About the Distance Calculator
Find the straight-line (Euclidean) distance between two points on a plane. Enter the coordinates of both points and the calculator applies the distance formula — √((x₂−x₁)² + (y₂−y₁)²) — to return the distance. It's a fundamental geometry and graphing tool derived directly from the Pythagorean theorem.
How to use the Distance Calculator
- 01Enter your two coordinate points.
- 02Read the result instantly — it recalculates as you type.
- 03Adjust the numbers to model different scenarios.
Frequently asked questions
What is the distance formula?
Distance = √((x₂ − x₁)² + (y₂ − y₁)²), a direct application of the Pythagorean theorem to coordinates.
Does this work in 3D?
This tool is for 2D points. For 3D, add the z-difference squared under the root.
