When working with text, you'll encounter both word limits and character limits—but they measure very different things. Understanding when to use which metric is crucial for writers, students, and marketers alike.
What's the Difference?
Word Count
A "word" is a sequence of characters separated by spaces. The sentence "Hello world" has 2 words.
- Used for: Essays, articles, books, academic papers.
- Example: "Write a 1,500-word essay."
Character Count
A "character" is a single letter, number, punctuation mark, or space. "Hello world" has 11 characters (including the space).
- Used for: Social media, SMS, meta descriptions, database fields.
- Example: "Twitter posts are limited to 280 characters."
Characters Without Spaces
Some platforms count characters but exclude spaces. "Hello world" has 10 characters (no spaces).
- Used for: Some academic requirements, certain programming contexts.
