Measure two points

Midpoint Calculator

Give it two latitude, longitude pairs and it returns the exact geographic midpoint — the true halfway point along the curved great-circle line, not a naive average — in decimal degrees and DMS, with the full distance from A to B alongside it.

Great-circle distance; the midpoint is halfway along it

The geographic midpoint along the great-circle path between A and B — not a simple average of the two coordinates. All coordinates use the WGS84 datum.

A Midpoint B

How to find the midpoint between two coordinates

  1. Enter your first point in the Point A field as latitude, longitude in decimal degrees (for example 40.7128, -74.0060). Tap Use my location to fill A with your current GPS position.
  2. Enter your second point in the Point B field the same way, or pick one of the example pairs below.
  3. Read the midpoint instantly in decimal degrees and degrees / minutes / seconds, along with the total great-circle distance between A and B.
  4. Copy the midpoint, open it in Google Maps, or drag marker A or B on the map to recompute the halfway point live. Use Swap to exchange the two points.

What "geographic midpoint" really means

The midpoint reported here lies exactly halfway along the great-circle line — the shortest path across the surface of the Earth — between your two coordinates. It is not the plain average of the two latitudes and longitudes. Averaging holds only for points close together; stretch the pair across a continent, or push it toward a pole or the antimeridian, and a simple average drifts well off the true halfway point. This calculator runs the spherical midpoint formula, the same geodesy navigation relies on, so the figure stays correct even for transcontinental pairs. When you also need the heading or the full distance breakdown, use distance between coordinates.

What the results mean

OutputWhat it is
Midpoint (DD)The geographic midpoint in decimal degrees as latitude, longitude — the halfway point along the great-circle path, on WGS84.
Midpoint (DMS)The same point written in degrees, minutes and seconds with N/S and E/W hemispheres.
Total distanceThe full great-circle distance between A and B, shown in kilometres and miles. The midpoint sits half this distance from each point.
MapA lazy-loaded map marking A, B and the midpoint, joined by the great-circle line. Drag A or B to update everything live.

Accepted coordinate formats

Each field takes decimal degrees split by a comma (51.5074, -0.1278), positive for North and East, negative for South and West. Hemisphere suffixes work too (51.5074N, 0.1278W), as do degrees / minutes / seconds. When you have only your own position, open what are my coordinates to take a GPS reading, then drop it in here. To re-express a point as DMS, UTM, MGRS or a Plus Code first, send it through the coordinate converter.

Frequently asked questions

How is the midpoint calculated?
It is the point exactly halfway along the great-circle (shortest) path between your two coordinates, computed with the spherical midpoint formula on the WGS84 datum. It is not a simple average of the latitudes and longitudes.

Why not just average the two coordinates?
Averaging the latitudes and longitudes is only accurate for points that are close together. Over long distances, near the poles, or across the 180° antimeridian, the average drifts away from the true halfway point — so this tool uses proper great-circle geodesy instead.

What format should I enter the coordinates in?
Decimal degrees as "latitude, longitude" — for example 48.8566, 2.3522. Use negative numbers for South and West, or add N/S/E/W suffixes. Degrees/minutes/seconds also work. Coordinates are read on the WGS84 datum.

Is the total distance straight-line or driving distance?
It is the great-circle, straight-line distance across the surface of the Earth — "as the crow flies" — not a road distance. The midpoint lies exactly halfway along that line. For the full breakdown with bearing, see distance between coordinates.

Can I find a meeting point halfway between two places?
Yes — paste both locations as coordinates and the midpoint is your geographic halfway point. Note it is the halfway point by distance on the map, not by travel time on roads. For named places and travel-time midpoints, try places.app.

Are my coordinates sent anywhere?
No. The midpoint and distance are calculated entirely in your browser. Nothing about your points is uploaded or stored, and the map only loads tiles when you choose to view it.
