About this calculator
The midpoint of a line segment is the point exactly halfway between its two endpoints. To find it, you average the x-coordinates and average the y-coordinates: M = ((x₁ + x₂) ÷ 2, (y₁ + y₂) ÷ 2). The result is a single coordinate pair that lies on the segment and divides it into two equal halves.
The midpoint formula is essential in geometry for finding centers of segments, the center of a circle from a diameter, or the balance point between two locations. It works for any real coordinates and is symmetric — swapping the two points gives the same midpoint.
Frequently asked questions
Add the two x-coordinates and divide by 2 to get the midpoint x, then do the same with the y-coordinates. The pair (avg x, avg y) is the midpoint.
Yes. The midpoint lies exactly halfway along the straight segment connecting the two points, splitting it into two equal pieces.
Yes. If you know the midpoint and one endpoint, double the midpoint coordinate and subtract the known endpoint coordinate to find the other endpoint.
