Midpoint calculator

Type any city or country, or click two points on the map. The calculator finds the true halfway point along the shortest route on the globe.

Or click the map: the first click sets From, the next sets To. Countries are measured from their capital city.

How the midpoint is calculated

The calculator converts both places to points on a sphere and takes the point halfway along the great circle that joins them. That is the midpoint of the shortest possible path, the one long-haul flights approximate. It is not the average of the two latitudes and longitudes, which is what many simple tools return and which can be thousands of kilometres off for long routes.
