# setWidth(_:forSegment:)

Sets the width of the specified segment.

## Declaration

```swift
func setWidth(_ width: CGFloat, forSegment segment: Int)
```

## Parameters

- `width`: The width of the segment, measured in points. Specify the value 0 if you want the segment to be sized to fit the available space automatically.
- `segment`: The index of the segment whose width you want to set. This method raises an exception (doc://com.apple.documentation/documentation/Foundation/NSExceptionName/rangeException) if the index is out of bounds.
