What is the "span"?
In architecture, the span refers to the distance between two supports, such as columns or walls, that an arch, beam, or roof structure covers. This measurement is crucial in determining the strength and design of the structure, as it influences the materials used and the shape of the arch or beam. A larger span often requires stronger materials or additional support to ensure stability, while a smaller span can be achieved with lighter construction. The span plays a key role in the overall functionality and aesthetic of a building, affecting how space is utilized and experienced.
