What is the significance of the margin on blueprints?

The significance of the margin on blueprints primarily lies in providing a buffer between the drawing and the edge of the paper. This buffer is crucial because it protects important details of the drawing from being trimmed off or damaged when the document is cut or when it undergoes handling. By maintaining a space around the drawing, the margin ensures that the essential features of the blueprint are preserved, which is vital for clarity and usability.

In addition to protecting the drawing, the margin can also facilitate the handling process during printing and binding, minimizing the risk of accidental cuts to the design itself. The functionality of the margin is essential in the context of professional standards for blueprint presentation, making it an integral part of their design.
