Enter two points to find the midpoint.
How it works
The midpoint formula
The midpoint of a segment is the point exactly halfway between its endpoints. It is found by averaging the coordinates: M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2). The midpoint always lies on the segment and divides it into two equal halves.
Where the midpoint is used
The midpoint is used in geometry to bisect segments, find the center of a circle from a diameter, and locate the centroid of simple shapes. In coordinate geometry it pairs naturally with the slope and distance formulas for the same two points.
Frequently asked questions
›What is the midpoint formula?
M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2) — the average of the x-values and the average of the y-values.
›Is the midpoint always on the segment?
Yes. It lies exactly halfway between the two endpoints and divides the segment into equal halves.
›Can coordinates be negative?
Yes. The formula works with negative numbers, decimals, and zero.
›How is midpoint different from distance?
The midpoint is the center point; the distance is the length between the two points.
›Does order of the points matter?
No. Swapping the two points gives the same midpoint.
