About This Tool
What Is the RIX Text Complexity Score?
The RIX Text Complexity score is a readability metric that estimates how difficult a piece of text is to read. It is calculated by comparing the number of long words (typically words with seven or more letters) to the number of sentences in the text. A higher RIX score generally indicates more complex writing, while a lower score suggests the content is easier to understand.
