Automated Readability Index
The Automated Readability Index is a metric used to indicate how difficult a text is to read based on the number of letters per word and words per sentence. Values correspond to the number of years of education a reader requires to understand a text. For example, six corresponds to 11-12-year-old readers, while 12 corresponds to 17-18-year-olds. So, values should be interpreted as follows:
Value | School level | Student age range | Notes |
---|---|---|---|
0-1 | Pre-kindergarten - 1st grade | 3-7 | Basic level for those who just learn to read books. |
1-5 | 1st grade - 5th grade | 7-11 | Very easy to read. |
5-8 | 5th grade - 8th grade | 11-14 | A text is considered ideal for average readers. |
8-11 | 8th grade - 11th grade | 14-17 | Fairly difficult to read. |
11 and above | 11th grade - college | 17 and above | Too hard to read for the majority of readers. |
Since it's based on the American Education system, 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. |
