The city encompasses 109.96 square miles of land and 1.36 square miles of water, reflecting the rolling terrain and modest waterways that characterize this part of the Midwest.

Public transit options in the area are limited, as is typical for rural Ohio communities, making personal vehicle ownership the primary mode of transportation for most residents.
History
Fredericktown was established in the early nineteenth century as settlers moved into central Ohio following the opening of the Northwest Territory, and it developed as a trading and agricultural center for the surrounding Knox County region. The town's growth was shaped by the fertile farmland of the area and by its connections to nearby communities, helping it become a stable residential and commercial hub over the generations. Like many Ohio small towns, Fredericktown has maintained much of its historic character while adapting to the economic and social changes of the modern era.
