Distance between two points calculator
Calculate the straight-line Euclidean distance between two points in a coordinate plane.
How to use this calculator
Enter x₁, y₁, x₂ and y₂. Calculate the straight-line Euclidean distance between two points in a coordinate plane. The answer updates when you change an input.
Understanding the result
The horizontal and vertical differences form the legs of a right triangle, so the Pythagorean theorem gives the direct distance.
