Visual Hierarchy of Design is the principle of arranging design elements in a way that guides the viewer’s attention to the most important information first. It uses techniques like size, color, contrast, spacing, alignment, and typography to create a clear order of importance within a layout. In UI/UX and graphic design, visual hierarchy helps users quickly understand content, navigate interfaces easily, and focus on key messages without confusion. By structuring elements effectively, designers can influence how people read, interpret, and interact with a design.
