Abstract

Numerous studies have evaluated the legibility of various fonts displayed in small print. There has also been a great deal of research into the legibility and recognition of standard highway sign alphabets. There has, however been no attempt to empirically determine large format distance legibility for the growing number of fonts currently available to non-transportation sign manufacturers. The present study systematically evaluated the letter legibility of a set of fonts that are consistent with commercial (e.g., storefront), industrial, transit, and highway signage. The fonts were evaluated in a laboratory setting. Individual test charts were designed for each of the fonts based on the standard Snellen distance visual acuity chart. Recognition acuity thresholds for each of the fonts yielded the minimum visual angle of letter height necessary for their resolution. The relative legibility of each font is discussed, as is the effect of font choice on sign size, and theoretical issues related to critical detail for letter recognition acuity.
