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.
Standard height is 79.5 inches. When measuring for entry and interior doors, youâll need three measurements. Accuracy is very important. Measure the width and height of your old door and round this number up to full inches. As an example, you would round up a measurement of 79.5 inches to 80 inches. Next, measure the jamb width. Measure from the back of the interior trim to the back of the exterior trim. An accurate measurement here means your new pre-hung door will fit flush to the wall without jamb extensions.
