How to use this tool?
This calculator computes the Euclidean distance between two points in 2D or 3D space.
- Enter Point A coordinates — Fill in X1 and Y1 (required). Optionally enter Z1 for 3D.
- Enter Point B coordinates — Fill in X2 and Y2 (required). Optionally enter Z2 for 3D.
- Click "Calculate Distance" — The result appears below with the formula used.
- Interpret the result — Distance is shown to 4 decimal places. The formula shows step-by-step calculation.
Note: All coordinates accept any real numbers (positive, negative, decimals). Leave Z fields empty for 2D calculation. The calculator automatically detects 2D or 3D based on whether both Z values are provided.

Frequently Asked Questions
Enter X and Y coordinates for both points. Leave Z fields empty. The calculator will use the formula √((x2-x1)² + (y2-y1)²).
Enter X, Y, and Z coordinates for both points. All six fields must be filled. The calculator will use the formula √((x2-x1)² + (y2-y1)² + (z2-z1)²).
The calculator will display an error message. Ensure all required fields contain valid numbers. Z fields can be left empty for 2D calculations.
