> The size of each particle.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine.ParticleSystemJobs](/engine/6000.6/script-reference/unityengine/particlesystemjobs.md)
* **Assembly:** UnityEngine.ParticleSystemModule

public readonly ParticleSystemNativeArray3 sizes { get; }

### Remarks

When using 3D sizes, all three axes contain data, otherwise only the x-axis contains size data, and Unity applies it uniformly to each axis.
