Distance Between Two Points
Enter two (x, y) points to get the straight-line distance between them.
Straight-line distance on a plane
The distance between two points is a fundamental measurement in geometry, graphics, and games. Enter the coordinates of both points and this returns the straight-line distance plus the horizontal and vertical gaps that make it up.
From (0, 0) to (3, 4) the distance is exactly 5, because the differences of 3 and 4 form a right triangle. Seeing Δx and Δy separately also gives you the run and rise for a slope.

Frequently Asked Questions
What formula is used?
The distance formula, √((x₂−x₁)² + (y₂−y₁)²), which is the Pythagorean theorem applied to the horizontal and vertical differences.
Does it show the axis gaps?
Yes — it reports Δx and Δy alongside the distance, which is useful for slopes, vectors, and bounding boxes.
Can I use negative coordinates?
Yes. Any real numbers work, including negatives and decimals.
