Point Distance Calculator – Find Distance Between Two Points Instantly

This tool not only saves time but also reduces calculation errors, making it perfect for learners, professionals, and hobbyists alike.

What is a Point Distance Calculator?

A Point Distance Calculator is an online tool that helps you calculate the shortest straight-line distance between two points in a two-dimensional Cartesian plane. By simply entering the X and Y coordinates of Point 1 and Point 2, the tool automatically applies 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

Where:

(x1,y1)(x_1, y_1)(x1,y1) = Coordinates of the first point
(x2,y2)(x_2, y_2)(x2,y2) = Coordinates of the second point
ddd = Distance between the two points

This formula is based on the Pythagorean Theorem, making it universally accurate for any two points in a plane.

How to Use the Point Distance Calculator

Using this calculator is extremely easy and straightforward. Just follow these steps:

Enter the first point (X1, Y1):
Input the X and Y values of the first point in the provided fields.
Enter the second point (X2, Y2):
Input the X and Y values of the second point.
Click “Calculate”:
The tool instantly computes the distance between the two points using the formula.
View the Result:
The calculated distance will appear in the result section, displayed up to two decimal places.
Click “Reset” (Optional):
Use the reset button to clear inputs and start a new calculation.

Example of Distance Calculation

Let’s look at an example to understand how it works:

Point 1 = (3, 4)
Point 2 = (7, 1)

Step 1: Subtract the coordinates:

dx=7−3=4dx = 7 – 3 = 4dx=7−3=4
dy=1−4=−3dy = 1 – 4 = -3dy=1−4=−3

Step 2: Square the differences:

dx2=16dx^2 = 16dx2=16
dy2=9dy^2 = 9dy2=9

Step 3: Add and take the square root:

d=16+9=25=5d = \sqrt{16 + 9} = \sqrt{25} = 5d=16+9=25=5

✅ The distance between Point (3,4) and Point (7,1) is 5 units.

When you enter the same values in our Point Distance Calculator, you’ll get the same result instantly.
