Large homes can have walkways six to 10 feet wide to fit the proportion of the building. A path 30 feet or longer should be five to six feet wide to make it fit the space more comfortably. The minimum width of a walkway is determined by basic needs. Average human shoulder width is 18 inches. Allowing an extra six inches, the walk should be a minimum of 24 inches wide for one person. It must be twice that wide, 48 inches, to accommodate people walking in opposite directions at the same time.
