Sheet sizes
Drawing sheet sizes are standardized by the American Society of Mechanical
Engineers (ASME) and the American National Standards Institute (ANSI).
Sheet sizes are designated by letter. These standards are published in
MIL-STD-100A. The drawing sheet sizes you use are determined by the
needs of your command and your need to economically lay out required
information
Figure 1-35 lists drawing sheet sizes and the associated letter designators.
