Find the straight-line distance between two points. Enter the coordinates.
Distance
—
Between the points.Usage Tip
If the points share an x or y value, the distance is just the difference in the other coordinate — no square root needed.
THE MATH
distance = √((x2 − x1)² + (y2 − y1)²)
The Pythagorean theorem on the coordinate plane
The Pythagorean theorem on the coordinate plane
The distance formula is the Pythagorean theorem applied to the horizontal and vertical gaps between two points.
It gives the length of the straight segment joining them.
It gives the length of the straight segment joining them.
Works for any two points in the plane.
The run and rise are the legs of a right triangle; the distance is the hypotenuse.
Distance is always non-negative.
