# Flesch Reading Ease

Documentation index for AI tools: [/llms.txt](/llms.txt)
 
**Flesch Reading Ease** is a metric that measures the readability of a text based on two factors:

* Sentence length determined by the average number of words in a sentence.
* Word length determined by the average number of syllables in a word.

The score ranges from 0 to 100, with higher scores indicating easier readability. Here's what the scores mean:

| Value | School level | Student age range | Notes |
| --- | --- | --- | --- |
| 100.00 - 90.00 | 5th grade | 11 | Very easy to read. Easily understood by an average 11-year-old student. |
| 90.0 - 80.0 | 6th grade | 11-12 | Easy to read. Conversational English for consumers. |
| 80.0 - 70.0 | 7th grade | 12-13 | Fairly easy to read. |
| 70.0 - 60.0 | 8th grade - 9th grade | 13-15 | Standard, plain English. Easily understood by 13- to 15-year-old students. |
| 60.0 - 50.0 | 10th grade - 12th grade | 15-18 | Fairly difficult to read. |
| 50.0 - 30.0 | College | 18-19 | Difficult to read. |
| 30.0 - 0.0 | College graduate | 22-23 | Very difficult to read. Best understood by university graduates. |

Since it's based on the [American Education system](https://en.wikipedia.org/wiki/Education_in_the_United_States#Educational_stages), school levels and age ranges may be inaccurate for non-English languages. However, it's still possible to compare the relative readability of two topics written in the same language.

| If a metric value is zero, make sure that the project language matches the content language and check the punctuation. |
