Readability is the gateway to digital inclusion. The readability level is a metric that estimates how easy or difficult a text is to read. It calculates the minimum level of education a reader needs to easily understand the content. The following examples demonstrate the impact of a poor readability level:
During an online search about an urgent health issue or a legal advice, if you get dense jargon and long sentences, it creates a digital barrier. This barrier prevents access to important information for many people.
Websites that use college-level language exclude millions of visitors. Only 13% of U.S. adults reach this level. Most European nations show similar averages of 12% to 14%.
The readability score provides a way to calculate the level of written text. This score helps to determine how easily readers can understand the text. They analyze sentence length and syllable count. The Flesch-Kincaid Grade Level is one common algorithm.
The Web Content Accessibility Guidelines (WCAG) 3.1.5 sets a clear benchmark for readability. When you follow this standard, you share information with everyone, not just those with advanced literacy.

When you lower the reading level of web content, it removes barriers for many people, including:
The Inclusion Principle: Accessible writing must be clear, not simple. Everyone deserves to use the internet, regardless of language capabilities or educational level.
A core strategy states that you must intentionally design your content to accommodate an inclusive, accessible level, instead of a college reading level. Use the following three pillars to guide your writing:
Cognitive accessibility relies heavily on how a page looks. Dense blocks of text are intimidating and hard to track.
Sometimes, legal or highly technical language is unavoidable. When a page must feature dense text:
Readable websites work better. When you use clear language, fewer users leave, support costs are lower, and user trust is higher.
