Located within the former Duchy of Swabia, the princely abbey was the second largest ecclesiastical principality of the Swabian Circle by area, after the Prince-Bishopric of Augsburg.
It stretched along the Iller River in the Allgäu region, from Waltenhofen (Martinszell) in the south to Legau and Grönenbach in the northwest, and up to Ronsberg and Unterthingau in the east.

The Imperial city of Kempten itself formed a self-ruling city its own right, enclaved within the abbey's territory.
The Princely Abbey of Kempten covered approximately 1,000 square kilometres (390 square miles) and included some 85 villages and hundreds of hamlets and farms.
At the time of its annexation to Bavaria in 1802, it had some 42,000 subjects.
