What is Title Case?
Title Case is the convention that capitalizes the first letter of major words in a title: "The Quick Brown Fox Jumps Over the Lazy Dog". Minor words (articles, short conjunctions, short prepositions) stay lowercase unless they're the first or last word. It's standard in headlines, book titles, magazine articles and most English-language headings on the web.
When to use Title Case
- English content โ blogs, papers, books, news, web headings.
- Song, film and book titles โ global convention, almost mandatory.
- Headings and subheadings for English-market sites.
- Events and campaigns with international branding.
- Formal email subjects in English.
When to avoid Title Case
Many modern publications and tech blogs prefer sentence case for headings: only the first word and proper nouns capitalized. Sentence case feels lighter, more conversational and easier to scan on screens. Title Case can feel overly formal in product UIs and marketing pages. Pick one style per surface and stick with it โ mixing them looks sloppy.
Words that are NOT capitalized
Traditional AP, Chicago and NYT rules agree on keeping these lowercase: articles (a, an, the), short coordinating conjunctions (and, but, or, nor, for, yet, so) and short prepositions of up to three or four letters (in, on, at, of, to, up, by, for). But always capitalize the first and last word of the title, no matter what.
Style variants
- Chicago Manual of Style โ prepositions always lowercase regardless of length.
- AP Stylebook โ capitalize prepositions of four or more letters.
- APA 7 โ capitalize most words of four or more letters.
- House style โ many brands define their own rules; document them.
Common mistakes
The most frequent error is capitalizing every single word (including "the", "of", "in"), an "all caps style" that looks amateur. The second is failing to capitalize the first or last word. The third trap is short verbs like "is", "be", "go": these are verbs, so they ALWAYS take a capital, even at two letters.
How the converter works
We take your text, split it into words and apply blended AP/Chicago rules: first and last word always capitalized, common short minor words lowercase, everything else capitalized. If you need a different style, fine-tune the result manually after copying.
