Distance Between Points Calculator
Distance Between Points: it uses the distance formula d = √((x₂−x₁)² + (y₂−y₁)²) to find the straight-line distance between two points. Worked through below with real figures, and the calculator repeats the working on your own inputs — free, on-device, instant.
Enter your point A — x, point A — y, point B — x and point B — y and Distance Between Points Calculator works out the straight-line distance with the distance formula √((x₂−x₁)²+(y₂−y₁)²) — fast, free and private, with no sign-up or uploads.
About this calculator
It uses the distance formula d = √((x₂−x₁)² + (y₂−y₁)²) to find the straight-line distance between two points. It matters whenever a shape has to be measured, cut, covered or compared and the geometry has to be right first. Worked below as Distance between (1, 2) and (4, 6): √((4−1)² + (6−2)²) = √(9+16) = √25 = 5 . — and the calculator on this page repeats exactly that working for your inputs, instantly, and offline after load.
How to use
- Enter the first point's x and y values.
- Enter the second point's x and y values.
- Press Calculate to find the distance.
- Read the straight-line distance and the change in x and y.

Technical notes
Distance Between Points Calculator uses the distance formula d = √((x₂−x₁)² + (y₂−y₁)²) to find the straight-line distance between two points.
Points are taken exactly as entered on a flat plane; rounding affects only the displayed decimals.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
FAQ
How is the distance between two points calculated?
It uses the distance formula, the square root of the squared change in x plus the squared change in y.
Does the order of the two points matter?
No. The distance is the same whichever point you enter first.
What are the delta x and delta y values?
They are the horizontal and vertical gaps between the points, the building blocks of the distance formula.
Does the Distance Between Points Calculator send my data to a server?
No. The Distance Between Points Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Distance between (1, 2) and (4, 6): √((4−1)² + (6−2)²) = √(9+16) = √25 = 5.
