Midpoint Calculator – 2D and 3D
Find the point halfway between two Cartesian coordinates.
Formula
M = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2).
Midpoint x ≈ ((1)+(5))÷2 · Midpoint y ≈ ((2)+(8))÷2 · Midpoint z ≈ ((0)+(0))÷2
How to use
- Enter the first endpoint.
- Enter the second endpoint in the same coordinate system.
- Read the midpoint coordinates.
Examples
- (1, 2) and (5, 8) have midpoint (3, 5).
Frequently asked questions
How do I use 2D coordinates?
Set z₁ and z₂ to zero; read the x and y results.
Are negative coordinates allowed?
Yes. Keep all coordinates in the same Cartesian system and unit.
What if both endpoints match?
The midpoint is that same point.
