What “Title Case” actually means
Title case is not simply capitalizing every word. Style guides agree that the first and last word of a title are always capitalized, and that short articles (a, an, the) and coordinating conjunctions (and, but, or) stay lowercase in the middle of a title. Where they disagree is prepositions: APA and AP capitalize any word of four or more letters — so “With” is capitalized but “to” is not — while Chicago and MLA lowercase every preposition no matter its length.
Getting this right by hand means checking a list of exceptions for every word, which is exactly the kind of small, repetitive rule-following that is easy to get slightly wrong under a deadline. This tool applies the rule set consistently and instantly as you type.
The same title, four ways
Starting from a walk through the park with dogs:
| Style | Result |
|---|---|
| APA | A Walk Through the Park With Dogs |
| Chicago | A Walk through the Park with Dogs |
| AP | A Walk Through the Park With Dogs |
| MLA | A Walk through the Park with Dogs |
Notice “Through” and “With” only capitalize under APA/AP, since Chicago and MLA lowercase prepositions of any length.
Other case modes
- Sentence case capitalizes only the first word of each sentence (and the pronoun “I”) — the style most style guides use for headings and figure captions.
- UPPERCASE / lowercase convert every letter, ignoring word boundaries entirely.
- Capitalize Each Word capitalizes every word with no exceptions — useful for names, not for titles.
- aLtErNaTiNg and tOGGLE case are novelty formats sometimes used for emphasis or "mocking" text online.
