Distance Between Two Points
Enter two points and get the distance and midpoint — runs locally, no upload.
How the distance formula works
The Euclidean distance between two points (x₁, y₁) and (x₂, y₂) is calculated using the Pythagorean theorem: distance = √((x₂ − x₁)² + (y₂ − y₁)²). Think of it as the length of the straight line connecting the two points on a grid. The midpoint — the point exactly halfway between them — is ((x₁ + x₂) / 2, (y₁ + y₂) / 2).

FAQ
What is Euclidean distance? It’s the straight-line distance between two points in a plane, computed from the Pythagorean theorem. It’s the most common way to measure how far apart two coordinates are.
How do I find the midpoint? Average the x-coordinates and average the y-coordinates separately. For (0, 0) and (4, 6), the midpoint is (2, 3).
Can I use negative coordinates? Yes. The formula works for any real numbers, including negatives and decimals.
What’s the distance when both points are the same? Zero. The formula correctly returns 0 when all four coordinates are identical.
