Using lower-case fonts varying only in serif size (0%, 5%, and 10% cap height), we assessed legibility using size thresholds and reading speed. Five percentage serif fonts were slightly more legible than sans serif, but the average inter-letter spacing increase that serifs themselves impose, predicts greater enhancement than we observed. RSVP and continuous reading speeds showed no effect of serifs. When text is small or distant, serifs may, then, produce a tiny legibility increase due to the concomitant increase in spacing. However, our data exhibited no difference in legibility between typefaces that differ only in the presence or absence of serifs.
我们使用仅在衬线大小（大写字母高度的0%、5%和10%）上有所变化的小写字体，通过字号阈值和阅读速度来评估易读性。5%字号的衬线字体比无衬线字体略易读，但衬线本身导致的字母间平均间距增加，预计会带来比我们观察到的更大的易读性提升。快速序列视觉呈现（RSVP）和连续阅读速度均未显示出衬线的影响。因此，当文本较小或较远时，由于随之而来的间距增加，衬线可能会使易读性略有提高。然而，我们的数据显示，仅在有无衬线方面存在差异的字体，在易读性上并无不同。
