What do you capitalise in a title?

Which words you capitalise depends on the capitalisation style you use. Title case and sentence case are two common capitalisation styles that follow different rules:

  • In title case, the initial letter of every major word (such as a verb) is capitalised, while minor words (such as coordinating conjunctions) are typically in lowercase. Title case is most frequently used for headings and the titles of published works.
  • In sentence case, only the first word of a sentence is capitalised, along with any proper nouns (names of specific people, places, etc.).

However, these rules may vary. Follow the advice outlined in your style guide.
