Enter the coordinates of 3 different points into the calculator to determine the average distance between those points.

Distance Between 3 Points Formula

The following formula is used to calculate the distance between 3 points.

D = (D1 + D2 + D3) / 3
  • D1 = √[ ( X2-X1)^2 + (Y2-Y1)^2)
  • D2 = √[ ( X3-X1)^2 + (Y3-Y1)^2)
  • D2 = √[ ( X3-X2)^2 + (Y3-Y2)^2)

To calculate the distance between 3 points, calculate the distance between all 3 combination of points, sum these values together, then divide by 3.

Distance Between 3 Points Example

Let’s take a look at an example of how to calculate the distance between 3 points.

  1. First, find the distance between points 1 and 2 using the formula above for D1.
  2. Next, find the distance between points 1 and 3 using the formula above for D2.
  3. Next, find the distance between points 3 and 2 using the formula above for D3
  4. Finally, calculate the average distance between these points using the formula for D.
