APA Title Case Converter
APA 7 has strict title case rules for headings, article titles, and reference entries. This converter applies them automatically: capitalize words of four letters or more, lowercase short conjunctions and prepositions — except at the start or end.
APA title case rules
Capitalize: first word, last word, and every word of four letters or more. Lowercase: short conjunctions (and, or, but), prepositions (of, in, to) under four letters, and the "to" in infinitives.
Where APA title case applies
Level 1 and 2 headings in APA papers, article titles in reference lists, and titles in citations. Sentence case is used for level 3-5 headings.
Why use a converter
Manually applying "four letters or more" rules across a long title is error-prone. The converter flags and fixes every word per APA 7.
Frequently asked questions
Does APA use title case or sentence case?
Both: title case for level 1-2 headings and reference titles, sentence case for level 3-5 headings. This tool handles the title case side.
Is "to" capitalized in APA?
No — APA lowercases "to" in infinitives (e.g., "How to Write"). The converter applies this rule automatically.
Does this match APA 7?
Yes — the rules follow the APA 7 Publication Manual.
