Distance Between Two Points in 2D
Calculate the straight-line (Euclidean) distance between any two points in a 2D coordinate plane. Used in geometry, game development, GPS calculations, and physics.
Formula
Distance = √((x₂ − x₁)² + (y₂ − y₁)²). This is the Pythagorean theorem applied to the horizontal and vertical differences between the points.
Worked example
Point 1 (0, 0), Point 2 (3, 4): distance = √(9 + 16) = √25 = 5. This is the classic 3-4-5 right triangle.
Practical guidance
Application in graphics and games
Distance between points is used in collision detection, camera positioning, spatial queries, and pathfinding algorithms. The distance formula works in any coordinate system as long as axes are perpendicular.
Negative coordinate values
The formula squares the differences, so negative inputs produce correct results. Point (−2, −3) to (4, 5): differences are 6 and 8, distance = √(36 + 64) = 10.
Frequently asked questions
What formula does this calculator use?
Distance = √((x₂-x₁)² + (y₂-y₁)²)
Can I use decimal values?
Yes. Decimal inputs are supported for most calculators. Integer-based tools use rounded integer values where appropriate.
