# maxItemSize

The maximum size (in points) of items in the collection view grid.

## Declaration

```swift
var maxItemSize: NSSize { get set }
```

## Discussion

Discussion Setting the size to (0, 0) means that there is no maximum grid size. The default value of this property is (0, 0). If an item’s view  is resizable, set the value to the maximum size that the view should use.
