Guidelines for the Design and Use of Scale Ladders

To understand why the nanoscale is different, we need to appreciate just how small it is. One common way to represent the nanoscale visually relies on scale ladders, diagrams that show how objects are related by size. Using existing research on understanding size and scale, the Visualization Laboratory carried out a series of experiments to develop a scale ladder and guidelines for their design and use. These guidelines are based on several rounds of formative evaluation, and provide insight into what aspects of a scale ladder are most critical in communicating with visitors, and how they...
