AP, Chicago and APA: what is different
- AP (news): capitalise every word except articles, and conjunctions and prepositions of three letters or fewer, which stay lower case. Walking Through the Park.
- Chicago (books): keep all prepositions lower case, however long. Walking through the Park.
- APA (academic): capitalise every word of four letters or more, including prepositions such as With and From.
All three capitalise the first and last word and keep acronyms such as NASA in capitals. For other cases, such as upper case or snake_case, use the Case Converter, and check that your headline fits with the Character Counter.

Frequently asked questions
What is title case?
A style where the main words of a title start with a capital letter, while short words like a, the and of stay lowercase.
What is the difference between AP and Chicago?
AP keeps fewer words lowercase, while Chicago lowercases more short prepositions such as as, if, off and via. Both always capitalise the first and last word.
How does APA style work?
APA capitalises all words of four letters or more, plus important shorter words, and keeps short articles, conjunctions and prepositions lowercase.
What about words after a colon?
The first word after a colon is capitalised, as most style guides require.
Can I convert to sentence case instead?
Use our Case Converter for sentence case, UPPER CASE and other styles.
Are hyphenated words capitalised?
Yes. Each part of a hyphenated word is capitalised, such as Well-Known or Step-by-Step.
Should I use title case or sentence case for headlines?
Many news sites and blogs use sentence case, while books, academic papers and many brands use title case. Pick one and use it consistently.
Is the first word after a colon capitalised?
Yes in all three styles: a subtitle after a colon starts with a capital, as in Coffee: A Guide for Beginners.
Are short verbs like is and be capitalised?
Yes. Verbs are always capitalised in AP, Chicago and APA, even when they are short.
Which style should I use for a blog post?
Pick one and stay consistent. Many blogs follow AP because it is simple, while publishers and book titles usually follow Chicago. Academic papers and references use APA.
