Objective: To assess the legibility of a large set of existing large format display fonts. Background: The enormous selection of fonts allows for creative design; however, while there has been a lot of research on print and computer font legibility, only a limited number of large format display font studies have been conducted. Method: Sixty-four subjects from 19-87 years of age viewed 64 displays using 33 fonts shown on a computer monitor. Viewing began at a very small size, which grew larger to simulate a driver or pedestrian approaching a sign. Subjects attempted to read the displays at the smallest possible size. Threshold legibility was determined for each font. Results and Conclusions: Font selection can make a very big difference in the distance at which a display can be read; however, there are many fonts that have equivalent legibility. Case can sometimes, but not always, have a large impact on display legibility, with uppercase often performing significantly better than lowercase. The choice of serif versus sans-serif alone does not have an important effect on display legibility. Age impaired sign reading ability, but not until the participants were over sixty. Finally, fonts that share a family name (e.g., Times Bold versus Times New Roman) can have dramatically different legibility distances. Application: The results of this research can immediately and directly aid letter manufacturers, display designers, and display owners, as they now know how far away a large number of fonts can be read, and the impact of choosing one font style over another.
