# weight

The face region’s weight.

## Declaration

```swift
var weight: Double { get }
```

## Discussion

Discussion The weight of a region of interest represents the pervasiveness of the face across the project as a whole. All regions of interest with the same identifier share the same weight. The values range between 0 and 1. The default value is 0.5.

For projects focused on animation or transition between assets, focus on the regions with the highest weight to ensure that your presentation features areas of greatest interest to the user.
