Additional Information:

Whether you are measuring distances for math problems, construction planning, travel routes, or mapping coordinates, calculating the exact distance between two points is a crucial task. Doing this manually using formulas can be time-consuming and prone to mistakes, especially when working with large numbers or 3D space.

Our Distance Calculator instantly computes the distance between two points — whether they are on a flat plane (2D), in space (3D), or even on Earth using latitude and longitude. This makes it a versatile tool for students, engineers, surveyors, travelers, and GIS professionals who need quick, precise answers.

📚 What is Distance?

Distance is the measure of space between two points. In mathematics, it is the length of the straight line joining them.

For two points in 2D space: A(x1,y1),B(x2,y2)A(x_1, y_1), B(x_2, y_2)A(x1,y1),B(x2,y2)

The distance ddd is given by the distance formula: d=(x2−x1)2+(y2−y1)2d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2}d=(x2−x1)2+(y2−y1)2

In 3D space: d=(x2−x1)2+(y2−y1)2+(z2−z1)2d = \sqrt{(x_2 – x_1)^2 + (y_2 – y_1)^2 + (z_2 – z_1)^2}d=(x2−x1)2+(y2−y1)2+(z2−z1)2

For Earth coordinates (GPS latitude/longitude), we use the Haversine formula to account for the planet’s curvature.

📝 How to Use the Distance Calculator

Follow these steps to calculate distance easily:

📊 Distance Calculation Example

Example 1 (2D):
Find distance between A(3,4)A(3, 4)A(3,4) and B(7,1)B(7, 1)B(7,1): d=(7−3)2+(1−4)2=16+9=25=5d = \sqrt{(7-3)^2 + (1-4)^2} = \sqrt{16 + 9} = \sqrt{25} = 5d=(7−3)2+(1−4)2=16+9=25=5

✅ Distance = 5 units

Example 2 (3D):
Find distance between A(1,2,3)A(1, 2, 3)A(1,2,3) and B(4,6,8)B(4, 6, 8)B(4,6,8): d=(4−1)2+(6−2)2+(8−3)2=9+16+25=50≈7.07d = \sqrt{(4-1)^2 + (6-2)^2 + (8-3)^2} = \sqrt{9+16+25} = \sqrt{50} \approx 7.07d=(4−1)2+(6−2)2+(8−3)2=9+16+25=50≈7.07

✅ Distance ≈ 7.07 units

Example 3 (GPS):
Find distance between Paris (48.8566° N, 2.3522° E) and London (51.5074° N, 0.1278° W):

Using Haversine formula:
✅ Distance ≈ 343 km
