# 2D Distance Calculator: Straight Line Distance Between Points

Written by:

Here is a 2D distance formula calculator, which will calculate the straight line or Euclidean distance between two points in two dimensions.

## Formula for 2D Euclidean Distance

The formula for two-dimension distance is:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Where:

• d: the distance between the two points (or the hypotenuse)
• x1, y1: the x and y coordinates of point 1
• x2, y2: the x and y coordinates of point 2

### Example Distance Calculation

Let's say you have 2 points, (x, y):

• (4, 9)
• (0, 6)

Here's how you do the math:

d=\sqrt{(0-4)^2+(6-9)^2}=\sqrt{(-4)^2+(-3)^2}=\\=\sqrt{16+9}=\\\sqrt{25}=5

The distance between these points is 5.

## Using the 2D Distance Formula Calculator

First, leave the Dimensions setting at 2.

Next, enter the x, y coordinates of the two points. The top table holds the X & Y for the first point, the lower holds the X & Y for the second.

Now, hit the Compute Distance button and we'll show you the distance – it's that simple. Enjoy!
