Is "His" Capitalized in a Title?

Yes. "His" is a possessive pronoun, and every major style guide capitalizes pronouns in a title, however short they are. Only articles, prepositions, and some conjunctions stay lowercase, and "his" is none of those.

Why Three Letters Is Not a Reason to Lowercase

AP, APA, and AMA lowercase certain words of three letters or fewer, which makes "his" look like a candidate. But their rule covers only prepositions and conjunctions (plus the articles a, an, and the). "His" stands in for a noun, so it counts as a major word in every guide.

The same goes for "her", "he", "its", and "their". In a title, they are all capitalized.

"His" in Religious Titles and Quotations

Some religious texts capitalize "His" mid-sentence when it refers to God. That is a separate convention about reverence, not title case. In a title, "His" is capitalized either way, so the question only comes up in body text.

Real Titles With "His"

• His Dark Materials (Philip Pullman): first word
• Every Man in His Humour (Ben Jonson): capitalized mid-title

"His" in Sentence Case

APA reference lists, many news sites, and most UI text use sentence case instead of title case. There, only the first word and proper nouns get capitals, so "his" is lowercase unless it starts the title: "A man and his dog." Pick one of the two styles for a whole set of headings rather than mixing them.
