Span (design theory)

Span, in design theory, refers to the optimal range over which a system, structure, or process can operate effectively without requiring additional support, extension, or intervention. It involves determining the maximum distance or scope that can be managed efficiently while maintaining performance and stability. By understanding span, designers can create solutions that are both functional and resource-efficient, ensuring materials, components, or processes are used within their effective limits. This concept helps in optimizing design, reducing costs, and enhancing durability and usability across various fields such as architecture, engineering, and user experience.
