Enter the total number of unique words or characters and the total number of characters into the Lexical Diversity Calculator. The calculator will evaluate the Lexical Diversity.

## Lexical Diversity Formula

The following two example problems outline the steps and information needed to calculate Lexical Diversity.

LD = UW / TW * 100

Variables:

• LD is the Lexical Diversity (%)
• UW is the total number of unique words or characters
• TW is the total number of characters

To calculate the lexical diversity, divide the number of unique words or characters by the total number of characters, then multiply by 100.

## How to Calculate Lexical Diversity?

The following steps outline how to calculate the Lexical Diversity.

1. First, determine the total number of unique words or characters.
2. Next, determine the total number of characters.
3. Next, gather the formula from above = LD = UW / TW * 100.
4. Finally, calculate the Lexical Diversity.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

total number of unique words or characters = 1000

total number of characters = 10000

LD = UW / TW * 100 = ?
