What is the largest type of American flag?

The largest type of American flag is known as the Garrison flag. This flag measures 20 feet by 38 feet and is typically used for days of prominence or special occasions, such as national holidays or during ceremonies. The Garrison flag is intended to be a source of pride and can be seen flying over military installations to honor and represent the United States.

In contrast, the Post flag, which is smaller, typically measures 10 feet by 19 feet and is used at military posts. The Storm flag, even smaller than the Post flag, is designed for use in adverse weather conditions and measures 5 feet by 9.5 feet. Signal flags are also not appropriate here, as they are used for communication at sea and do not represent the same standards or dimensions as the Garrison flag.

The distinction in size and use between these various flags emphasizes the Garrison flag's purpose as a symbol of national pride and its significant visibility during events, marking it as the largest of the American flags.
