What to Capitalize in a Title
Correct capitalization is crucial for titles and headlines. If you're unsure what to capitalize, use our title capitalization tool above. For specific rules, see the guidelines below.
There are four main title capitalization styles: CMS, APA, MLA, and AP. Each has its own rules for which words to capitalize, and can be written in either title case or sentence case capitalization.
What Is Title Case Capitalization?
Title case is the most common form of title and headline capitalization, used in all major styles for book titles, movie titles, song names, plays, and other works.
General rules for title case across all styles:
- Capitalize the first word in the title
- Capitalize the last word in the title
- Capitalize important words in the title
Important words generally include:
- Adjectives (tiny, large, etc.)
- Adverbs (quietly, smoothly, etc.)
- Nouns (tablet, kitchen, book)
- Pronouns (they, she, he)
- Subordinating conjunctions (when fewer than 5 letters)
- Verbs (write, type, create)
Title case is widely used for book titles, headlines, article titles, etc. When multiple letters need to be capitalized in a title, title case capitalization is applied.
Words Not Capitalized in Title Case
While most words are capitalized in title case, certain short words and conjunctions are not, depending on the specific style. These include:
- Articles (a, an, the)
- Coordinating Conjunctions (and, but, for)
- Short words (fewer than 4 letters)
- Prepositions (at, by, to, etc.)
