Text Case Formats

Different contexts call for different text cases. Programming uses camelCase, PascalCase, and snake_case. Design and writing use Title Case and Sentence case. Databases and URLs commonly use kebab-case or snake_case.

camelCase

First word lowercase, subsequent words capitalized, no spaces. Standard in JavaScript, Java, and Swift for variable names.

PascalCase

Every word starts with uppercase, no spaces. Used for class names and components in most languages.

snake_case

All lowercase, words separated by underscores. Standard in Python, Ruby, and SQL for variables and table names.

kebab-case

All lowercase, words separated by hyphens. Used in CSS class names, URLs, and HTML attributes.

SCREAMING_SNAKE

All uppercase with underscores. Convention for constants in C, Java, and most other languages.

Title Case

Each word capitalized. Used for headings, titles, and proper names.

Frequently Asked Questions

What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable), while PascalCase (also called UpperCamelCase) starts with an uppercase letter (MyVariable). PascalCase is used for class and component names; camelCase for variables and functions.
Which case should I use in Python?
PEP 8 — the Python style guide — recommends snake_case for variables, functions, and module names, and PascalCase (CapWords) for class names. SCREAMING_SNAKE_CASE is used for module-level constants.
Which case is best for URLs?
kebab-case is strongly preferred for URLs. It is readable, SEO-friendly, and avoids case sensitivity issues. Example: /blog/how-to-use-git instead of /blog/HowToUseGit.
Does case conversion affect SEO?
For URLs, use kebab-case — it is the Google-recommended format. For page content, case does not directly affect SEO, but Title Case for headings can improve readability and click-through rates.
