- Midpoint
- (2.5, 4)
Steps
- Find delta x: 4 - 1 = 3.
- Find delta y: 6 - 2 = 4.
- Use the distance formula: d = sqrt((x2-x1)^2 + (y2-y1)^2).
- The distance is 5 cm.
How to use the Distance Calculator
- Enter the first point as x1 and y1.
- Enter the second point as x2 and y2.
- Press Calculate distance to see distance, delta x, delta y, and midpoint.
- Use examples, recent answers, or copy the result while checking coordinate geometry.

Frequently asked questions
Quick answers about formulas, units, valid measurements, examples, copying, and private in-browser history.
What formula does the Distance Calculator use?
It uses d = sqrt((x2 - x1)^2 + (y2 - y1)^2), the standard distance formula for two points in a plane.
Does it show midpoint?
Yes. It shows midpoint as ((x1 + x2) / 2, (y1 + y2) / 2).
What do the main Distance Calculator inputs mean?
The main inputs are the numbers, operation, mode, or known values the calculator needs. Keep units consistent, enter percentages the way the page label shows, and use the examples as a quick check before trusting the answer.
How should I read the Distance Calculator answer?
Read the headline answer, then check the supporting lines and examples to understand how the calculator got there. If one input changes, rerun the tool and compare the new answer instead of guessing.
What should I double-check before trusting the Distance Calculator?
Check units, signs, rounding, and the selected mode before copying the answer. If the number feels weird, rerun one of the examples first, then put your own values back in slowly.
Can I use negative coordinates?
Yes. Negative x and y values are accepted as long as each coordinate is a valid number.
Should I use this or the Slope Calculator?
Use Distance Calculator for length between points. Use Slope Calculator for steepness, rise, run, and line equations.
What units does the answer use?
The answer uses the unit label you enter. If your coordinates are in meters, the distance is in meters.
Is my distance history private?
Yes. Recent distance answers stay only in the current browser tab while you use the page. They are not sent to a server.
