Midpoint Calculator - Find the Midpoint Between Two Points

Find the Midpoint Between Two Points

This midpoint calculator finds the exact center point between two coordinates on a plane. Enter the x and y values for both points and it instantly returns the midpoint — the point that sits exactly halfway along the line segment joining them.

The midpoint formula M = ((x₁ + x₂)/2, (y₁ + y₂)/2) simply averages the two x-coordinates and the two y-coordinates separately.

Common Use Cases

Geometry

Find the center of a line segment, bisect a shape, or locate a point equidistant from two vertices.

Navigation

Pinpoint the halfway location between two places to choose a fair meeting point.

Computer Graphics

Center objects, align elements, or place pivot points between two coordinates on screen.

How to Calculate the Midpoint

Enter the First Point

Type the x-coordinate (x₁) and y-coordinate (y₁) of the first point into the input fields.

Enter the Second Point

Type the x-coordinate (x₂) and y-coordinate (y₂) of the second point. Negative numbers and decimals are supported.

Midpoint Formula & Tool Features

The Midpoint Formula

The midpoint M between point P₁(x₁, y₁) and point P₂(x₂, y₂) is found by averaging each coordinate independently.

Step	Expression
Midpoint x-coordinate	`xₘ = (x₁ + x₂) / 2`
Midpoint y-coordinate	`yₘ = (y₁ + y₂) / 2`
Midpoint (M)	`M = (xₘ, yₘ)`

Worked example: For points (0, 0) and (4, 6): xₘ = (0 + 4)/2 = 2 and yₘ = (0 + 6)/2 = 3, so the midpoint is (2, 3).

What the Tool Shows

Instant Midpoint

The center coordinate is computed immediately using the standard midpoint formula.

Step-by-Step Solution

A clear breakdown of how each coordinate average is calculated.

Interactive Graph

A graph plots both endpoints and the midpoint that lies between them.

Distance to Endpoints

Shows the distance from the midpoint to each endpoint, which are always equal.

Reference results: (0, 0) and (4, 6) → (2, 3); (−2, 3) and (4, −1) → (1, 1); (1, 5) and (7, 5) → (4, 5).

Frequently Asked Questions

What is the midpoint formula?

The midpoint formula is M = ((x₁ + x₂)/2, (y₁ + y₂)/2). It averages the two x-coordinates and the two y-coordinates separately to give the point exactly halfway between the two endpoints.

How do you find the midpoint of a line segment?

Add the two x-coordinates of the endpoints and divide by 2 to get the midpoint's x-value, then do the same with the two y-coordinates for its y-value. Enter both endpoints above and the calculator does this instantly and shows every step.

What is a midpoint?

A midpoint is the point that lies exactly halfway between two other points — it divides the line segment joining them into two equal parts and is equidistant from both endpoints.

Can I use negative or decimal coordinates?

Yes. The calculator accepts any real numbers, including negative values and decimals. For example, the midpoint of (−2, 3) and (4, −1) is (1, 1).

Is the midpoint always halfway between the points?

Yes. By definition the midpoint is equidistant from both endpoints, so the distance from the midpoint to each point is exactly the same — the tool displays both distances to confirm this.

What is the midpoint used for?

Midpoints appear in geometry, navigation, and computer graphics — for example finding the center of a line segment, choosing a fair meeting point between two places, or aligning objects on a screen.
