## API Reference

> Source set: Common

```kotlin
public sealed class Breadth : Interpolatable
```

Specifies dimension breadths for styling.

A [Breadth](/jetpack-compose/androidx.compose.foundation/foundation/functions/Breadth/api) is a value that can either be a fraction of the parent or a specific `Dp` value. For
example, properties for "width" and "height" are good candidates for [Breadth](/jetpack-compose/androidx.compose.foundation/foundation/functions/Breadth/api).
