P‐13: Serifs Slow RSVP Reading at Very Small Sizes, but Don't Matter at Larger Sizes

Abstract

Abstract During Rapid Serial Visual Presentation, readers can read sans‐serif type about 20% faster at very small sizes. This advantage disappears at larger sizes. The study was done with fonts specially designed to control typeface parameters other than the serifs. The results suggest that rendering serifs at small sizes may be counterproductive.
