Distance Between Two Points Calculator
Enter the (x, y) coordinates of two points to find the straight-line distance between them using the distance formula.
Distance Between Two Points Calculator
Calculates the straight-line distance between two points on a coordinate plane.
This calculator finds the straight-line (Euclidean) distance between two points on a 2D coordinate plane using the distance formula, which is just the Pythagorean theorem applied to the horizontal and vertical differences between the points. It's a standard tool for geometry homework, graphics/game programming coordinate math, or GIS-style planar distance checks where coordinates are already on a flat plane rather than the curved surface of the earth.
Example
- With the default values shown above, this calculator returns: Distance ≈ 5.
Frequently Asked Questions
What formula is used?
The distance formula, derived from the Pythagorean theorem: d = √((x₂-x₁)² + (y₂-y₁)²).
Do the coordinates need units?
No, the calculator works with plain numeric coordinates; the result is in whatever unit your coordinates are already expressed in.
