Capitalization rules for titles determine how you format headings, book titles, and article headings across professional and academic writing. Understanding these rules helps you appear polished, credible, and consistent.
Different style guides treat minor words, major words, and punctuation in distinct ways, so it is helpful to compare expectations at a glance.
| Style Guide | Capitalize Major Words | Lowercase Minor Words | Always Capitalize First and Last Word |
|---|---|---|---|
| APA 7th | Yes, unless 3 letters or fewer | Articles, short prepositions, conjunctions | Yes |
| Chicago Manual | Yes, including four or more letters | The, and, or, for, nor | Yes |
| MLA | Yes, including all verbs | The, and, to, but, or, nor | Yes |
| Associated Press | Yes, capitalize first word and all significant words | In, on, at, and, the | Yes |
Title Case vs Sentence Case in Headlines
Title case capitalizes most words in a heading, while sentence case follows standard sentence rules with only the first word and proper nouns capitalized. Choosing between them affects readability, visual hierarchy, and brand tone.
Design systems and content style guides often specify which approach to use for web headings, publication titles, and UI elements to ensure a consistent user experience.
When you apply title case in headlines, you emphasize important terms and create a stronger visual impact, which is especially useful in editorial layouts and search engine result snippets.
Capitalizing Nouns, Verbs, and Adjectives
Most style guides agree that nouns, verbs, adjectives, and adverbs should be capitalized in titles, regardless of length. This principle keeps the core elements of your sentence or headline prominent and easy to scan.
Even short descriptive words such as better, running, or new carry semantic weight and contribute to meaning, so they are typically capitalized rather than left lowercase.
Applying this rule consistently helps readers quickly identify the key topics and actions within a title, supporting both comprehension and search relevance.
Prepositions and Conjunctions in Title Capitalization
Short prepositions and coordinating conjunctions are often lowercased in title case, especially in styles such as APA and Chicago, unless they are the first or last word of the title.
Longer prepositions, including alongside, between, during, and toward, are sometimes capitalized depending on the guide, particularly when they function adjectivally or form part of a key phrase.
Reviewing each style recommendation ensures that minor words in titles are treated consistently and that exceptions for length and position are handled correctly.
First Word, Last Word, and Proper Nouns
Nearly every capitalization policy states that the first and last word of a title should always be capitalized, even if the word is a short conjunction or article. This rule prevents awkward lowercase endings and maintains a professional appearance.
Proper nouns, including names of people, organizations, places, and brands, must be capitalized regardless of their length or role in the title, because they represent specific entities rather than generic terms.
Consistently applying these exceptions reduces ambiguity and keeps headings aligned with standard editorial and publishing expectations.

FAQ
Reader questions
Should I capitalize the word to in a title when it is part of a verb phrase like to run?
Yes, capitalize to when it is part of a verb infinitive, such as to run, to decide, or to improve, because the word functions as part of the main verb in the title.
How do I handle hyphenated words in title capitalization rules?
Treat both parts of a hyphenated compound as major words, capitalizing each element unless the style guide specifies an exception for very short letters.
Do I capitalize the word the when it appears as the first word of a subtitle or heading?
Yes, capitalize the first word of any title or subtitle, including articles like the, a, and an, to follow standard title formatting conventions.
Are numerals in titles treated differently than words for capitalization purposes?
Numerals are typically left as numbers and do not affect word capitalization, but you should maintain consistent formatting for numbered series or titles that include figures.
