  {width?: string | number,height?: string | number,radiusWidth?: string | number,radiusHeight?: string | number})

**Parameters**

| Name| Type| Mandatory| Default Value| Description|
| -------- | -------- | -------- | -------- | -------- |
| width | string \| number | No| 0 | Width.|
| height | string \| number | No| 0 | Height.|

| radiusHeight | string \| number | No| 0 | Height of the rounded corner.|


## Attributes

In addition to the [universal attributes](ts-universal-attributes-size.md), the following attributes are supported.

| Name| Type| Default Value| Description|
| -------- | -------- | -------- | -------- |
| radiusWidth | string \| number | 0 | Width of the rounded corner. The width and height are the same when only the width is set.|
| radiusHeight | string \| number | 0 | Height of the rounded corner. The width and height are the same only when the height is set.|
| radius | string \| number \| Array&lt;string \| number&gt; | 0 | Radius of the rounded corner. You can set separate radiuses for four rounded corners.|
| fill | [ResourceColor](ts-types.md) | Color.Black | Color of the fill area.|
| fillOpacity | number \| string \| [Resource](ts-types.md#resource)| 1 | Opacity of the fill area.|
| stroke | [ResourceColor](ts-types.md) | - | Stroke color. If this attribute is not set, the component does not have any stroke.|
| strokeDashArray | Array&lt;Length&gt; | [] | Stroke dashes.|
| strokeDashOffset | number \| string | 0 | Offset of the start point for drawing the stroke.|
| strokeLineCap | [LineCapStyle](ts-appendix-enums.md#linecapstyle) | LineCapStyle.Butt | Cap style of the stroke.|
| strokeLineJoin | [LineJoinStyle](ts-appendix-enums.md#linejoinstyle) | LineJoinStyle.Miter | Join style of the stroke.|
| strokeMiterLimit | number \| string | 4 | Limit on the ratio of the miter length to the value of **strokeWidth** used to draw a miter join. The miter length indicates the distance from the outer tip to the inner corner of the miter.<br>**NOTE**<br>This attribute must be set to a value greater than or equal to 1 and takes effect when **strokeLineJoin** is set to **LineJoinStyle.Miter**.|
| strokeOpacity | number \| string \| [Resource](ts-types.md#resource)| 1 | Stroke opacity.<br>**NOTE**<br>The value range is [0.0, 1.0]. If the set value is less than 0.0, **0.0** will be used. If the set value is greater than 1.0, **1.0** will be used.|

| antiAlias | boolean | true | Whether anti-aliasing is enabled.|


## Example

```ts
// xxx.ets
@Entry
@Component
struct RectExample {
  build() {
    Column({ space: 10 }) {
      Text('normal').fontSize(11).fontColor(0xCCCCCC).width('90%')
      // Draw a 90% x 50 rectangle.
      Column({ space: 5 }) {
        Text('normal').fontSize(9).fontColor(0xCCCCCC).width('90%')
        // Draw a 90% x 50 rectangle.
        Rect({ width: '90%', height: 50 })
          .fill(Color.Pink)
          .stroke(Color.Transparent)
        // Draw a 90% x 50 rectangle.
        Rect()
          .width('90%')
          .height(50)
          .fillOpacity(0)
          .stroke(Color.Red)
          .strokeWidth(3)

        Text('with rounded corners').fontSize(11).fontColor(0xCCCCCC).width('90%')
        // Draw a 90% x 80 rectangle, with the width and height of its rounded corners being 40 and 20, respectively.
        Rect({ width: '90%', height: 80 })
          .radiusHeight(20)
          .radiusWidth(40)
          .fill(Color.Pink)
          .stroke(Color.Transparent)
        // Draw a 90% x 80 rectangle, with the width and height of its rounded corners being both 20.
        Rect({ width: '90%', height: 80 })
          .radius(20)
          .fill(Color.Pink)
          .stroke(Color.Transparent)
      }.width('100%').margin({ top: 10 })
      // Draw a 90% x 50 rectangle, with the width and height of its rounded corners as follows: 40 for the upper left rounded corner, 20 for the upper right rounded corner, 40 for the lower right rounded corner, and 20 for the lower left rounded corner.
      Rect({ width: '90%', height: 80 })
        .radius([[40, 40], [20, 20], [40, 40], [20, 20]])
        .fill(Color.Pink)
        .stroke(Color.Transparent)
