Case style
How does this calculator work?
AP/Chicago title case capitalises every major word but leaves short articles, conjunctions, and prepositions (a, the, and, of, in, …) in lower case — except as the first word. Other modes include sentence case, UPPER CASE, lower case, camelCase (no spaces, first word lower), and PascalCase (no spaces, every word upper). Paste text, pick style, done.
Formula
How this is calculated
Title case has no single universal rule — it varies by style guide. The two most common editorial standards are AP (Associated Press) and Chicago Manual of Style, which agree on the main principle: capitalise the first and last words of every title, and all "major" words (nouns, verbs, adjectives, adverbs); leave short articles (a, an, the), coordinating conjunctions (and, but, or), and short prepositions (in, of, on, at, by, to, via) in lower case unless they are the first word. This calculator implements that rule for "AP / Chicago" mode.
"Every word capitalised" mode simply upper-cases the first letter of every word regardless of its part of speech — useful for display headings or names. "Sentence case" capitalises only the very first word and leaves all others lower case, matching how normal English sentences are written. UPPER CASE and lower case are straightforward transforms. camelCase removes spaces and capitalises every word except the first — the standard variable-naming convention in JavaScript and Java. PascalCase (also called UpperCamelCase) capitalises every word including the first, used for class and component names.
The small-word list used here covers the most common cases; edge situations (hyphenated compounds, initialisms, proper nouns in lower-case positions) may need manual editing. The tool works entirely in-browser with no data sent to a server.
Frequently asked questions
For journalism and press releases, AP style is the default. For book and article titles in academic or publishing contexts, Chicago style is preferred (the rules are nearly identical). Many websites use "every word capitalised" for SEO headlines because it is simpler to implement consistently. If in doubt, check your organisation's style guide.
They are lower case in the middle of a title but always capitalised if they are the first or (in some style guides) the last word of the title. For example: "The Art of War", "Gone with the Wind", "Beauty and the Beast". This calculator always capitalises the first word regardless of which word it is.
In camelCase the first word is all lowercase and subsequent words are capitalised: "myVariableName". In PascalCase (also called UpperCamelCase) every word is capitalised including the first: "MyVariableName". camelCase is the convention for variables and function names in JavaScript, Java, and Swift. PascalCase is the convention for class names, React components, and C# types.
