About the Distance Calculator
This tool measures the straight-line (as-the-crow-flies) distance and the walking/driving path distance between two or more points on a map using GPS coordinates.
It's useful for estimating fence line lengths, trail distances, property boundary runs, or any measurement where you need an accurate distance without physically walking it.
How It Works
Common Use Cases
- ✓ Fence Lines — Measure the total length of a proposed or existing fence run
- ✓ Trail Planning — Estimate hiking, biking, or ATV trail distances
- ✓ Property Boundaries — Check the length of a boundary line between survey markers
- ✓ Irrigation Runs — Plan pipe or hose length for drip and sprinkler systems
- ✓ Construction Layout — Measure distances between structures or site features
Accuracy Information
Distance calculations use the great-circle (haversine) formula for GPS coordinates, which is accurate to within a few feet for most real-world distances.
GPS accuracy on mobile devices is typically 3-5 meters under open sky, and can be less precise near tall buildings, dense tree cover, or indoors.
Frequently Asked Questions
How accurate is the distance calculator?
Distances are calculated using precise GPS coordinate math and are typically accurate to within a few feet, limited mainly by your device's GPS accuracy (usually 3-5 meters).
Can I measure a path with multiple points?
Yes — add as many points as you need. The tool sums the distance between each consecutive point for a running total.
What units does the distance calculator support?
You can switch between feet, meters, yards, miles, and kilometers at any time.
Does this measure straight-line or path distance?
It measures the distance along the path you draw, point to point — not necessarily a straight line unless you only place two points.
Need to Measure Larger Areas?
Use LandLens to measure field boundaries and areas with GPS precision, not just distances.
