Measure Distance on a Map
Use this free online map distance calculator to measure the length of a route, trail, property edge, or any custom path by clicking points directly on the map. The total path length updates as you add points, and all calculations happen locally in your browser.
How to measure distance on a map
- Move the map to the area you want to measure.
- Click once to add the starting point.
- Keep clicking to follow the route, trail, or boundary line.
- Read the total distance in the tools panel and use Clear to start over.
If you just need to know how far is it between two places, click once for the start and once for the end.
Best uses
- Estimate walking, hiking, cycling, or running path length.
- Measure the distance between multiple points instead of one straight line.
- Check fence lines, shoreline segments, or rough route alternatives.
Why people use this tool
It works like a simple route distance calculator without requiring an upload, login, or desktop GIS software. You click the map, adjust the path visually, and read the result immediately.
What this tool measures
The measurement follows every segment between the points you place, so it is useful for custom paths, not only for a single straight-line distance.
Units
Distances are displayed in metric and imperial units together, with meters or kilometers plus feet or miles depending on the total length.
Accuracy
Distances are computed using a haversine great-circle formula for each segment. Zoom in and place more points along bends if you want a closer approximation of the real route.
Privacy
This page runs locally in your browser, so you can measure distance on the map without uploading route data or coordinates to a server.
Map Distance Calculator FAQ
How do I measure distance on a map?
Pan or zoom to your area, then click on the map to add each waypoint along the route you want to measure. The tool adds every segment together and shows the total distance in the measurement panel.
How far is it between two points?
To answer “how far is it”, click the map to add a start point and an end point. The distance appears immediately in the tools panel in both metric and imperial units.
Can I measure a route with multiple turns?
Yes. This tool works best when you add several points along a road, trail, shoreline, fence line, or any other path with bends. More points usually produce a closer estimate to the route you want to follow.
What units does the map distance calculator show?
The result is shown in metric and imperial units at the same time. Depending on the total length, you will see meters or kilometers together with feet or miles.
How accurate is the distance measurement?
Distances are calculated from the points you place on the map using great-circle geometry between each point. For better accuracy, zoom in and click more precisely along the real path instead of using only a few broad points.
