It has an area of 6,049.33 km² and a population of 429,246 at the 2010 Census and 504,418 at the 2020 Census. The regency seat is at the town of Painan, in IV Jurai District.

Pesisir Selatan is located on the coast of West Sumatra and is bordered on the north by the city of Padang, in the east by the regencies of Solok Regency, South Solok Regency and by Kerinci Regency (in the province of Jambi) and in the south by the regency of Muko-Muko (Bengkulu province).

Pesisir Selatan is known for its traditional music, the Rabab Pesisir. The music includes the playing of a rebab (a stringed instrument), accompanied by one or more musicians singing.

As at 2010 South Pesisir Regency consisted of twelve districts (kecamatan), but subsequently three additional districts have been created in the south by the splitting of each of the three existing districts in that sector. All these are tabulated below (listed from south to north, and grouped for convenience into three non-administrative sectors) with their areas and populations at the 2010 Census, and the 2020 Census. The table also includes the locations of the district administrative centres, the number of administrative villages (rural desa and urban kelurahan) in each district, and its postal codes.
