Dollar coins have never been very popular in the United States since the removal of specie coins from circulation. Despite efforts by the government to promote their use, such as the Presidential $1 Coin Program, most Americans currently use the one-dollar bill rather than dollar coins.
Width and Height. An interior passage door is any door that you use to move from one room to another, and the code requires these to be 80 inches in height. Because this corresponds to 6 feet 8 inches, door manufacturers refer to this as a 6/8 door.
Garage Door Heights. One very important factor that must not be overlooked is the height of the garage doors. Again, depending on the sizes of your cars, garage door heights vary. A typical 2 car garage door would be about seven feet in height. You may also have your garage doors measured up to eight feet high, nine feet, twelve, fourteen, sixteen and up to eighteen feet high.
