An automatic parking system includes a sensor system measuring whether there is a parking section line and positions of surrounding vehicles, and a controller configured to analyze data sensed by thesensor system to calculate parking areas around a subject vehicle, calculate a range allowing generation of a moving path based on the parking areas, provide a moving path range for a parking type that is selected among the moving path ranges provided for the at least two parking types, and an optimal parking area for the selected moving path range, and automatically park the subject vehicle in the optimal parking area.
