What is the difference between APA and AP title case?

APA capitalises words of four letters or more, plus major words. AP is similar but treats prepositions of three letters or fewer as lowercase. Both always capitalise the first word.

Which words stay lowercase in a title?

Most styles keep short articles, conjunctions and prepositions lowercase unless they begin or end the title. The exact word lengths differ by style, so pick the one your publisher uses.
