About capitalizing "to" in titles

The word to appears in titles, headlines, and headings across many contexts. Whether you should capitalize it depends entirely on which style guide you are following. The four major standards — AP (Associated Press), APA (American Psychological Association), MLA (Modern Language Association), and Chicago Manual of Style — each have different rules.

In AP Style, the most widely used standard for journalism and web content, articles (a, an, the), short conjunctions (and, but, or, for, nor), and short prepositions under five letters (on, at, to, from, by, in, with, of, up) are lowercase in the middle of a title. The first and last words are always capitalized regardless of what part of speech they are.

APA Style is more aggressive: it lowercases all short words under four letters. Chicago Style lowercases all prepositions regardless of length. MLA Style follows AP rules but also capitalizes all parts of hyphenated words. Sentence case only capitalizes the first word, while ALL CAPS and all lowercase are used for specific design or stylistic purposes.

When writing headlines, blog titles, or academic papers, consistency matters most. Pick one style guide and apply it uniformly. If you are writing for a news website or blog, AP Style is usually the safest choice. For academic papers, follow your instructor or publisher required style.
