There are a number of other tensions in the research that are worth naming in an explicit way. The point at which increasing font size stops improving readability performance is very big, almost double the pixel size of our current baseline. Increasing font sizes to that extent could erode trust in Wikipedia by changing its timeless look and feel too radically. It would also make the aesthetics of our interface subjectively less pleasing. More importantly, increasing font sizes to such a degree would make scanning more difficult. The bigger the text, the less information on a page, and scanning reading behaviours benefit from greater information density. People scanning articles would also have to adopt much more extreme scrolling patterns to compensate for the loss of information density. This suggests a tradeoff between readability and scannability, and we will need to find a middle ground.
