Readability and text display - In the beginning, the web user had complete control over how text was displayed. This has been largely replaced by the developer deciding what is "best". However, new research shows that readability and comprehension can be impacted by these choices. See for yourself. Access the ReadabilityMatters.org Sandbox and adjust the sliders to change the text display. Think about what you read and what settings would be better (or worse) for each. Phone, tablet, laptop, desktop? Academic papers, books for pleasure, searching for specific information within text? How about on standardized tests, assignment instructions or even math problem descriptions? Could text display make a difference to you? Post you observations in the Readability demo discussion.

After exploring the Readability Matters Sandbox, helped me understand how text display impacts readability and comprehension. I learned that font size and spacing affect readability a lot.  Changing the text display can make a big difference in how we read and process information.

Customization could be especially helpful for accessibility and learning environments, ensuring that individual preferences are met.
