The rules for each style
- APA title case
Capitalize every word except articles, conjunctions and prepositions of three letters or fewer. Those stay lowercase unless they come first, last, or right after a colon, dash or end punctuation. Short words that aren't minor words, such as "Is" and "Its", are capitalized. APA uses title case for the titles of papers and headings.
Example: The Role of Sleep in Memory: A Review of Recent Studies
- APA sentence case
Capitalize only the first word, the first word after a colon, dash or end punctuation, and proper nouns. APA uses sentence case for the titles of articles, books and web pages in a reference list.
Example: The role of sleep in memory: A review of recent studies
- MLA title case
Capitalize every word except articles, prepositions and the coordinating conjunctions and, but, for, nor, or, so and yet, whatever their length. The first and last words of the title and of any subtitle are always capitalized.
Example: Learning through Play: Evidence from Early Years Classrooms
- Chicago title case
The same as MLA, except that so and yet are capitalized. In a hyphenated word that starts with a prefix such as anti-, pre- or non-, the part after the prefix stays lowercase.
Example: Anti-inflammatory Drugs and Recovery after Surgery
FAQ
- Is the title case converter free?
- Yes. You don't need an account, and there is no limit on how many titles you convert.
- Do you store the titles I type?
- No. The conversion runs in your browser, so your title never leaves your computer.
- What is the difference between title case and sentence case?
- In title case most words start with a capital letter, and only short or minor words stay lowercase. In sentence case only the first word, the first word of a subtitle and proper nouns are capitalized, as in a normal sentence.
- Why are some short words capitalized in APA?
- APA only lowercases minor words of three letters or fewer: articles, short conjunctions and short prepositions. A short verb, noun or pronoun such as "Is", "Use" or "Its" is a major word, so it is capitalized.
- Does it handle names and places in sentence case?
- Only the ones you list. It can't tell which words are proper nouns, so it lowercases them along with everything else and warns you. Type the names of people, places, organizations and theories under words to keep capitalized, separated by commas, and it keeps them capitalized.
- What does it do with acronyms and words like iPhone?
- It keeps them as you typed them. A word with two or more capitals and no lowercase letters, such as DNA, counts as an acronym, and a word with a capital inside it, such as iPhone, keeps its own capitals. If you type the whole title in capitals, it can't tell the acronyms apart, so it says so.
- How does it treat hyphenated words?
- In APA and MLA title case both parts are capitalized, as in Self-Report, unless the second part is a minor word. Chicago does the same but leaves the part after a prefix such as anti- or pre- lowercase. Sentence case capitalizes only the first part, and only at the start of the title or subtitle.
- Can it tell when a preposition is part of a verb?
- No. Words like up, off and over are lowercased as prepositions. When one is part of a verb, as in "Setting Up a Study", the styles capitalize it, so change it yourself.
