Distance Between Two Points Calculator
Calculate straight-line distance between two coordinates.
Inputs and results stay in this browser. Change one value at a time to explore the relationship.
Calculation steps
- Horizontal change = 3; vertical change = 4.
- Square and add: 9 + 16 = 25.
- Take the square root: d = 5.
Definition and formula
Coordinate distance is the hypotenuse of a right triangle formed by the horizontal and vertical differences.
d = √[(x₂ − x₁)² + (y₂ − y₁)²]
Worked example
From (1, 2) to (4, 6), d = √(3² + 4²) = 5.
Common mistake
Square both coordinate differences before adding them.
How to learn with this calculator
Begin with the worked example, then change one value while keeping the others fixed. Compare the new result and calculation steps to identify which part of the formula changed.
