What is Distance Between Two Points?
The Distance Between Two Points calculation tells you your distance from a few simple inputs. The figure you are solving for here is the distance.
The Distance Between Two Points formula
The core formula is:
Distance = √((x₂ - x₁) ^ 2 + (y₂ - y₁) ^ 2)Here is what each input means:
- x₁ — a number. Example: 0.
- y₁ — a number. Example: 0.
- x₂ — a number. Example: 3.
- y₂ — a number. Example: 4.
How to calculate it step by step
- Write down the x₁ (for example, 0).
- Write down the y₁ (for example, 0).
- Write down the x₂ (for example, 3).
- Write down the y₂ (for example, 4).
- Apply the formula above to get your distance.
- Double-check the result with the Distance Between Two Points Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| x₁ | 0 |
| y₁ | 0 |
| x₂ | 3 |
| y₂ | 4 |
| Distance | 5.0000 |
With x₁ of 0, y₁ of 0, x₂ of 3 and y₂ of 4, the distance works out to 5.0000.
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
