What Is 2D Distance?
In mathematics, 2D distance refers to the shortest distance between two points on a flat (two-dimensional) plane. The points are usually represented using Cartesian coordinates:
Point A (x₁, y₁)
Point B (x₂, y₂)
The distance between them is the length of the straight line connecting the two points.
2D Distance Formula Explained
The formula used to calculate distance in 2D space is derived from the Pythagorean theorem:
Distance = √[(x₂ − x₁)² + (y₂ − y₁)²]
Where:
- x₁, y₁ = coordinates of the first point
- x₂, y₂ = coordinates of the second point
This formula works for all coordinate values—positive, negative, or mixed.

Example Distance Calculation
Example:
Points:
- A (2, 3)
- B (6, 7)
Calculation:
Distance = √[(6 − 2)² + (7 − 3)²]
Distance = √[16 + 16]
Distance = √32
Distance ≈ 5.66
The distance between the two points is approximately 5.66 units.
