# dynamicTypeSize

The current Dynamic Type size.

```
var dynamicTypeSize: DynamicTypeSize { get set }
```

## Discussion

This value changes as the user’s chosen Dynamic Type size changes. The
default value is device-dependent.

When limiting the Dynamic Type size, consider if adding a
large content view with [`accessibilityShowsLargeContentViewer()`](/documentation/SwiftUI/View/accessibilityShowsLargeContentViewer())
would be appropriate.

On macOS, this value cannot be changed by users and does not affect the
text size.
