how wide is the average entrance door
Standard Exterior Doors. Most building districts adhere to the International Residential Code, which requires the main entry door of a house to be at least 36 inches wide and 80 inches high. The IRC doesn't place restrictions on any other exterior door, however, and lumberyards stock other sizes. The most common widths are 28, 30 and 32 inches. Exterior doors seldom are shorter than 80 inches, but you can find doors 7 and 8 feet in height.
