Title case is a capitalization style where the first letter of each major word in a title is capitalized while minor words like articles, short prepositions, and coordinating conjunctions stay lowercase. The exact rules vary by style guide. AP, Chicago, MLA, APA, NYT, Wikipedia, and Bluebook each define "major" and "minor" words a little differently.
The whole tool sits at the top of this page so you do not have to scroll. Paste or type the title you want to capitalize into the input box. Pick a style guide button above the input, anything from AP and Chicago to Bluebook. The capitalized version appears next to your input as you type, with no delay you can feel.
If you want to capitalize a list of titles, flip the batch toggle and paste one title per line. Each line is converted independently, which is useful for blog editorial calendars, course outlines, episode lists, or chapter headings.
Click Copy to put the converted title on your clipboard, Download to save a .txt file, or Share to send the page link to a teammate. Open the "Show what changed and why" panel under the tool to see, word by word, which words moved between uppercase and lowercase and which rule was applied.
Your text never leaves your browser. Everything happens locally on your device. The page does not log titles, does not send them to a server, and does not need a signup. That is intentional, because most titles you paste here are still confidential drafts.
Style guides exist because different fields care about different things. A newsroom needs titles that scan in a half second. An academic journal needs titles that travel through citation databases. A law review needs titles that line up with court filings. The capitalization rules below are not arbitrary. They follow what the working editors and authors in each field have agreed on, written down, and reprinted across decades of editions.
Image description: a VClar branded illustration that compares title case rules across major style guides for journalism, books, humanities, social science, editorial, encyclopedic, and legal writing.
The AP Stylebook is the default for newspapers, wires, and most digital newsrooms. AP capitalizes the first and last words of a title, plus any word of four letters or longer. Articles, coordinating conjunctions, and prepositions of three letters or fewer stay lowercase. Verbs are always capitalized, even short ones like "Is" or "Are." Example: "Senate Passes Bill After Hours of Debate."
The Chicago Manual of Style is what book editors, university presses, and many literary journals use. Chicago capitalizes principal words and lowercases articles, coordinating conjunctions, prepositions of any length, and "to" when it appears as the marker of an infinitive. Example: "The Lord of the Rings: The Fellowship of the Ring."
The MLA Handbook is closest to Chicago in feel. MLA capitalizes the first and last words and all principal words. Articles, prepositions of any length, and coordinating conjunctions stay lowercase. MLA also stresses that the first word after a colon should be capitalized, which lines up nicely with how subtitle structures actually read. Example: "Reading Borges: A Guide to His Short Fiction."
The APA style from the American Psychological Association is the default for psychology, education, social sciences, nursing, and business research. APA capitalizes any word of four or more letters, plus all verbs regardless of length. Short articles, conjunctions, and prepositions stay lowercase. Example: "The Effect of Sleep on Working Memory in Adolescents."
The New York Times maintains its own house style for headlines and titles. NYT capitalizes principal words, capitalizes verbs (Is, Are, Be), and keeps articles and short conjunctions lowercase. One quirk worth knowing: "of" stays lowercase no matter where it sits, except at the very start or end of a title. Example: "What We Lose When We Forget the Names of Things."
Wikipedia is the big exception to title case. Wikipedia uses sentence case for article titles. Only the first word and proper nouns are capitalized; everything else stays lowercase. This is why Wikipedia article titles read like normal prose: "List of countries and dependencies by population." If you write encyclopedic content, knowledge-base entries, or internal documentation, sentence case usually fits better than title case.
The Bluebook is the citation standard for American legal writing. In Bluebook title case, capitalize all words except articles, conjunctions, and prepositions of four or fewer letters. The rule is fairly liberal compared to Chicago, which means more words end up capitalized. Example: "The Right to Counsel and the Limits of Effective Assistance."
| Style | 4+ Letter Prepositions | Verbs (Is, Are, Be) | Articles (a, an, the) | "To" in Infinitives | Best For |
|---|---|---|---|---|---|
| AP | Capitalize | Capitalize | Lowercase | Lowercase | Journalism, blogs |
| Chicago | Lowercase | Capitalize | Lowercase | Lowercase | Books, scholarly work |
| MLA | Lowercase | Capitalize | Lowercase | Lowercase | Humanities, lit studies |
| APA | Capitalize | Capitalize | Lowercase | Lowercase | Psychology, social science |
| NYT | Capitalize | Capitalize | Lowercase | Lowercase | Editorial, long-form |
| Wikipedia | Lowercase | Lowercase | Lowercase | Lowercase | Encyclopedic, docs |
| Bluebook | Capitalize 5+ only | Capitalize | Lowercase | Lowercase | Legal writing, briefs |

When people ask what to capitalize in a title, they really want a short list. Here is that list, written so you can use it without re-reading a stylebook each time.
Image description: a VClar branded illustration showing capitalization decisions for articles, prepositions, conjunctions, verbs, and pronouns in titles.
Always capitalize
Usually lowercase (style-dependent)
A useful mental shortcut: capitalize anything that carries meaning, lowercase anything that just connects. Possessive words like "my," "your," and "our" always count as meaningful, so they stay capitalized. The grey area is prepositions. Some style guides keep all prepositions lowercase for visual rhythm. AP and APA use a four-letter cutoff because longer words look out of place when lowercased, which is why a word like "From" gets capitalized in AP and APA but lowercased in Chicago and MLA. The converter at the top of this page handles all of this automatically.
After reviewing thousands of headlines, blog drafts, and editorial requests, the same handful of mistakes keep showing up. Each one has a simple fix.
Title case mistakes visual
The fixes below take seconds, but they signal to readers, editors, and reviewers that a publication actually cares about quality. The "Wrong" and "Right" pairs in this section trace the most frequent pattern errors that slip into blog headlines, social posts, course modules, and book chapter titles.
Image description: a VClar branded illustration listing the most frequent title case mistakes that writers, editors, and content marketers should avoid.
1. Capitalizing every word
That style is called "Capitalize Each Word," not title case. Wrong: "The Quick Brown Fox Jumps Over The Lazy Dog." Right: "The Quick Brown Fox Jumps over the Lazy Dog." Articles like "the" stay lowercase mid-title.
2. Forgetting to capitalize the last word
Even a tiny word like "to" gets capitalized when it is the final word. Wrong: "The Things We Run to." Right: "The Things We Run To."
3. Lowercasing "Is" because it is short
"Is" looks small but it is a verb. Verbs are always capitalized in title case. Wrong: "What is a Voice Message." Right: "What Is a Voice Message."
4. Capitalizing "of"
"Of" is a short preposition. It stays lowercase in every modern title case style unless it is the first or last word. Wrong: "The Lord Of The Rings." Right: "The Lord of the Rings."
5. Inconsistent style across a single piece
Pick one style for a publication and stick with it. Mixing AP and Chicago in the same blog feels sloppy to careful readers and confuses any internal style audit.
6. Lowercase "the" at the start
The first word is always capitalized, even articles. Wrong: "the Sun Also Rises." Right: "The Sun Also Rises."
7. Capitalizing only one half of a hyphenated compound
Most styles capitalize both parts of hyphenated open compounds. Wrong: "Self-esteem on a Budget." Right: "Self-Esteem on a Budget."
8. Treating subordinating conjunctions like coordinating ones
Coordinating conjunctions (and, but, or) stay lowercase. Subordinating conjunctions (because, although, when) are capitalized. Wrong: "Run when You Are Tired." Right: "Run When You Are Tired."
9. Missing the colon rule
Capitalize the first word right after a colon in MLA, Chicago, APA, AP, NYT, and Bluebook. Wrong: "Voice Messages: a Practical Guide." Right: "Voice Messages: A Practical Guide."
10. Using sentence case where title case is required
If your publication has a house style and the house style is title case, sentence case will look amateurish even if the content is excellent. The capitalize-my-title workflow takes ten seconds; the credibility you save lasts much longer.
Different professionals reach for different style guides. The summaries below match what real teams use when they ship work to readers.
Image description: a VClar branded illustration covering how bloggers, journalists, authors, academic writers, marketers, and lawyers use title case for their day to day publishing work.
Most marketing blogs use AP. AP is friendlier to digital reading, since words of four or more letters get capitalized and the title scans faster. Keep your H1 between 50 and 60 characters when you can, and put the keyword in the first half.
Newsrooms use AP for digital and wire copy. Larger publications keep an internal style sheet that overrides AP in a handful of places, but the underlying capitalization rules almost always start from AP.
Trade publishers and university presses default to Chicago for both fiction and nonfiction. Chicago is what your copyeditor expects. Chicago is also why every prepositions in long book titles looks lowercase, even the long ones.
Psychology, education, and social science papers use APA. Humanities and literature papers use MLA. Many engineering programs accept either Chicago or APA. Confirm with your journal or department before submission.
Title case helps a video title pop in the YouTube grid. Use AP, push the keyword forward, and keep the title under 70 characters so it survives mobile truncation. Save sentence case for the description.
Bluebook is the citation standard for American legal writing, including case briefs, law review articles, and court filings. Use the Bluebook setting on the converter, then double-check any quoted case names against the original opinion.
Title case in subject lines tends to outperform sentence case for cold and lifecycle email, especially under 50 characters. Mix in personalization, keep it specific, and never go all caps.
LinkedIn favors title case for professional headlines and post titles. X/Twitter is more relaxed, with sentence case common for short, conversational posts. Match the tone of the platform, not the rules of the platform.
Title case is one of several capitalization conventions in regular use. The quick reference below shows the same sentence in each style so you can see them side by side.
Title Case
The Quick Brown Fox Jumps over the Lazy Dog
Sentence case
The quick brown fox jumps over the lazy dog
UPPERCASE
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG
lowercase
the quick brown fox jumps over the lazy dog
Camel case
theQuickBrownFoxJumpsOverTheLazyDog
Pascal case
TheQuickBrownFoxJumpsOverTheLazyDog
Snake case
the_quick_brown_fox_jumps_over_the_lazy_dog
Kebab case
the-quick-brown-fox-jumps-over-the-lazy-dog
Title case is the standard for headlines and book chapters. Sentence case is the standard for body copy, knowledge-base articles, and Wikipedia. Camel, Pascal, snake, and kebab cases are programming conventions. Mixing them inside the same surface, like a mix of camel case and title case in a UI, almost always makes the writing feel uneven.
SEO and CTR visual
Capitalization is not a direct ranking factor, but it changes how a snippet looks in the SERP. Title case usually feels more editorial and tends to lift CTR for blog and content pages compared with sentence case.
Image description: a VClar branded illustration about the relationship between title case, SEO snippets, and click-through rate from search results.
Capitalization is not a direct Google ranking factor. Google reads "fix grammar in voice message" and "Fix Grammar in Voice Message" the same way. So in a strict ranking-formula sense, the answer is no. The story does not stop there, though.
Capitalization does change how titles look in the search results. Title case stands out from snippet text. It signals editorial care. Multiple click-through studies across SEO blogs show small but real lift in CTR when blog titles use title case rather than sentence case. CTR is a behavioral signal that Google watches, and pages that get clicked tend to hold their positions.
Voice search and large language models also lean on well-formed titles. When ChatGPT, Perplexity, or Google's AI Overviews pull a citation, they tend to surface pages whose title and FAQ structure match the question. A clean title in title case reads more like an answer and less like a forum post.
Two practical rules: pick AP or Chicago, and stay consistent across the site. Inconsistent capitalization is a cleanup task that scales painfully. Decide once, document the decision in a one-page style sheet, and use a tool to enforce it on every draft.
Clarity in titles is the same idea as clarity in voice. If your audience cannot scan the headline in a second, they will not read the article. VClar's filler words remover applies the same principle to spoken content. Both surfaces benefit from the same editorial discipline.
Paste the title into the converter at the top of this page and pick a style guide. AP, Chicago, MLA, APA, NYT, Wikipedia, and Bluebook are all supported. The tool capitalizes the major words, lowercases articles and short connectors, and shows a word-by-word explanation under the result so you can see which rule fired for each word.
Capitalise and capitalize are the same word with different spellings. British English uses "capitalise" with an "s", while American English uses "capitalize" with a "z". The title case rules are identical, so this tool works as a capitalise my title converter for UK, Australian, Irish, and New Zealand writers in addition to the American spelling.
Yes. "My" is a possessive pronoun, and possessive pronouns are always capitalized in title case. This applies to AP, Chicago, MLA, APA, NYT, and Bluebook. The same rule covers "your," "our," "his," "her," "its," and "their." Example: "How to Save My Voice Messages from My Phone." Only Wikipedia sentence case leaves "my" lowercase mid-title.
"From" is a four-letter preposition, so the answer depends on the style guide. AP, APA, NYT, and Bluebook capitalize "From" because they capitalize prepositions of four or more letters. Chicago and MLA leave "from" lowercase because they lowercase prepositions of any length. Pick the style that matches your publication and the tool will apply the right rule automatically.
Yes for almost every style. AP and APA explicitly capitalize any word of four or more letters, so all 5-letter words get capitalized. Chicago and MLA capitalize 5-letter nouns, verbs, adjectives, and pronouns, but still lowercase a 5-letter preposition like "with" or "about" because they lowercase prepositions of any length. The only style that consistently lowercases 5-letter words is Wikipedia sentence case.
Title case is a capitalization style where the first letter of each major word in a title is capitalized while minor words like articles, short prepositions, and coordinating conjunctions stay lowercase. The exact list of "minor" words depends on the style guide you follow, such as AP, Chicago, MLA, APA, NYT, Wikipedia, or Bluebook.
AP capitalizes any word that is four letters or longer, including prepositions like "with" and "from." Chicago lowercases prepositions of any length, plus articles and coordinating conjunctions, and lowercases "to" in infinitives. AP is common in news and digital publishing; Chicago is common in books and academic publishing.
Capitalize "the" only if it is the first or last word of the title, or the first word after a colon or dash. In every other position, "the" is an article and stays lowercase in AP, Chicago, MLA, APA, NYT, and Bluebook. In Wikipedia sentence case, only the very first word is capitalized.
"Of" is a short preposition and stays lowercase in nearly every modern title case style, including AP, Chicago, MLA, APA, NYT, and Bluebook. The only time "of" gets capitalized is when it appears as the first or last word of the title, or directly after a colon or dash.
It depends on the style guide. Chicago and MLA lowercase prepositions of any length. AP and APA capitalize prepositions of four or more letters, like "With" and "From." Bluebook lowercases prepositions of four letters or fewer. Pick a style guide and stay consistent across the piece.
Yes. "Is" is a verb, and verbs are always capitalized in title case across every major style guide, even though "is" is only two letters long. The same applies to other short verbs like "are," "be," "was," "were," "do," and "has."
Capitalize the first part of a hyphenated word in every style. For the second part, AP, Chicago, MLA, APA, NYT, and Bluebook capitalize both halves of most hyphenated compounds, so "self-esteem" becomes "Self-Esteem." Wikipedia sentence case lowercases the second half unless it is a proper noun.
Yes in MLA, Chicago, APA, AP, NYT, and Bluebook. The first word after a colon starts a new clause inside the title and is treated like a fresh first word. The same rule applies after an em dash or en dash in most styles.
"To" is lowercase in most modern title case styles, both as a preposition ("Path to Glory") and as the marker in an infinitive ("How to Win"). Capitalize "to" only if it falls at the start or end of the title or right after a colon.
Title case usually performs slightly better in click-through tests than sentence case for short headlines and YouTube titles, especially under 60 characters. Use AP or Chicago, keep keywords in the first half, and avoid all caps except for short emphasis like "NEW" or a known acronym.
Most blogs use title case because it improves CTR, signals editorial polish, and matches how search snippets are displayed. AP is the most common choice for online editorial content, while Chicago is more typical for long-form essays and books. The most important thing is consistency across the site.
Title case capitalizes the major words of a title. Sentence case capitalizes only the first word and any proper nouns, the same way you capitalize a normal sentence. Wikipedia uses sentence case. Most newsrooms, blogs, and publishers use a flavor of title case.
Capitalization is not a direct Google ranking factor. Google can read titles regardless of case. However, title case can lift click-through rate from search results, and CTR is a behavioral signal Google watches. Pick a consistent capitalization style for every page on your site.
In APA 7th edition title case, capitalize the first word, the first word after a colon or dash, all major words, and all words of four or more letters. Lowercase articles ("a," "an," "the"), short conjunctions, and short prepositions. Verbs are always capitalized regardless of length.
Yes. Across AP, Chicago, MLA, APA, NYT, Bluebook, and Wikipedia sentence case, the first word of a title is always capitalized, even if that word would normally be lowercase, like "the," "a," or "to."
For MLA title case, capitalize the first word, the last word, and every major word in between. Lowercase articles ("a," "an," "the"), prepositions of any length, and coordinating conjunctions ("and," "but," "or," "for," "nor"). Capitalize the first word after a colon. Select MLA in the converter at the top of this page and the rule set is applied for you.
Capitalize my title applies title case, where every major word starts with a capital letter. Capitalize my sentence applies sentence case, where only the first word and proper nouns are capitalized. Use the Mode dropdown above the input to switch between Title Case and Sentence case in one click.
Yes. The same tool works as a capitalization corrector, capitalization helper, AP capitalization tool, title capitalization tool, and title capitalizer. Paste a title with mixed or incorrect casing, choose a style guide, and the converter fixes the capitalization in place while explaining each change in the diff panel.
The converter follows the rules published in primary style sources. Every rule set is encoded as data, not hand-tuned heuristics, so we can audit it line by line. The current sources are: AP Stylebook 2024, Chicago Manual of Style 17th edition, MLA Handbook 9th edition, APA Publication Manual 7th edition, the New York Times Manual of Style and Usage, the Wikipedia Manual of Style for article titles, and The Bluebook 21st edition.
The engine recognizes acronyms, roman numerals, hyphenated compounds, possessives, contractions, words with embedded numbers, and a hardcoded list of mixed-case brand names like iPhone, eBay, JavaScript, and macOS. The full brand list and rule set are loaded as JSON by the page so any reader can audit them in the network tab.
Edge cases were tested by hand against more than 200 real titles, including book covers, news headlines, podcast episodes, peer-reviewed paper titles, and YouTube videos. Where two style guides disagreed, we kept the rule that the official publication used in its current edition.
All processing runs in your browser. No title text is sent to a server, logged, cached, or used for analytics. The page works without JavaScript dependencies beyond the on-page engine; no third-party API is called during conversion. Last reviewed: 2026-06-29.
