What is the recommended space between separate notes in technical drawings?

In technical drawings, the recommended spacing between separate notes is twice the height of the letters. This standard ensures clarity and legibility, making it easier for someone reading the drawing to distinguish between different notes. Having adequate spacing helps to avoid confusion and reduces the likelihood of misinterpretation of the information provided. When notes are spaced this way, it provides a balanced appearance on the drawing, improving overall readability and allowing for efficient communication of technical details.

Choosing a spacing that is proportional to the letter height helps maintain consistency, which is critical in professional documentation. It strikes a balance between being close enough to associate related notes and far enough apart to avoid overlap and merging of information.
