What to Capitalise in a Title

Capitalizing your titles and headlines is important so that people don’t call you out for using incorrect capitalization. What can be worse than publishing a news article and all of the comments pertain to the capitalization used? Below we’ve outlined the common title capitalization rules so that you can be sure you are using correct capitalization.

There are four main title capitalization styles: Chicago, APA, MLA, and AP. Each publishing house, educational institution, or individual editor should choose which style they want to use.

Title Case Capitalization

Title case is the most common style for headlines. In general, you should use it for H1 tags on pages or as the title of a book. The following rules apply for all four capitalization styles in title case:

  • Capitalize the first word in the title
  • Capitalize the last word in the title
  • Capitalize the important words (see below) in the title

Important words in a title are generally:

  • Adjectives (tiny, large, etc.)
  • Adverbs (quietly, smoothly, etc.)
  • Nouns (tablet, kitchen, book)
  • Pronouns (they, she, he)
  • Subordinating conjunctions (when fewer than 4 letters)
  • Verbs (write, type, create)

These specific guidelines vary amongst the four main capitalization styles, but are great general guidelines. Use our automatic title capitalization tool above for specific use cases.

Words Not Capitalized in Title Case

Some words are generally not capitalized in title case. Again, these vary by style so use our tool above to confirm:

  • Articles (a, an, the)
  • Coordinating Conjunctions (and, but, for)
  • Short (fewer than 4 letters)
  • Prepositions (at, by, from, etc.)

What Is Sentence Case?

Sentence case is another style of title capitalization where only capitalize the first letter of a sentence, proper nouns, and nothing. This style is generally used for subheadings.
