What Midpoint Calculator does
Find the spherical midpoint between two coordinates, including antimeridian-safe results.

- Enter two coordinate pairs.
- Calculate the spherical midpoint.
- Copy DD, DMS, GeoJSON, or map links.
Method and calculation
The midpoint is calculated on a sphere using Cartesian components rather than averaging latitude and longitude.

All coordinates and files are processed locally in your browser and are not uploaded.
Limitations
Antipodal points do not have one unique midpoint. Near-antipodal results can be sensitive to tiny input changes.

Frequently asked questions
Why not average the numbers?
Simple averaging fails near the antimeridian and is not a spherical midpoint.
Is the midpoint uploaded?
No. It is calculated locally.
