# Interface: BorderRadiusOptionsObject

## Highcharts. BorderRadiusOptionsObject

Detailed options for border radius.

### Members

#### radius :string|number

  The border radius. A number signifies pixels. A percentage string, like for example `50%`, signifies a relative size. For columns this is relative to the column width, for pies it is relative to the radius and the inner radius.

  ##### Type:

  - string | number

#### scope :string

  The scope of the rounding for column charts. In a stacked column chart, the value `point` means each single point will get rounded corners. The value `stack` means the rounding will apply to the full stack, so that only points close to the top or bottom will receive rounding.

  ##### Type:

  - string

#### where :string

  For column charts, where in the point or stack to apply rounding. The `end` value means only those corners at the point value will be rounded, leaving the corners at the base or threshold unrounded. This is the most intuitive behaviour. The `all` value means also the base will be rounded.

  ##### Type:

  - string
  Default Value:
    - end
