Sofie Beier In legibility research and type design practice, readers are often treated as belonging to one of two age groups: the young and the old. Young adults are used as the default benchmark for “normal” reading, while older readers are studied once age-related decline becomes visible. In between lies a large, influential group that is rarely addressed: middle-aged readers.
This talk presents new results from reading experiments conducted at the Centre for Visibility Design, in which middle-aged readers were included as a distinct group. The findings show that middle age is not a neutral midpoint. Subtle but systematic visual and cognitive changes begin earlier than we typically assume, and these changes affect how typography is processed.
By focusing on differences in reading performance across age groups, this presentation highlights how middle-aged readers respond differently to typographic parameters such as font size and optical size, and why this matters for everyday type design decisions.
A typeface that looks robust when tested on young readers may already be under strain for much of the adult population. Making middle-aged readers visible in research and design practice can lead to more resilient typography, ensuring that typefaces work across the full span of adult reading life.
