The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- x = (x₁ + x₂) ÷ 2 = (1 + 7) ÷ 2 = 4.
- y = (y₁ + y₂) ÷ 2 = (2 + 10) ÷ 2 = 6.
| Inputs | Answer |
|---|---|
| x₁: 1; y₁: 2; x₂: 7; y₂: 10 | The midpoint is (4, 6). |
| x₁: -3; y₁: 4; x₂: 5; y₂: -2 | The midpoint is (1, 1). |
How to use it
The midpoint of the segment from (x₁, y₁) to (x₂, y₂) is the average of the coordinates: ((x₁ + x₂) ÷ 2, (y₁ + y₂) ÷ 2). The midpoint of (1, 2) and (7, 10) is (4, 6).
The distance between the points is shown as well, so you can see that each half has half that length.
Frequently asked questions
How do I find the midpoint of two points?
Average the x values and average the y values.
What is the midpoint of (1, 2) and (7, 10)?
(4, 6).
How do I find an endpoint from the midpoint?
Double the midpoint and subtract the known endpoint: x₂ = 2xₘ − x₁.
