Rules for Title Case

Sentence Case Vs Title Case

Regardless of the style guide you follow, the rules for title case should be the same. You might be following an MLA style guide, AP style (the Associated Press), APA style (the American Psychological Association), the New York Times Style Guide, or even the Chicago Manual of Style. Even when following the 6th edition of any of these, you should follow rules for major and minor words.

You should capitalize major words including nouns, pronouns, proper nouns, verbs, adverbs, and adjectives. You should not capitalize minor words including short prepositions, subordinating conjunctions, coordinating conjunctions, and articles. 

With that said, a few other title case rules include:

  • Always capitalize the first word of the title and the last word of the title. This includes short minor words that might be the first word of a title.
  • Capitalize all words following end punctuation.
  • Capitalize all words longer than three letters.
  • Capitalize both words in a hyphenated compound.

If you follow these rules, use title case.

Rules for Sentence Case

Sentence case vs title case
Sentence case has become second-nature to most people

Sentence case is what you use the majority of the time. This is typically what your grammar checker highlights when you write. A few quick rules about capital letters and lowercase letters in sentence case include:

  • Always capitalize the first word of a sentence.
  • Always capitalize proper nouns.
  • Use lowercase letters the rest of the time.

Sentence case has become second-nature to most people; however, it can be difficult to switch between sentence case and title case. If you don’t know when to apply which set of rules, you might have a hard time following the right set of rules.

When To Use Title Case vs Sentence Case

You should know when to use sentence case and title case. There are several situations where you should use title case. These include:

  • Always use title case in the title of your work. This could include the titles of books, articles, blog posts, and essays.
  • You should use title case in any subtitles you have as well.
  • You need to use title case in your headings and subheadings as well. If you write online, you should use title case for H1 and H2 headings, but you should use sentence case for H3 headings and below.

If you are not writing in one of the situations above, then you should use a sentence case. The instant you move from your headings and titles to the body of your work, you need to move to sentence case. This means following a different set of rules.

Final Word on Sentence Case vs Title Case

It can be difficult to move between sentence case and title case, but as long as you know when to apply which set of rules, you should get your grammar correct. You need to follow title case in your titles, subtitles, and headers, but you need to use sentence case everywhere else.

If you are having a hard time deciding which set of rules to follow, you may want to use an automated grammar checker. If you watch a title case converter go to work, you will learn when you should follow which set of rules. Then, this will be second nature to you.
