# vertexCount

The number of elements in the [`vertices`](/documentation/ARKit/ARFaceGeometry/vertices-fhdb) buffer.

```
@property (nonatomic, readonly) NSUInteger vertexCount;
```

## Discussion

Face mesh topology is constant across [`ARFaceGeometry`](/documentation/ARKit/ARFaceGeometry) instances, so the value of this property is the same for all instances.
