This study examines whether the common typographical recommendations for texts in easy-to-read language are helpful. So far, using a sans-serif font in 14 pt has been suggested. The statistical evaluation shows that Thesis TheSans is read significantly faster than Arial. Fonts with serifs are read slightly faster. The font size of 12 pt is large enough. The study clearly indicates that the strict commitment to sans serif fonts—and the Arial font in particular—for texts in easy-to-read language is wrong. The results can be used by designers and clients as a valid decision-making aid when creating barrier-free communication.
