

What is title case?+

Capitalising the main words of a title. Nouns, verbs, adjectives and adverbs start with a capital, while short articles, conjunctions and prepositions stay lower case unless they come first or last: The Lord of the Rings.

What is sentence case?+

Writing like a normal sentence: only the first word and proper nouns get a capital. Many style guides, including Apple's and Google's, use sentence case for headings and buttons.

What's the difference between camelCase, snake_case and kebab-case?+

They're ways to write several words without spaces in code. camelCase joins words with a capital for each new word (userName), PascalCase capitalises the first one too (UserName), snake_case uses underscores (user_name) and kebab-case uses hyphens (user-name). CONSTANT_CASE is snake_case in capitals.

How do I change case on a Mac?+

In Pages, TextEdit and many Mac apps, select the text and Control-click it, then choose Transformations › Make Upper Case, Make Lower Case or Capitalize. In Word, press Shift-F3 to cycle between cases.
