How to use this tool

  1. Enter first point: x, first point: y, second point: x, second point: y.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Distance = square root of ((x₂ − x₁)² + (y₂ − y₁)²). The midpoint averages the two x coordinates and the two y coordinates separately.

A WORKED EXAMPLE

The points (0, 0) and (3, 4) are 5 units apart. Their midpoint is (1.5, 2).

What to keep in mind

For Cartesian coordinates with the same scale on both axes. Geographic latitude and longitude require a geodesic calculation; road distance is not modeled.

Common questions

Can I enter negative coordinates?

Yes. Each coordinate may be positive, zero or negative.

What if both points are the same?

Their distance is zero and the midpoint is the point itself.
