Coordinate Midpoint Calculator
The midpoint calculator finds the point exactly halfway between two coordinates and also reports the straight-line distance between the points.
How to use this calculator
- Enter the x and y coordinates of both points. The output gives the midpoint coordinates and point-to-point distance.
- Check the units and definitions before comparing results with another source.
- Change one input at a time when comparing scenarios, and keep the reporting period and assumptions consistent.
Formula used by the coordinate midpoint calculator
M = ((x₁ + x₂)/2, (y₁ + y₂)/2); d = √((x₂ − x₁)² + (y₂ − y₁)²)
- M = ((x₁ + x₂)/2, (y₁ + y₂)/2); d = √((x₂ − x₁)² + (y₂ − y₁)²)
- Coordinates must use the same coordinate system and units. The distance is Euclidean straight-line distance, not road or path distance.
- Inputs are checked for required values and valid ranges; displayed results are rounded for readability.
Worked examples
Worked example
Point A is (2, 4) and point B is (8, 10).
The midpoint is ((2+8)/2, (4+10)/2) = (5, 7); the distance is √72 ≈ 8.485 coordinate units.
The midpoint is ((2+8)/2, (4+10)/2) = (5, 7); the distance is √72 ≈ 8.485 coordinate units.
Understanding the result

Frequently asked questions
Can coordinates be negative?
Yes. Negative coordinate values are valid; the same midpoint formula applies.
Does it calculate travel distance?
No. It measures straight-line coordinate distance and does not account for roads, obstacles or map projections.
How do I use this calculator?
Enter the x and y coordinates of both points. The output gives the midpoint coordinates and point-to-point distance.
