# Title Case Converter

> Apply AP, Chicago, APA or MLA title capitalisation rules — each treats small words differently.

Title case rules differ by style guide. AP and APA lowercase words of three letters or fewer; Chicago lowercases prepositions shorter than five letters; MLA lowercases all prepositions regardless of length. Every guide capitalises the first and last word. This tool applies any of them, or compares all four side by side.

## FAQ

### Why do the style guides disagree?

They draw the line between "important" and "connecting" words differently. AP uses word length as a simple proxy; MLA uses grammatical role; Chicago combines both. For a preposition like "between", AP capitalises it and MLA does not.
