How to use the 3D Midpoint Calculator
The 3D Midpoint Calculator works out your midpoint x, along with 2 related figures in an instant. Enter point 1 — x, point 1 — y and point 1 — z and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.
- Enter the point 1 — x.
- Enter the point 1 — y.
- Enter the point 1 — z.
- Enter the point 2 — x.
- Enter the point 2 — y.
- Enter the point 2 — z.
- Read off your midpoint x, together with midpoint y and midpoint z — the calculator updates automatically, with no button to press.
Formula
The 3D Midpoint Calculator uses the formula:
Midpoint x = (Point 1 — x + Point 2 — x) ÷ 2
Worked example
For example, with point 1 — x of 0, point 1 — y of 0, point 1 — z of 0 and point 2 — x of 10 and the other inputs, the midpoint x is 5.0000.
| Point 1 — x | 0 |
|---|---|
| Point 1 — y | 0 |
| Point 1 — z | 0 |
| Point 2 — x | 10 |
| Point 2 — y | 10 |
| Point 2 — z | 10 |
| Midpoint x | 5.0000 |
|---|---|
| Midpoint y | 5.0000 |
| Midpoint z | 5.0000 |

Frequently asked questions
Average each coordinate: ((x1+x2)/2, (y1+y2)/2, (z1+z2)/2). The midpoint of (0,0,0) and (10,10,10) is (5,5,5).
Yes. Set both z values to zero and use only the x and y results.
It is the point exactly halfway between two points, equidistant from each.
Yes. It lies on the straight segment joining the two points, at its centre.
The 3D Midpoint Calculator uses the formula: Midpoint x = (Point 1 — x + Point 2 — x) ÷ 2. For example, with point 1 — x of 0, point 1 — y of 0, point 1 — z of 0 and point 2 — x of 10 and the other inputs, the midpoint x is 5.0000.
Enter the point 1 — x. Enter the point 1 — y. Enter the point 1 — z. Enter the point 2 — x. Enter the point 2 — y. Enter the point 2 — z. Read off your midpoint x, together with midpoint y and midpoint z — the calculator updates automatically, with no button to press.
