Measure the straight line distance between two points in three dimensional space. The 3D distance formula extends the flat version by adding a z term, so the distance is the square root of the sum of the squared differences in x, y and z. For points at 1, 2, 3 and 4, 6, 15 the distance is 13 units. This calculator also shows the midpoint of the segment, the average of each coordinate pair, which is useful for centering objects or finding balance points. Three dimensional distance appears in graphics, robotics, physics, gaming and navigation whenever height or depth matters, not just a flat map. Enter the six coordinates in any consistent unit and the distance and midpoint return in that same unit. All of the arithmetic runs locally in your browser at full floating point precision with nothing sent to a server, and you can copy the distance with a single click.
It extends the distance formula to three axes, taking the square root of the squared differences in x, y and z added together.
It adds a third z coordinate, so it measures straight-line distance through space rather than across a flat plane.
Yes. Negative x, y or z values work because each difference is squared.
