# setWidth(_:forSegmentAt:)

Sets the width of the segment at the index you specify.

## Declaration

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

## Parameters

- `width`: A float value specifying the width of the segment. The default value is {0.0}, which tells UISegmentedControl to automatically size the segment.
- `segment`: An index number identifying a segment in the control. It must be a number between 0 and the number of segments (doc://com.apple.uikit/documentation/UIKit/UISegmentedControl/numberOfSegments) minus 1; the segmented control pins values exceeding this upper range to the last segment.
