Midpoint Between Two Coordinates
Find the exact geographic midpoint between two latitude and longitude points — the spot that sits halfway along the shortest path across the Earth's surface. Perfect for meeting in the middle. Paste decimal degrees, a DMS string, or a Google Maps link for each point and open the result straight in your favourite map.

How the midpoint is calculated
The calculator converts both points to 3-D coordinates on a sphere, finds the true halfway point along the great-circle arc between them, and converts that back to latitude and longitude. This is far more accurate than averaging the two coordinates, which breaks down over long distances and when points straddle the 180° meridian. The result is the same midpoint a navigator or mapping engine would compute.
Frequently asked questions
- How do I find the midpoint between two coordinates?
- Enter both locations into Point A and Point B as decimal degrees, a DMS string, or a Google Maps link. The calculator returns the geographic midpoint in decimal and DMS, and gives you one-click links to open it in Google Maps, Apple Maps, or OpenStreetMap.
- Is this the same as averaging the two latitudes and longitudes?
- No. Simply averaging latitude and longitude is inaccurate over long distances and near the poles or the 180° meridian. This tool computes the true great-circle midpoint — the point that lies exactly halfway along the shortest path across the Earth's surface.
- What is a geographic midpoint useful for?
- The most common use is meeting halfway: two people in different cities can find a fair point between them to meet. It is also handy for choosing a central venue, planning a rendezvous, or finding the centre point between two assets or sensors.
- Does it also tell me the distance?
- Yes. Alongside the midpoint, the calculator shows the total great-circle distance between the two points in kilometres, miles, and nautical miles, plus the initial bearing from Point A to Point B.
