Quarter Section Acreage? The Ultimate Land Guide! 🤯

Understanding land division is fundamental in real estate and agriculture. The U.S. Public Land Survey System (PLSS), an important land surveying system, significantly impacts land ownership across many states. The concept of Townships, which are six-mile square grids within the PLSS, provides the framework for defining smaller parcels like sections and quarter sections. Knowing how many acres is a quarter section is crucial for land valuation. Land Surveyors utilize various tools and techniques for these calculations. This guide aims to provide a comprehensive understanding of quarter section acreage.

Understanding Quarter Sections and Acreage: A Comprehensive Guide
This guide provides a clear explanation of quarter sections in land measurement and how to determine their acreage. The primary focus is answering the question: "how many acres is a quarter section?"
The Foundation: Section, Township, and Range
Before diving into quarter sections, it’s essential to understand the broader system of land division used in many parts of the United States and Canada. This system involves sections, townships, and ranges.
-
Section: A section is a square parcel of land measuring one mile by one mile.
-
Township: A township is a larger square composed of 36 sections, arranged in a 6x6 grid. Therefore, a township measures six miles by six miles.
-
Range: Ranges are used to further delineate land areas relative to a principal meridian.
Understanding these terms establishes the context for understanding how quarter sections fit into the larger picture.
Defining the Quarter Section
A quarter section, as the name suggests, is simply a section divided into four equal parts. This creates four smaller, square parcels of land.
How Many Acres is a Section?
Since a section is one mile by one mile, and one mile equals 5280 feet, a section contains:
- 5280 feet x 5280 feet = 27,878,400 square feet
To convert square feet to acres, we use the conversion factor: 1 acre = 43,560 square feet.
- 27,878,400 square feet / 43,560 square feet/acre = 640 acres
Therefore, a section contains 640 acres.
Calculating the Acreage of a Quarter Section
Now, answering the core question: how many acres is a quarter section? Since a quarter section is one-fourth of a section, we simply divide the acreage of a section by four.
- 640 acres / 4 = 160 acres
Therefore, a quarter section contains 160 acres.
Common Variations and Further Divisions
While a standard quarter section is 160 acres, variations can occur due to factors like:

- Irregular Sections: Some sections are not perfect squares due to surveying errors, natural boundaries (rivers, lakes), or previous land grants. These irregularities often affect the acreage of quarter sections within those sections.
- Government Lots: Land along bodies of water or other irregular boundaries may be divided into "government lots" which are not uniform in size.
Dividing the Quarter Section
Quarter sections can be further divided into smaller parcels. The most common divisions are:
- Half-Quarter: Dividing a quarter section in half results in two 80-acre parcels.
- Quarter-Quarter: Dividing a quarter section into quarters results in four 40-acre parcels. This is often referred to as a "forty."
The following table summarizes these divisions:
Land Division | Description | Approximate Acreage |
---|---|---|
Section | 1 mile x 1 mile | 640 acres |
Half Section | Section divided in half | 320 acres |
Quarter Section | Section divided into four equal parts | 160 acres |
Half-Quarter Section | Quarter section divided in half | 80 acres |
Quarter-Quarter Section | Quarter section divided into four equal parts | 40 acres |
Legal Descriptions and Identifying Quarter Sections
Land deeds and legal descriptions precisely identify land parcels, including quarter sections. A typical legal description might look like this:
"The Northwest Quarter (NW 1/4) of Section 12, Township 3 North, Range 2 West of the Principal Meridian."
This description tells you:
- NW 1/4: The parcel is the northwest quarter of the section.
- Section 12: The parcel is located within Section 12.
- Township 3 North: The township is located 3 townships north of a designated baseline.
- Range 2 West: The range is located 2 ranges west of a designated principal meridian.
- Principal Meridian: References the governing meridian for the location.
By interpreting these descriptions, you can pinpoint the specific quarter section on a map or plat.

Quarter Section Acreage FAQs
This section answers common questions about quarter sections of land, as discussed in "Quarter Section Acreage? The Ultimate Land Guide! 🤯".
What exactly is a quarter section?
A quarter section is a standard unit of land measurement derived from the Public Land Survey System (PLSS) used in the United States and Canada. It represents a quarter of a square mile section.
How many acres is a quarter section?
A quarter section contains 160 acres. This is because a section is defined as one square mile, which equals 640 acres. Therefore, a quarter section, being one-fourth of that, equals 160 acres.
Are all quarter sections perfectly square and exactly 160 acres?
While theoretically square, quarter sections can vary slightly due to surveying errors, natural features, or governmental adjustments. These variations are often noted on official plats and may result in slight deviations from the exact 160-acre measurement.
What information do I need to identify a specific quarter section?
To identify a specific quarter section, you typically need its location within a section, township, and range, as defined by the PLSS. This information can usually be found on property deeds or county assessor records.
