# particleSize

The starting size of each particle.

## Declaration

```swift
var particleSize: CGSize { get set }
```

## Discussion

Discussion The default value is CGSizeZero. If set to the default, the size of the texture stored in the particleTexture property is used to determine the size of a particle. If a texture has not been assigned, you must set this property to a non-empty size.
