What is a Readability Score?

Readability scores indicate how difficult your text is to understand. The most famous and widely-used algorithms are the Flesch Reading Ease and the Flesch-Kincaid Grade Level tests. These formulas mathematically evaluate the average length of your sentences and the average number of syllables per word to determine complexity.

Understanding the Metrics

  • Flesch-Kincaid Grade Level: This translates the score into a U.S. school grade level. For example, a score of 8.0 means that an eighth grader can easily understand the document. For general web content, targeting a grade level of 7 to 8 ensures maximum accessibility.
  • Flesch Reading Ease: This is a score from 0 to 100. A score of 90-100 is very easy to read (suitable for a 5th grader), while a score of 0-30 is very difficult (academic paper level). A score between 60 and 70 is considered standard "Plain English."

Tips to Improve Your Score

If your score is too high (indicating overly complex text), try breaking long, run-on sentences into two smaller ones. Additionally, look for highly complex vocabulary words (4+ syllables) and replace them with simpler, more common synonyms where appropriate.
