Standard Door Sizes. Generally, entry door widths of 30 inches, 32 inches and 36 inches are considered standard and are readily available in home improvement and hardware stores. The standard height of an entry door is 80 inches, and the standard thickness is 1 Â¾ inches. Because they are adjacent to the outside, entry doors are a bit thicker than their interior counterparts to provide additional insulation.
Door Heights. The height of common doors is 6 feet 8 inches. The standard height of the rough opening for a door is the door height plus 2 5/8 inches. The additional room allows for a 3/4-inch top jamb, a shim space above the door jamb and the thickness of underlayment and finish flooring. If you are using pre-hung doors the opening should be 1/2 to 3/4 inch taller than the door and its jamb plus the thickness of any underlayment and finish flooring.
