Q. What are the dimensions of the direction board?

Answer

The dimensions of the direction board can be 3 mm, 5 mm, 5.7 mm, and 7-9 mm. There is a long history of commercial signage. It appears that storefront and advertising signage developed separately in the east and west. Ancient civilizations such as the Egyptians, Romans, and Greeks all made use of signs. The Romans used billboards both to advertise goods and services and to publicize major events.
