What is title case?
Title case is a capitalization convention for headings in which the first and last words and all "major" words (nouns, pronouns, verbs, adjectives, adverbs) are capitalized, while minor words (short articles, conjunctions and prepositions) are lowercased. Example: "the art of writing well" becomes "The Art of Writing Well".
Which words stay lowercase?
| Type | Words |
|---|---|
| Articles | a, an, the |
| Coordinating conjunctions | and, but, or, nor, for, so, yet |
| Short prepositions | at, by, in, of, off, on, out, to, up, via |
These are still capitalised when they are the first or last word of the title, or the first word after a colon.

Frequently asked questions
What is title case?
Title case is a capitalization style in which the first word, the last word and every major word are capitalized, while short articles, conjunctions and prepositions are left lowercase. It is the standard for book titles, article headlines and academic paper titles.
Which words are not capitalized in title case?
Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet) and short prepositions (in, on, at, to, of, by, up, for) are lowercase — unless they are the first or last word of the title.
What is the difference between AP and Chicago title case?
AP style lowercases prepositions of three letters or fewer; Chicago and MLA lowercase all prepositions regardless of length. APA capitalises words of four letters or more even if they are prepositions.
Is title case the same as capitalizing every word?
No. Capitalizing every word (also called start case) makes small words like "the" and "of" capital too. True title case keeps those words lowercase in the middle of the title.
Should a title be in title case or sentence case?
Journalism and books use title case; many modern blogs, APA reference lists and UK publications prefer sentence case, where only the first word and proper nouns are capitalised. Check your style guide.
