Quick answer
The distance between two points is √((x₂−x₁)² + (y₂−y₁)²), a direct application of Pythagoras.
d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²)

Frequently asked questions
Is this the same as Pythagoras?
Yes. The distance formula is the Pythagorean theorem applied to the horizontal and vertical differences.
Does it work in 3D?
Yes — just add the z term under the square root, which this calculator does automatically.
