These examples show that the approach to always lowercase in, on, by, etc., is inadequate and often leads to wrong results. This title capitalization tool therefore uses more sophisticated methods to capitalize your titles, and takes the context of each word into account. This produces highly accurate results, and all the examples mentioned above are handled correctly.
Title Capitalization RulesThe following section provides an overview of the title case rules. Additional information can be found on the dedicated pages Title Capitalization Rules and Words to Capitalize in a Title.
Title case is not a universal standard. Instead, there are a number of style guides—for example, the Chicago Manual of Style (CMOS) and the MLA Handbook—which each have individual rules for the capitalization of titles. However, there is a consensus about the basic rules:
The main differences between the styles are:
There are further differences between the various capitalization styles, for example regarding hyphenated compounds. Details and a comparison table can be found on the separate Title Case Rules page.
Using the Converter
You can enter text either by typing or by pasting from the clipboard. If the option “Convert When Text Is Pasted” is checked, then pasting text automatically triggers the conversion. Otherwise, press “Enter” to start the conversion (only in single-line mode), or press Ctrl+Enter (on a PC) or Cmd+Enter (on a Mac), or click the “Convert” button. After the conversion, you can copy the results to the clipboard by clicking the “Copy” or “Copy All” button, or by pressing Ctrl+C (this works without marking the text beforehand!).
The converter provides explanations for why each word was capitalized or lowercased. They can be seen by hovering over the words of the converted title, or by switching on the “Show Explanations” option. If a word has a dotted red line under it, the converter is not sufficiently sure of its capitalization. The explanation text will then provide information to help you decide which alternative is the right one. An example title to try this is out with is The Monsters Came by Night.
Options
There are several options available. Only the first two have an influence on the result of the conversion:
Keep Words in All Caps: If this option is checked, then entered words in all caps will not be changed by the converter. For example, the input FREE consultation would be converted to FREE Consultation. If the option is unchecked, the result would be Free Consultation. The converter also recognizes various common acronyms and always converts them to all caps. For example, the inputs usa, uSa, and USA would all result in the output USA, even if “Keep Words in All Caps” is not checked. Unavoidably, acronyms that cannot be distinguished from regular words are exempt from this special handling (e.g., IT/it or US/us).
Use Straight Quotes: If this option is not checked, all quotation marks in the titles will be converted to curly quotes, also known as “smart” quotes or typographer’s quotes. Check this option if you prefer straight quotes, also known as "dumb" quotes or typewriter quotes.
Enable Multi-Line Input: Use this option to switch between single-line and multi-line mode. In single-line mode, only one title can be converted at a time, but in multiple styles, if desired. Multi-line mode, on the other hand, allows converting up to 30 titles at a time, but only in one style.
Show Explanations: If checked, explanations are shown for why each word was capitalized or lowercased.
Highlight Changes: If this option is checked, then all letters whose capitalization has changed are marked in yellow.
Convert When Text Is Pasted: If checked, pasting text triggers the conversion. Clearing the text box before pasting is not necessary since the existing text will be overwritten.
Typography
In addition to converting to title case, the converter also performs small typographic corrections. For example, straight quotes are changed to curly quotes, hyphens are changed to dashes where appropriate, three consecutive dots are converted to an ellipsis, and spaces are removed before question marks, exclamation marks, commas, etc. For example, "I like rock 'n' roll !" becomes “I Like Rock ’n’ Roll!”

Rules for Capitalization in Titles of Articles If you have a look at the title of this article you will see that some letters are capitalized and some are not. Although the capitalization of titles can sometimes depend on the particular style of a writer, institution or publication, there are some general rules to keep in mind. Style Guides The rules for capitalizing titles not only of articles, but also books, papers, speeches, etc, can vary according to a particular style guide, such as Associated Press Stylebook (AP), Chicago Manual of Style, and MLA style. This is known as title case. While you will find similarities between each guide, it's important to pay attention to their differences. Style guide similarities:
The General Rules for Title Case As we can see, there are some exceptions to the general rules for title case set forth by each style guide, but they mostly follow a similar pattern. We know to capitalize the first, last, and important words in a title. Important words include nouns, pronouns, verbs, adverbs, and more. So, generally, these parts of speech are capitalized in titles:
"Capitalize all words in titles of publications and documents, except a, an, the, at, by, for, in, of, on, to, up, and, as, but, or, and nor." What About Sentence Case? Now that we know some of the ins and outs of title case, let's take a look at sentence case. In sentence case, the title is written as if it is a sentence. This is considered a more casual style and is commonly used in newspapers and on the web. Only the first word has a capital letter:
First, one could argue that capitalized words slow down a reader's ability to scan. A title written in sentence case could be perceived as having an uninterrupted flow. Next, some publications prefer this style simply because it's more likely to preserve consistency. With sentence case, there's no nitpicking over the capitalization of a three-letter preposition. You might notice an overall trend toward this style. Many heavy hitters in the publishing industry use sentence case, including The Boston Globe, LA Times, and USA Today. However, if you pick up a copy of The New York Times, you'll see they stick with Title Case. Advanced Rules to Note One of the beautiful complexities of the English language is that, for every rule you learn, there's probably an exception. Here are some advanced rules for title capitalization: Hyphenated Titles Let's take a look at the Chicago Manual of Style's guidelines:
An open compound comes to life when a modifying adjective is used in conjunction with a noun. This creates a new noun. Hopefully warning bells will signal in your mind, as nouns are almost always capitalized.
Let's take a look at both the Chicago and AP Style guidelines:
Prepositions often find themselves on the 'do not capitalize' list. However, when a preposition becomes an important part of a phrasal verb, it does need to be capitalized.
If you are debating how to capitalize titles in research papers and articles, your professor or editor will most likely delegate a certain style. In that case, make sure you visit the handbook on that style guide's website. There will be ample guidance and examples. Aside from that, there are a wealth of other resources and handy tools out there. As you craft your titles, pay careful attention not only to the type of word, but also the length and placement of each word. Furthermore, no matter your personal preference, make sure you write the exact titles of books, newspapers, journals, etc. as they are written on the original document (even if they do not follow common capitalization rules). |
Common Title Capitalization Rules
If you familiarize yourself with common title capitalization rules, it will be easier to write articles, papers, and other pieces.

You should also capitalize adjectives and adverbs in all three styles. You can see this rule in action here:
Do Not Capitalize Short Prepositions

Style Guide Differences and Exceptions
While you will find similarities between each guide, it's important to pay attention to their differences. These are the specific rules and special cases you should consider for each style.
AP Stylebook
In the AP Stylebook, all words with three letters or fewer are lowercase in a title. However, if any of those short words are verbs (e.g., "is," "are," "was," "be"), they are capitalized.
Chicago Style
In Chicago style, all prepositions are lowercase unless they are the first or last word of the title. These include the lengthier ones, such as "between," "among," and "throughout."
MLA Style
In MLA style, words with three letters or fewer are always lowercase. The exception here is if they are the first or last word of the title.

Open Compounds
An open compound comes to life when a modifying adjective is used in conjunction with a noun. This creates a new noun. Hopefully, warning bells will signal in your mind, as nouns are almost always capitalized.
First Word Following a Colon
Both Chicago and AP Stylebook guidelines say you should capitalize the first word after a colon in title case:
In sentence case, you should capitalize the first word after a colon if it begins an independent clause.
In sentence case do not capitalize the first word after a colon if the clause cannot stand alone.
Prepositions That Belong to a Phrasal Verb
Prepositions often find themselves on the "do not capitalize" list. However, when a preposition becomes an important part of a phrasal verb, it does need to be capitalized.
When in Doubt
When you're in doubt and you do not have a reference guide in front of you, here is one general rule recommended by The U.S. Government Printing Office Style Manual:
Furthermore, no matter your personal preference, make sure you write the exact titles of books, newspapers, journals, and other publications as they are written on the original document (even if they do not follow common capitalization rules).
