Frequently asked questions
Does it work in 3D?
The same averaging applies to a z coordinate; this tool covers 2D.
Is the midpoint on the line?
Yes, it always lies on the segment joining the two points.
What do I need to enter into the Midpoint Calculator?
Just 4 values: x₁, y₁, x₂, y₂. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Midpoint Calculator work out the answer?
The midpoint averages the x coordinates and the y coordinates of the two endpoints. It applies the formula M = ((x₁+x₂)/2, (y₁+y₂)/2) and shows the working so you can check each step by hand.
Is the Midpoint Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
