# fullScreenAccessoryViewMaxHeight

The maximum height of the toolbar’s full screen accessory view, in points.

```
var fullScreenAccessoryViewMaxHeight: CGFloat { get set }
```

## Discussion

The [`fullScreenAccessoryViewMaxHeight`](/documentation/AppKit/NSToolbar/fullScreenAccessoryViewMaxHeight) is used when displaying a fully revealed menu bar. During the reveal, the toolbar’s accessory view’s frame is interpolated between its [`fullScreenAccessoryViewMinHeight`](/documentation/AppKit/NSToolbar/fullScreenAccessoryViewMinHeight) and `fullScreenAccessoryViewMaxHeight` properties.

By default the maximum height gets set to the height of the accessory view’s frame when it’s set.
