Method
Euclidean distance is the square root of the sum of squared coordinate differences: √(Δx² + Δy² [+ Δz²]).

Coordinate Distance Calculator
Measure straight-line distance between two points in two or three dimensions, including deltas, midpoint and direction.
The calculation runs locally. Exact-integer tools avoid floating point; decimal and transcendental tools report rounding limits.

How the Coordinate Distance Calculator works
Euclidean distance is the square root of the sum of squared coordinate differences: √(Δx² + Δy² [+ Δz²]). The calculator keeps the intermediate values visible so you can reproduce the answer independently.
Interpret the result
The midpoint averages each coordinate; the 2D direction uses atan2(Δy, Δx).
Check the assumptions
This is straight-line Cartesian distance, not road distance or distance across Earth's curved surface.
Local calculation
Everything runs in this browser. Inputs are not sent to an external calculator.
Rounding
Displayed values may be rounded for readability while calculations use full floating-point precision unless the tool explicitly uses exact integers.
Scope
This is straight-line Cartesian distance, not road distance or distance across Earth's curved surface.
Simple by design
Three steps to a clearer number.
Enter your details
Use realistic values in each field. You can change them anytime.
Calculate instantly
The formula runs locally, so there is no account or waiting time.
Use the result
Treat the answer as a practical estimate for your next decision.
