Free online 2d and 3d distance between two points calculator using co ordinates.

Distance between two points

This is free online distance formula calculator to calculate the distance between two points given the co ordinates of the distance.

2D distance calculator

In 2 dimensional distance calculator the co ordinates required of two points are along two axes namely X and Y.

The distance formula in 2 dimensional case is given as follow:

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}

Consider following example :

Point 1 –> (1,2)

Point 2 –> (4,5)

d=\sqrt{\left(4-1\right)^{2}+\left(5-2\right)^{2}}d=\sqrt{\left(3\right)^{2}+\left(3\right)^{2}}d=\sqrt{\left(18\right)}

d=4.2426406871

3D distance calculator

In 3 dimensional distance calculator the co ordinates required of 3 points are along 3 axes namely X, Y and Z.

The distance formula in 3 dimensional case is given as follows:

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}+\left(z_{2}-z_{1}\right)^{2}}

Consider following example :

Point 1 –> (1,2,3)

Point 2 –> (4,5,6)

d=\sqrt{\left(4-1\right)^{2}+\left(5-2\right)^{2}+\left(6-3\right)^{2}}

d=\sqrt{\left(3\right)^{2}+\left(3\right)^{2}+\left(3\right)^{2}}

d=\sqrt{\left(27\right)}

d=5.1961524227
