How to Convert Text to Title Case: Rules, Examples, and Step-by-Step Guide
Capitalizing titles sounds simple until you encounter short words like with, in, and, or is. Whether you are writing a blog post headline, an academic essay title, a book chapter, or an email subject line, knowing which words to capitalize and which to keep lowercase can be confusing. This guide gives you the exact rules, practical examples, style guide differences, and a quick method to convert text instantly.
The Core Rule: Quick Answer
In standard title case, you follow three primary rules:
- Always capitalize the first word and the last word of the title, regardless of what part of speech they are.
- Capitalize all major words: nouns, verbs (including short ones like is, are, and was), adjectives, adverbs, and pronouns.
- Keep minor words in lowercase unless they are the first or last word:
- Articles: a, an, the
- Coordinating conjunctions: and, but, for, or, nor
- Short prepositions (under four letters in most styles): in, on, at, by, to, of, for, up

Method 2: Manual Conversion Steps
If you are formatting a headline by hand, follow this sequence:
- Start and finish with capitals: Capitalize the very first character of the title and the first letter of the final word.
- Capitalize all nouns and verbs: Ensure words like Dog, Running, Sees, Is, Are, Was, Has are capitalized. Remember that Is is a verb and must always be capitalized.
- Check prepositions and articles in the middle: Lowercase in, on, at, to, of, a, an, the, and, but when they appear in the middle of the phrase.
- Handle subtitles after punctuation: If your title contains a colon (:), dash (—), or question mark (?), always capitalize the first word that immediately follows the punctuation mark.

Style Guide Differences: Chicago vs. APA vs. AP vs. MLA
Different publishing standards handle title capitalization with slight variations. Here is how the most common style guides compare:
| Style Guide | Primary Use | Preposition Rule | Example Treatment |
|---|---|---|---|
| Chicago Manual of Style (CMOS) | Books, publishing, history, literature | Lowercase prepositions regardless of length (e.g., between, through, with) | A River Runs through It |
| APA Style (7th Edition) | Academic papers, psychology, social sciences | Capitalize prepositions of 4 or more letters (e.g., With, From, Between) | A River Runs Through It |
| Associated Press (AP) | Journalism, news, press releases | Capitalize all words of 4 or more letters, regardless of part of speech | Walking With the Team |
| MLA Handbook (9th Edition) | Humanities, literature, academic essays | Lowercase all prepositions, conjunctions, and articles | Waiting for the Train |
Common Title Case Mistakes to Avoid
- Lowercasing the verb "is" or "was": Because "is" is only two letters long, writers often mistake it for a minor word. However, "is" is a verb and must always be capitalized (e.g., What Time Is It? not What Time is It?).
- Capitalizing prepositions in the middle: Writing The Benefits Of Exercise instead of The Benefits of Exercise.
- Forgetting to capitalize the last word: Writing What Are You Looking for? instead of What Are You Looking For?. The final word is always capitalized in title case.

Frequently Asked Questions
Is the word "with" capitalized in title case?
It depends on the style guide. In Chicago and MLA styles, "with" is a preposition and is kept lowercase in the middle of a title. In APA and AP styles, prepositions of four or more letters are capitalized, so "With" is capitalized.
Why is "is" always capitalized in titles?
"Is" is a form of the verb "to be". In title case rules across all major style guides, all verbs are considered major words and must be capitalized, regardless of how few letters they have.
What is the difference between Title Case and Capitalized Case?
Capitalized Case (also called Start Case) capitalizes the first letter of literally every word without exception (e.g., The Old Man And The Sea). Title Case is grammatically nuanced: it leaves minor connecting words like and, the, and of in lowercase (e.g., The Old Man and the Sea).
Should the first word after a colon be capitalized in a title?
Yes. In title case, the text following a colon or em-dash is treated as the subtitle. Subtitles follow the same rules as the main title, meaning the first word after the colon is always capitalized.
