For example, in one study, all readability measures, including number of fixations, subjective comprehension, and measured comprehension improved as the fonts got bigger. Most studies found that around 18pt (24px) is the point of diminishing returns where increasing font size stops improving readability. 24px is significantly bigger than the current default font size on Wikipedia (14px on desktop browsers and 16px on mobile browsers). Several studies used Wikipedia articles as their testing data and all of them suggested a font size increase in our core article reading experiences. One study went so far as to name its resulting publication "Make It Big! The Effect of Font Size and Line Spacing ‘Ease of comprehension’ on Online Readability". Another was called "Size Matters (Spacing not): 18 Points for a Dyslexic-friendly Wikipedia."
