Distance Calculator
Calculate distance between two points
This calculator finds the distance between two points in a 2D coordinate system using the distance formula.
About this Tool
The distance calculator uses the Pythagorean theorem to find the straight-line distance between two points in a 2D coordinate system. This fundamental mathematical tool is essential in geometry, physics, navigation, and computer graphics. By inputting the x and y coordinates of two points, you instantly get the precise distance between them. This calculation is the foundation for countless real-world applications, from mapping and GPS navigation to game development and data analysis.
Common Use Cases
Mathematics & Education
Learn coordinate geometry, practice distance formula problems, verify homework solutions, or visualize spatial relationships between points.
Navigation & Mapping
Calculate straight-line distances on maps, estimate travel distances, or plan optimal routes between locations on a coordinate grid.
Computer Graphics & Gaming
Calculate distances between objects in games, detect collisions, implement AI pathfinding, or measure screen coordinate separations.
Data Analysis & Statistics
Compute distances between data points in 2D space, identify clusters, perform proximity analysis, or calculate Euclidean distances in datasets.
Pro Tips
- !
Understanding Coordinates
Coordinates are written as (x, y). The x-coordinate shows horizontal position, and y-coordinate shows vertical position. Negative values are allowed and indicate direction.
- !
The Pythagorean Connection
The distance formula is derived from the Pythagorean theorem (a² + b² = c²). The horizontal and vertical distances form the legs, and the diagonal distance is the hypotenuse.
- !
Units Don't Matter
As long as both points use the same units (pixels, meters, miles, etc.), the calculation works. The result will be in the same units as your input.
- !
Zero Distance
If the calculated distance is zero, it means both points are at the exact same location - they have identical coordinates.
