Editor-quality headline capitalization
Title case is a capitalization convention used for titles, headings, and headlines where the first letter of major words is capitalized while minor words (articles, short prepositions, and coordinating conjunctions) remain lowercase. Unlike simply capitalizing every word, proper title case follows specific editorial rules that vary by style guide.
This Title Case Converter supports nine editorial style guides (including Bluebook and NY Times), word-level capitalization explanations, multi-line batch mode, multi-style comparison, typographic corrections, and intelligently handles brand names, acronyms, and technical terms. All processing runs 100% locally in your browser — your text is never sent to any server.
Headline capitalization refers to the rules governing which words in a title should be capitalized. While it may seem simple, the rules vary significantly between style guides. Getting it wrong can make your content look unprofessional, hurt your credibility with editors, and even affect SEO performance.
The key principle shared by all style guides: always capitalize the first and last word of the title. The differences lie in how they treat prepositions, conjunctions, and articles in the middle of the title.
| Rule | Chicago | AP | APA | MLA | AMA | IEEE | Bluebook | NYT |
|---|---|---|---|---|---|---|---|---|
| Prepositions | < 5 letters lc | ≤ 3 letters lc | ≤ 3 letters lc | All lc | ≤ 3 letters lc | ≤ 3 lc; > 3 cap | ≤ 4 letters lc | ≤ 3 letters lc |
| "with" (4 letters) | Lowercase | Capitalize | Capitalize | Lowercase | Capitalize | Capitalize | Lowercase | Capitalize |
| "yet" / "so" | Capitalize | Lowercase | Lowercase | Lowercase | Lowercase | Lowercase | Lowercase | Lowercase |
| "to" (infinitive) | Lowercase | Capitalize | Lowercase | Lowercase | Lowercase | Lowercase | Lowercase | Lowercase |
| 2-letter verbs (is, be) | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize |
| Subordinating conj. | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize | Capitalize |
| First & last word | Always cap | Always cap | Always cap | Always cap | Always cap | Always cap | Always cap | Always cap |
| Hyphenated words | Cap major elements | Cap all elements | Cap major elements | Cap major elements | Cap major elements | Cap major elements | Cap major elements | Cap major elements |
Start case (every word capitalized) is not the same as proper title case. Articles, short prepositions, and conjunctions should be lowercase.
Short verbs like 'Is', 'Be', 'Do', and 'Go' should always be capitalized. They are verbs, not prepositions or articles.
Mixing rules from different style guides creates inconsistency. Choose one style guide and apply it consistently.
Brand names like iPhone, macOS, ChatGPT, and YouTube have specific casing that should be preserved in titles.
Google typically displays 50-60 characters in search results. Longer titles get truncated with an ellipsis, potentially hiding important keywords.
Words like 'Ultimate', 'Proven', 'Essential', and 'Complete' increase click-through rates. Use them strategically without overloading.
Place your most important keywords near the beginning of the title where they are most visible in search results and social shares.
Choose one title case style and apply it consistently across your site. Inconsistent capitalization looks unprofessional to readers and search engines.
ALL CAPS titles can appear aggressive and are harder to read. They may also be interpreted as spam by search engines and social platforms.
Mobile SERP displays are narrower and truncate at fewer characters. Use the mobile SERP fit indicator to ensure your title looks good on all devices.
Headlines are the first thing readers see. Research shows that 80% of people read headlines, but only 20% read the full article. A properly capitalized headline signals professionalism, credibility, and attention to detail.
In academic and scientific publishing, incorrect title capitalization can lead to manuscript rejection. In marketing and SEO, well-crafted titles directly impact click-through rates and engagement. In journalism, consistent headline formatting is a core editorial standard.
Many brand names have unconventional capitalization that should be preserved in titles. This tool includes a built-in dictionary of over 200 brand names that are automatically handled correctly.
