Easement & Right-of-Way Area Estimator
Estimate the surface area of easements and right-of-way corridors by entering length and width for each segment. See total area in square feet, acres, and more.
For Planning & Education Only
This tool provides approximate area estimates using simple geometry. It is NOT a legal survey, property description, or engineering design. For official easement documents, consult licensed surveyors and legal professionals.
Enter corridor dimensions to estimate easement/right-of-way area.

Ask things like: “How many acres is this plot if I only know the square feet?”, “What is the area of my land if it’s 60 ft by 90 ft?”, “Can you estimate the area of this irregular plot from these corner coordinates?”, or “How much total fence length do I need to go all the way around this boundary?”.
This AI is experimental and may be inaccurate. Always confirm land area, boundary lengths, and unit conversions with official survey documents, government records, or a licensed land surveyor before relying on them for property, legal, construction, or financial decisions.
Understanding Easements and Rights-of-Way
What Is an Easement or Right-of-Way?
An easement is a legal right to use someone else's land for a specific purpose. A right-of-way is a type of easement that grants passage across property. These are not ownership transfers—they are limited use rights that allow access or utility placement without full ownership.
Common examples include utility easements (for power lines, water pipes, or gas mains), access easements (for driveways or roads), and conservation easements (for environmental protection). Understanding the surface area affected by these easements helps property owners and developers plan accordingly.
How This Easement Area Estimator Works
This tool calculates easement area using simple rectangular geometry. For each corridor segment, you enter:
- Length: The distance along the corridor (e.g., how far the easement runs)
- Width: The width of the corridor (e.g., a 20-foot utility easement)
The tool multiplies length × width for each segment, converts to your preferred units, and sums all segments to give a total easement area. If you provide the total parcel area, it also calculates what percentage of your property is affected.
Common Use Cases
Utility Corridors
Power lines, underground cables, water mains, sewer lines, and gas pipelines typically require easements ranging from 10 to 100+ feet wide depending on the utility type and local regulations.
Access Driveways
Shared driveways and private road easements allow passage to landlocked parcels. Width varies from 12-24 feet for residential access to wider for commercial use.
Pipeline Rights-of-Way
Oil and gas pipelines require permanent easements, often 50-75 feet wide, plus temporary construction easements that may be even wider.
Drainage & Conservation
Stormwater drainage easements, creek setbacks, and conservation easements protect natural features and may restrict development within their boundaries.
Units and Conversions
This tool supports common length units (feet, meters, yards, kilometers) and area units (square feet, square meters, acres, hectares). Here are some useful conversion factors:
- 1 acre = 43,560 square feet
- 1 hectare = 10,000 square meters = 2.471 acres
- 1 square meter = 10.764 square feet
- 1 foot = 0.3048 meters
Limitations: Not a Legal Survey or Property Description
This tool provides approximate estimates only. It assumes simple rectangular corridors and relies entirely on user-entered dimensions. Real easements often have:
- Irregular boundaries following terrain or property lines
- Curved paths that don't match rectangular geometry
- Legal descriptions with specific metes and bounds
- Variations based on recorded plats and survey monuments
For any legal, financial, or construction purpose, you must obtain an official survey from a licensed land surveyor and consult with legal professionals.
