# strokeWidth

The width of the stroke.

## Declaration

```swift
static let strokeWidth: NSAttributedString.Key
```

## Discussion

Discussion The value of this attribute is an NSNumber object containing a floating-point value. This value represents the amount to change the stroke width and is specified as a percentage of the font point size. Specify 0 (the default) for no additional changes. Specify positive values to change the stroke width alone. Specify negative values to stroke and fill the text. For example, a typical value for outlined text would be 3.0.
