# Distance calculations

PHPCoord can calculate the distance between two `Point`

s via the `calculateDistance()`

method.

```
public function calculateDistance(
Point $to,
): Length
```

The distance between two

`ProjectedPoint`

s is calculated via PythagorasThe distance between two

`GeographicPoint`

s or two`GeocentricPoint`

s is calculated via Vincenty’s formulaThe distance between two

`VerticalPoint`

s is calculated as simple difference

Example

```
$from = GeographicPoint::create(...);
$to = GeographicPoint::create(...);
$distance = $from->calculateDistance($to);
```
