Today we are going to figure out what it is and how can we use it to measure our AI-generated content.

What Is Flesh Reading Ease?

Flesch reading ease is a readability test that measures how easy it is for a reader to understand a piece of text. It is calculated using two factors: the average sentence length and the average number of syllables per word.

The Flesch reading ease score is a number between 0 and 100, with 100 being the easiest to read. A score of 60 or above is considered to be easy to read, while a score of 30 or below is considered to be difficult to read.

The Flesch reading ease score can be calculated using the following formula:

Flesch Reading Ease = 206.835 - (1.015 x ASL) - (84.6 x ASW)


  • ASL = average sentence length (number of words/number of sentences)

  • ASW = average number of syllables per word

The Flesch reading ease score is a useful tool for measuring the readability of your text. It can help you to make sure that your text is easy to read for your target audience.

What Is the Best Score?

Simply say, the higher the score value is, the better.

The perfect score on the Flesch reading ease test is 100, which means that the text is very easy to read. However, it is not always possible to achieve a perfect score, especially if the text is technical or complex.

Why We Should Care About the Score?

There are several reasons why we should care about Flesch reading ease.

First, it can help us to ensure that our writing is accessible to a wide audience. If our writing is too difficult to read, people will be less likely to understand it. This can be a problem for both writers and readers. For writers, it means that their work may not be as effective as it could be. For readers, it means that they may have to spend more time and effort trying to understand the text, which can be frustrating and even lead to them giving up.

Second, it can help us to improve our writing style. By making our writing easier to read, we can make it more engaging and persuasive. This is because people are more likely to pay attention to text that is easy to read. Additionally, easier-to-read text is often more likely to be remembered.

Finally, it can have a positive impact on our SEO. Google and other search engines take into account the readability of text when ranking websites in search results. This means that easier-to-read text can help our websites to rank higher in search results.

Overall, by making our writing easier to read, we can improve the accessibility, effectiveness, and SEO of our work.

  • Use short sentences.

By following these tips, you can make your text easier to read and understand.
