Yes. Capitalize "Your" in title case because it is a pronoun. Write How to Format Your Book, not How to Format your Book. The answer changes only when you are using sentence case, where a word in the middle of the title is normally lowercase.
The major English title-case systems agree on this specific word, even though they disagree about some prepositions, conjunctions, and hyphenated compounds. The practical rule is simple: decide whether the title uses title case or sentence case, then apply one style consistently.
Understanding title case rules
Title case capitalizes the opening word and principal words, including nouns, pronouns, verbs, adjectives, and adverbs. Rules for minor words and the final word depend on the style guide. The examples below use Chicago title case unless another style is named.
The Chicago Manual of Style confirms that pronouns are capitalized in headline-style titles. APA's title-case guidance also treats major words, including pronouns, as capitalized. MLA uses headline-style capitalization for English-language titles and explains that its rules are conventions for consistency, not a measure of how important each word is.
| Style | Example | What happens to "your" |
|---|---|---|
| Title case | Build Your First Author Website | Capitalized |
| Sentence case | Build your first author website | Lowercase in the middle |
| All caps | BUILD YOUR FIRST AUTHOR WEBSITE | All words are capitals by design |
Capitalization of specific words
The part of speech matters more than word length. "Your" is the possessive form of the personal pronoun "you," so it belongs with the principal words. The MLA Style Center identifies "your" as a possessive form of a personal pronoun.
Other words require a style-specific check:
- Articles: "a," "an," and "the" are generally lowercase in the middle of a title.
- Coordinating conjunctions: words such as "and," "but," and "or" are generally lowercase.
- Prepositions: Chicago changed its rule in the 18th edition (2024): prepositions of five letters or more are capitalized, while shorter ones are usually lowercase in the middle of a title. The older rule lowercased prepositions regardless of length. APA uses a four-letter threshold; use the edition and style your publication requires.
- Verbs: capitalize verbs, including short forms such as "Is" and "Be."
- First and last words: Chicago capitalizes both even when they would otherwise be lowercase. Do not assume that final-word rule applies to every title-case system.
The official Chicago 18th-edition changes list, section 8.160, documents the five-letter preposition rule. For example, write Your Guide About Writing in current Chicago style, while Your Guide to Writing keeps the shorter preposition lowercase. Source checked September 5, 2026.
Those differences explain why a converter may produce two valid-looking answers for the same title. They do not create uncertainty about "Your."
The role of "Your" in title case
"Your" shows that something belongs to or is associated with the person being addressed. Its grammatical job, not its emphasis, is why title case gives it a capital letter.
These are correctly capitalized:
- How to Find Your Writing Voice
- Protect Your Work Before Publication
- What Is Your Book About?
- Your Guide to Ebook Formatting
The same wording in sentence case would be How to find your writing voice and Protect your work before publication. Sentence case generally capitalizes the opening word, proper names, and any words or abbreviations that are normally capitalized.
Examples of title capitalization
| Unedited text | Chicago-style title case | Sentence case |
|---|---|---|
| how to publish your first ebook | How to Publish Your First Ebook | How to publish your first ebook |
| is your manuscript ready for print? | Is Your Manuscript Ready for Print? | Is your manuscript ready for print? |
| a guide to your author platform | A Guide to Your Author Platform | A guide to your author platform |
| what your editor needs to know | What Your Editor Needs to Know | What your editor needs to know |
Notice that "to" and "for" stay lowercase in the Chicago column, while "Your" remains capitalized. The opening "A" is capitalized because it begins the title.
Common questions about title capitalization
What if a brand styles the title differently? Preserve an official brand or work title when accuracy requires it. A publication's house style may also override a general guide.
What comes after a colon? Most title-case systems capitalize the first word after a colon, even if it is an article or preposition.
What about a hyphenated compound? Rules for the second element vary. Check the selected guide instead of assuming every part receives a capital.
Can a title mix title case and sentence case? It can, but the result usually looks accidental. Use one system across headings of the same level.
Practical tips for writing titles
- Choose the governing style: Chicago, APA, MLA, AP, or a publication's house rules.
- Write the title in ordinary words before changing capitalization.
- Mark the first word, last word, and every noun, pronoun, verb, adjective, and adverb.
- Apply that guide's rules for articles, conjunctions, prepositions, and hyphenated compounds.
- Check proper names against the spelling used by the person, company, product, or publication.
- Compare the result with nearby titles so a page does not switch styles without a reason.
A title-case converter can catch routine mistakes, but it cannot always identify a word's grammatical function or know which house style governs the document. Treat it as a check, not the authority.
Title-case decision sheet
Record the governing style and test “your” in the actual title rather than applying a remembered shortcut.
