Answer 3

For most guide signs, the legends are so variable that a standardized size is not appropriate.

The sign size is determined primarily by the length of the message, and the size of lettering and spacing necessary for proper legibility.

However, for signs with standardized designs, such as by-pass and route signs, it is practical to use the standard sizes that are given in the "Standard Highway Signs" book.
