Title Case — capitalising the first letter of every important word — is the standard for book titles, song titles, movie titles, headlines, chapter headings, and academic paper titles. The rules vary slightly between style guides (AP, Chicago, APA), but the core convention is shared.
Our converter follows AP style by default: capitalise everything except articles (a, an, the), short prepositions (of, in, to, at, by, on, for, up), and coordinating conjunctions (and, but, or, nor) — unless they're the first or last word.
"How to Win Friends and Influence People", "The Catcher in the Rye", "Pride and Prejudice". Title Case is the default convention for published works.
Most academic style guides recommend Title Case for chapter and section headings. Body subheadings vary — APA uses Title Case at top levels and Sentence case for nested headings.
AP-style press releases and traditional newspaper headlines use Title Case. Modern web journalism (BuzzFeed, Vox) increasingly uses Sentence case for a more conversational tone.
Product names, course titles, and event names are conventionally Title Case in marketing copy.
Title Case in bullet points draws the eye to each item's key term, making lists scannable at a glance.
AP capitalises words of 4+ letters and keeps short prepositions/articles lowercase. Chicago is similar but capitalises some additional words by tradition. APA capitalises words of 4+ letters in titles, but uses Sentence case for headings within papers. Our converter follows AP style by default — close enough for most non-academic uses.
Articles (a, an, the), short prepositions (of, in, to, at, on, for), and coordinating conjunctions (and, but, or, nor) are lowercased mid-title because they're functional rather than meaningful — the eye glides over them while content words pop.
Convention varies. AP capitalises both halves of hyphenated compounds in titles ("Self-Care"); Chicago capitalises only the first half ("Self-care"). Our converter capitalises both sides; edit manually if you need Chicago.
Almost. "Capital Case" usually means capitalising every word — even short prepositions. "Title Case" lowercases short connectors. The terms are sometimes used interchangeably; the AP / Chicago / APA versions are the formally-defined ones.
For body copy, web UI labels, and modern-voice headlines. The trend across web design has been toward Sentence case for everything except brand-name logotypes.
