# InternalBufferCapacityAttribute

> Specifies the maximum number of elements to store inside a chunk.

## Definition

* **Type:** Class
* **Namespace:** [Unity.Entities](/engine/7000.0/script-reference/unity/entities.md)
* **Assembly:** UnityEngine.EntitiesModule
* **Inherits from:** [Attribute](https://learn.microsoft.com/dotnet/api/system.attribute)

```csharp
[AttributeUsage(AttributeTargets.Struct)]
public class InternalBufferCapacityAttribute : Attribute
```

## Remarks

Use this attribute on the declaration of your IBufferElementData subtype:

\[InternalBufferCapacity(10)] public struct FloatBufferElement : IBufferElementData \{ public float Value; }

All [DynamicBuffer\<T>](/engine/7000.0/script-reference/unity/entities/dynamicbuffer1.md) with this type of element store the specified number of elements inside the chunk along with other component types in the same archetype. When the number of elements in the buffer exceeds this limit, the entire buffer is moved outside the chunk.

[DefaultBufferCapacityNumerator](/engine/7000.0/script-reference/unity/entities/typemanager/defaultbuffercapacitynumerator.md) defines the default number of elements.
