# standardDimension

The system standard layout dimension for reserved layout size.

## Declaration

```swift
static let standardDimension: CGFloat
```

## Discussion

Discussion Setting the reservedLayoutSize width or height to this constant results in using the system standard value for a symbol image for that dimension, even when the image is not a symbol image.
