Which case should I use?
Title Case is used for headlines and book titles. Sentence case is the standard for normal writing and many modern UI labels. camelCase and snake_case are naming conventions in programming, and kebab-case is used for URLs and CSS class names.
Programming case styles
| Style | Example | Commonly used for |
|---|---|---|
| camelCase | userFirstName | JavaScript and Java variables |
| PascalCase | UserFirstName | Classes and React components |
| snake_case | user_first_name | Python, Ruby and database columns |
| kebab-case | user-first-name | URLs, CSS classes and file names |
| UPPERCASE | USER_FIRST_NAME | Constants and environment variables |
Title Case vs Sentence case
Title Case capitalises the main words ("How to Write a Great Headline") and is common in US headlines and book titles. Sentence case capitalises only the first word and proper nouns ("How to write a great headline") and is preferred by many UK publishers, apps and modern websites because it is easier to read.
