What the Unique Word Counter Measures
WordCountNow's Unique Word Counter counts the total number of distinct words in your text and calculates your type-token ratio (TTR) — a measure of lexical diversity. A higher TTR means you're using a wider variety of words; a lower TTR suggests repetition.
Type-Token Ratio Explained
TTR = (unique words ÷ total words) × 100. A ratio above 70% suggests rich vocabulary diversity. Below 40% may indicate repetitive language. However, longer texts naturally have lower TTRs — it's harder to use entirely new words as length increases.
When Unique Word Count Matters
