The Comprehensive Guide to Title Case: Rules, Standards & Examples
What is Title Case (Headline Style)?
Title case—often referred to in publishing as headline style—is the capitalization standard used for titles of books, articles, blog posts, essays, movies, and songs. Rather than capitalizing every letter indiscriminately or only capitalizing the first letter of a sentence, title case distinguishes between major words that carry meaning and minor words that serve grammatical functions.
Major stylebooks—including the Chicago Manual of Style (CMOS), the Associated Press Stylebook (AP), the American Psychological Association (APA), and the Modern Language Association (MLA)—all rely on title case for headlines because it provides a visual hierarchy that makes headings immediately recognizable and easy to scan.
The Core Rules of Title Capitalization
While specific academic manuals differ slightly on edge cases, title capitalization generally follows these universal guidelines:
- Always capitalize the first and last word: No matter what part of speech it is, the first word and the final word of any title are always capitalized. For example, in "What We Are Looking For", the word "For" is capitalized because it ends the title.
- Capitalize all major parts of speech: This includes nouns (Mountain, Student), verbs (Write, Create), pronouns (He, She, What, Who), adjectives (Silent, Quick), and adverbs (Quickly, Never).
- Forms of the verb "to be" are always capitalized: Words like Is, Are, Was, Were, Be, and Been are verbs. Even though "is" has only two letters, it is always capitalized in title case.
- Keep minor function words lowercase: Articles (a, an, the), coordinating conjunctions (and, but, or, for, nor), and short prepositions (at, by, in, of, on, to, up, as, via) remain lowercase in the middle of a title.
- The Subtitle Rule: The first word following a colon (:), em-dash (—), or question mark is always capitalized, as it introduces a new subtitle or independent clause.
- Hyphenated compound words: Major words within hyphenated compounds are capitalized (e.g., "State-of-the-Art" or "Self-Driving Vehicles").
Title Case vs. Sentence Case vs. Capitalized Case
Choosing the correct capitalization style depends heavily on where your text will appear. Here is how they compare across identical phrases:
| Raw Input | Title Case (Editorial) | Capitalized Case | Sentence Case |
|---|---|---|---|
| the catcher in the rye | The Catcher in the Rye | The Catcher In The Rye | The catcher in the rye |
| there is no place like home | There Is No Place Like Home | There Is No Place Like Home | There is no place like home |
| war of the worlds: a modern guide | War of the Worlds: A Modern Guide | War Of The Worlds: A Modern Guide | War of the worlds: A modern guide |
| what are you waiting for | What Are You Waiting For | What Are You Waiting For | What are you waiting for |
