Which of the following is a common technique used to establish visual hierarchy?

Employing varying sizes and weights of type is a widely recognized technique for establishing visual hierarchy in design. By adjusting the size and weight of text, designers can create a clear path for the viewer's eye, guiding them through the information in order of importance. Larger and bolder type often signifies headings or key messages, drawing attention first, while smaller or lighter text can indicate less critical information. This differentiation helps communicate the structure of the content effectively, allowing viewers to understand what is most important at a glance.

While repetitive patterns, monochromatic color schemes, and the use of multiple images contribute to the overall aesthetic and can influence the viewer's perception, they do not directly address how to prioritize visual elements in the way that varying type sizes and weights do. Hence, using type variation is particularly effective for establishing a clear visual hierarchy.
