2D Distance Calculator
Calculate straight-line Euclidean distance between two points in a plane.
How to use
- Enter x and y for the first point.
- Enter the second point and calculate the distance.
Capabilities and scope
Coordinate differences between (x1,y1) and (x2,y2) are combined with the Pythagorean distance formula.
How it works
It uses d = √[(x2−x1)² + (y2−y1)²].
Example
The distance from (0,0) to (3,4) is 5.
Useful for
- Measure straight-line separation in a Cartesian coordinate system
- Summarize x/y displacement as one distance
Before you use it
- Both axes should use compatible units; Earth curvature and route distance are not included.
Frequently asked questions
Can I use latitude and longitude directly?
Usually no. Geographic coordinates require a spherical or geodesic distance model.
