title: "Shapes"
description: "Material surfaces can be displayed in different shapes. Shapes direct attention, identify
components, communicate state, and express brand.

The shape scale defines the style of container corners, offering a range of roundedness from
square to fully circular.

There are different sizes of shapes:
- Extra Small
- Small
- Medium
- Large
- Extra Large

You can customize the shape system for all components in the [MaterialTheme] or you can do it on
a per component basis.

You can change the shape that a component has by overriding the shape parameter for that
component. For example, by default, buttons use the shape style “full.” If your product requires
a smaller amount of roundedness, you can override the shape parameter with a different shape
value like MaterialTheme.shapes.small.

To learn more about shapes, see
[Material Design shapes](https://m3.material.io/styles/shape/overview)."
