The Readability Guidelines wiki launched in 2019 as a collaborative project, bringing together content professionals from around the world to build evidence-based guidance for anyone making content decisions.

The guidelines have not been updated since 2020, so we've made the decision to retire this wiki on 8th June 2026.

Our sincere thanks to everyone who gave their time and expertise to this project. Your work helped people make better content decisions.

We at CDL still believe content decisions should be grounded in evidence. We hope to bring something new to this space in the future.
