Online Distance Calculator
Calculate the distance between two points in 2D or 3D, or the great-circle distance between two latitude/longitude locations, with one-click copy.
Result
d = 26.19637
What Is This Tool?
The Advanced Distance Calculator finds the distance between two points in three different modes. In 2D mode it uses the distance formula on X and Y coordinates. In 3D mode it adds a Z coordinate for points in space. In geographic mode it uses the Haversine formula to find the great-circle distance between two latitude/longitude locations, shown in both kilometers and miles. Results are rounded to five decimals, and you can copy them with one click.
How to Use This Tool?
- Choose a mode: 2D, 3D, or latitude/longitude.
- Enter the coordinates for both points.
- Click Calculate to get the distance.
- Click the copy icon to copy the result.
Key Features
- Three modes: 2D, 3D, and latitude/longitude.
- Uses the distance formula for 2D and 3D points.
- Calculates great-circle distance with the Haversine formula.
- Shows geographic distance in both kilometers and miles.
- Includes a one-click copy button for the result.
Examples
- In 2D, the distance from (0, 0) to (3, 4) is 5.
- In 3D, the distance from (0, 0, 0) to (1, 2, 2) is 3.
- In 2D, the distance from (-7, -4) to (17, 6.5) is about 26.19637.
- In geographic mode, two latitude/longitude points return a distance in both kilometers and miles.
Common Use Cases
- Measuring distance between points on a coordinate plane.
- Finding the distance between two points in 3D space.
- Estimating real-world distance between two map locations.
- Checking geometry and physics homework answers.
- Comparing straight-line and great-circle distances.
Tips & Best Practices
- Pick the mode that matches your data before entering values.
- Keep latitude between -90 and 90 and longitude between -180 and 180.
- Use a minus sign for negative coordinates and a dot for decimals.
- Remember geographic mode gives the great-circle distance, not a road route.
- Copy the result directly to avoid transcription mistakes.
Limitations
- Calculates the distance between exactly two points at a time.
- Geographic mode assumes a spherical Earth, so it is a close approximation.
- Results are rounded to five decimal places.
- Geographic distance is straight-line over the surface, not a travel route.
Frequently Asked Questions
- What is the difference between the modes?
- 2D and 3D use the straight-line distance formula on coordinates, while geographic mode uses the Haversine formula for distance over the Earth's surface.
- Why does geographic mode show two numbers?
- It reports the distance in both kilometers and miles so you can use whichever unit you prefer.
- Is the geographic distance exact?
- It is a close approximation. The Haversine formula treats the Earth as a perfect sphere, which introduces a small error.
- Can I use negative coordinates?
- Yes. 2D and 3D accept any numbers, and geographic mode accepts negative latitude and longitude within the valid ranges.
Key Terminology

- Great-circle distance
- The shortest distance between two points measured over the surface of a sphere.
- Haversine formula
