In our age of ubiquitous digital displays, adults often read in short, opportunistic interludes. We consider, for the first time, whether reading outcomes in this unique Interlude Reading can be improved by tailoring typeface to the individual. Hundreds of participants provide a foundation for understanding which fonts people prefer and which make them more effective readers. Results reveal that while 77% believed their preferred font would be fastest to read in; this was only valid for 20%. Differences between best and worst font average 75 words per minute (WPM), with no significant changes in comprehension. High WPM variability for every font suggests that one font does not fit all. We here provide recommendations for favorable fonts related to higher reading speed without sacrificing comprehension and suggest that our methodological approach can be used to model for individuation, allowing digital devices to match their users’ needs in-the-moment.
