Readability metrics and reading skills
Several readability checkers using a variety of metrics are available to help you assess the readability of your text. Some are more sophisticated than others. Many checkers offer a grade score to suggest what age or level of education is needed to read the text. Others give you deeper analysis of the language, identifying the interplay of words and sentence structures that make the text difficult for readers to process.
This section covers:
- Flesch–Kincaid reading difficulty grade scores
- Flesch reading ease scores
- School grades.
Caution! Take care when using any readability checking system, because none of them give you the full picture of how readable a piece of text is, or how well it suits your audiences’ reading skills.
If possible, test your text with users to get a better idea of its readability for specific audiences (see Usability testing).
