MeasureMaps is a free online distance calculator for maps. Search any address, click two or more points, and instantly see the distance between them measured along the shortest Great-circle path. Switch between metric, imperial, and nautical units, and export your route to GeoJSON, KML, CSV, or JSON.

Measuring distance takes three clicks:
Distance measurements support three unit systems, so you can work the way you think. Metric shows meters and kilometers, imperial shows feet and land miles, and nautical shows nautical miles — handy for maritime and aviation planning. Switch units any time from the measurement tool.
Straight lines on a flat map are misleading because they ignore the Earth’s curvature. MeasureMaps draws each segment as a Great-circle arc — the true shortest path across the planet’s surface — so distances and bearings stay realistic even over long spans and at high latitudes.
A map distance calculator is useful for far more than a single line:
Select the distance tool, click the first point, then click the second point. MeasureMaps shows the distance instantly. Add more points to measure a multi-stop route and see the total length update as you go.
MeasureMaps measures the Great-circle (as-the-crow-flies) distance along the shortest path across the Earth’s surface, not driving distance along roads. This is ideal for straight-line distance, flight distance, and boundary lengths.
Kilometers and meters (metric), miles and feet (imperial), or nautical miles. You can switch units at any time, and the measurement updates immediately.
