Title case rules used

  • Always capitalized: the first and last word, and the first word after a colon.
  • Chicago style: lowercase articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet) and prepositions of any length (with, between, through…).
  • AP style: lowercase only articles, conjunctions and prepositions of three letters or fewer; capitalize longer ones (With, About).
  • Words with internal capitals (iPhone, NASA) are kept as typed.

Style guides have edge cases (phrasal verbs like “Log In”); review important headlines by hand.

Frequently asked questions

Is “with” capitalized in a title?
