Midpoint Calculator

Midpoint Calculator is part of Toolspire and is ready as soon as this page loads. Each coordinate is averaged on its own. The midpoint is not the same as a weighted centre, and it is not the slope.

What you can do here

X and y are averaged separately

You do not average all four numbers into one.

Order does not matter

The same two points in either order share a midpoint.

The sample is the check

(1, 2) is halfway from the origin to (2, 4).

How to use the Midpoint Calculator

  1. 1

    Type both endpoints

    A midpoint needs two points. One point is already its own middle.

  2. 2

    Read the pair

    The headline is x, then y, in parentheses.

  3. 3

    Use slope if you wanted steepness

    The midpoint does not tell you the gradient.

Worth knowing

  • Midpoint Calculator on Toolspire: midpoint = ((x1+x2)/2, (y1+y2)/2).
  • (0, 0) and (2, 4) meet at (1, 2).
  • The two halves of the segment are equal in length. That is what averaging coordinates guarantees.
  • A weighted midpoint, closer to the heavier end, is not this formula.

Halfway in each coordinate

The midpoint of a segment in the plane is the average of the x coordinates and the average of the y coordinates. From (0, 0) to (2, 4) those averages are 1 and 2. The point (1, 2) is equidistant from the ends along the segment. It is not the average of the slopes, and it is not pulled toward a point you consider more important.

FAQ

Questions about Midpoint Calculator

Where does Midpoint Calculator run?

Midpoint Calculator runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

What is the midpoint of (0, 0) and (2, 4)?

(1, 2).

Does order matter?

No. Averaging is commutative.

Is this the centroid of a triangle?

No. A triangle needs three vertices. This page averages two.

Can the coordinates be negative?

Yes. The average of −2 and 4 is 1, the same arithmetic.
