What Is Title Case?
Title case—sometimes called headline style—refers to the convention of capitalizing the most important words in a title while leaving minor words in lowercase. The goal is to draw attention to key concepts without overwhelming the reader with uniform uppercase letters. Understanding which words merit capitalization helps you create clear, visually balanced titles that conform to reader expectations Surprisingly effective..
Major Words
Major words are the core content words that carry meaning. They include:
- Nouns (e.g., Freedom, History)
- Verbs (e.g., Achieve, Explore)
- Adjectives (e.g., Modern, Essential)
- Adverbs (e.g., Quickly, Clearly)
- Pronouns (e.g., Who, They)
- All words that are not functional
These words should always be capitalized in title case.
Minor Words
Minor words are functional elements that link or modify major words. Typical minor words include:
- Articles: a, an, the
- Prepositions (under five letters): in, on, at, by, to, for, from, with
- Coordinating conjunctions: and, but, or, nor, so, yet
- Subordinating conjunctions (short): if, because, as, since
Because they are less essential to the title’s meaning, minor words are generally kept lowercase—unless a style guide dictates otherwise.
Common Style Guides and Their Rules
Different publications and institutions follow distinct conventions. Below are the most widely used style guides and how they treat title capitalization.
APA Style
The American Psychological Association (APA) recommends capitalizing the first word, all nouns, pronouns, verbs, adverbs, and adjectives. Articles, coordinating conjunctions, and prepositions of four letters or fewer remain lowercase. Example: How People Learn: Boosting Motivation
MLA Style
The Modern Language Association (MLA) adopts a similar approach: capitalize the first word, all major words, and any word with four or more letters, even if it’s a preposition or article. Shorter functional words stay lowercase. Example: The Impact of Climate Change on Coastal Communities
Chicago Manual of Style
The Chicago Manual of Style offers flexibility. That said, it suggests capitalizing the first word, all nouns, pronouns, verbs, adjectives, and adverbs. Prepositions and articles are lowercase unless they are the first or last word in the title.
Step‑by‑Step Guide to Capitalizing Titles
Follow these simple steps to apply title case correctly, regardless of which style guide you prefer.
- Write the title in lowercase initially. This prevents preconceived capitalization habits from interfering.
- Identify major words using the list above. Highlight or circle them.
- Capitalize all major words in the title.
- Check minor words: leave articles, short prepositions, and coordinating conjunctions in lowercase, except when they appear as the first or last word.
- Apply style‑specific exceptions: if using MLA, capitalize any preposition or article with four or more letters; if using Chicago, capitalize the last word regardless of its function.
- Proofread: read the title aloud to see if any words feel oddly capitalized. Adjust as needed.
Examples of Correct and Incorrect Capitalization
Below are side‑by‑side comparisons that illustrate proper versus improper title case Nothing fancy..

Title Case vs. Sentence Case
While title case focuses on selective capitalization, sentence case mirrors typical sentence formatting: only the first word and proper nouns are capitalized, with the rest in lowercase. Sentence case is often used for subtitles, table headings, or informal titles The details matter here. But it adds up..
- Title Case: The Complete Guide to Digital Marketing
- Sentence case: The complete guide to digital marketing
Choosing between the two depends on the context and the style guide’s recommendations. Title case generally stands out more in bibliographies and book covers, whereas sentence case can appear in magazine articles or web headers where a softer look is desired.
Most guides skip this. Don't.
