Formatting text correctly makes a big difference in how professional and readable your writing looks. Two popular capitalization styles are Proper Case and Title Case. While they may look similar at first glance, they follow different rules and are used in different contexts. Let's break down the differences.
What Is Proper Case?
Proper Case means every word in a sentence starts with a capital letter. It does not follow headline rules — it simply capitalizes the first letter of all words, no matter how short or unimportant they are.
Example:
Input: proper case vs title case example
Output (Proper Case): Proper Case Vs Title Case Example

What Is Title Case?
Title Case is the style commonly used for book titles, blog posts, essays, and headlines. It capitalizes important words but leaves shorter words (articles, prepositions, and conjunctions) in lowercase, unless they are the first or last word.
Example:
Input: proper case vs title case example
Output (Title Case): Proper Case vs Title Case Example
