How to use this calculator
- Enter the x, y, z of both points.
- Read the distance.
How it works
Distance = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²) — Pythagoras extended to three dimensions.
Worked example
(0,0,0) to (1,2,2). = 3.
Common mistakes
- Forgetting the z term — that gives the 2D distance, not 3D.
- Swapping coordinates between the two points.
Frequently asked questions
Does this work in 2D?
Yes — set both z values to 0 and it reduces to the standard 2D distance.
