A Township refers to a specific unit of land measurement used predominantly in the United States, within the framework of the Public Land Survey System (PLSS), which originated from the Land Ordinance of 1785. Each township is a square tract of land, typically measuring six miles on each side, amounting to 36 square miles in total. The PLSS is a method of subdividing and describing land to facilitate the clear and organized transfer of property.
Historical Context of Townships
The concept of the township in the PLSS dates back to the late 18th century, following the American Revolution. The Land Ordinance of 1785 aimed to create a systematic and uniform way to survey and parcel out land west of the original thirteen states. Thomas Jefferson proposed a square-mile grid that would facilitate both land sales and easy management, shaping the American landscape through precise measurements and simple land descriptions.
Structure and Types of Townships
Basic Structure
Each township is divided into 36 sections, each one square mile (or 640 acres) in size.

Special Case: Correction Lines
To accommodate the curvature of the Earth, surveyors introduced correction lines (standard parallels) every few townships. These corrections ensure that the consistent six-mile by six-mile grid can be maintained despite the Earth’s curvature.
Applicability and Use Cases
Townships are primarily used for:
- Delineating property boundaries
- Organizing land sales and distribution
- Facilitating infrastructure development, such as roads and utilities
- Agricultural planning and zoning
Comparisons with Other Systems
Metes and Bounds
Unlike the PLSS, the metes and bounds system describes land based on physical landmarks and distance directions, which can often lead to ambiguous boundaries.
Lot and Block System
This system uses recorded plat maps to describe land, primarily used in urban and suburban areas, as opposed to the large, rural tracts detailed by townships in the PLSS.
