What term describes the width of the flag?

The term that describes the width of the flag is "Hoist." In flag terminology, the hoist refers specifically to the vertical edge of the flag that is attached to the flagpole, while the width of the flag itself is considered the hoist dimension. This dimension is important for understanding how a flag is displayed and its proportions—typically, flags are measured in terms of their hoist (width) and length (height) to establish correct ratios and sizes for display.

In contrast, the term "Fly" refers to the side of the flag that is free and displays away from the flagpole. "Edge" generally refers to the outer boundary or perimeter of the flag and does not specifically denote any measurement related to its width. "Banner" is a more generic term that can refer to any flag or flag-like object that bears a design or emblem, rather than specifically addressing the measurement characteristics of flags. Understanding these terminologies is essential for proper flag protocol and display.
