Distance Formula Calculator

Distance between two points as an exact square root and decimal with steps.

Quick answer

How do you find the distance between two points?

Subtract the x-values and the y-values, square both, add them, and take the square root. For (1, 2) and (4, 6): √(3² + 4²) = √25 = 5.

d = √((x₂ − x₁)² + (y₂ − y₁)²)

Answer
Distance = 5
  1. d = √((x₂ − x₁)² + (y₂ − y₁)²)
  2. x₂ − x₁ = 4 − (1) = 3 • y₂ − y₁ = 6 − (2) = 4
  3. d = √(3² + 4²) = √(9 + 16) = √25
  4. Simplified: √25 = 5 ≈ 5

Find the distance between two points (x₁, y₁) and (x₂, y₂) as an exact square root and a decimal, with every step.

Is the Distance Formula Calculator free?

Yes. The Distance Formula Calculator is free to use on Fast Online Calculator and does not require an account.

Is the distance formula the Pythagorean theorem?

Yes. The horizontal and vertical gaps are the legs of a right triangle, and the distance is the hypotenuse.

Can distance be negative?

No. Squaring removes negative signs, so distance is always 0 or more.

Does the order of the points matter?

No. (x₂ − x₁)² equals (x₁ − x₂)², so you get the same answer either way.

How do I simplify the square root?

Pull out perfect squares: √20 = √(4 × 5) = 2√5.
