# widthForSegment(at:)

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

```
func widthForSegment(at segment: Int) -> CGFloat
```

## Parameters

`segment`

An index number identifying a segment in the control. It must be a number between 0 and the number of segments ([`numberOfSegments`](/documentation/UIKit/UISegmentedControl/numberOfSegments)) minus 1; the segmented control pins values exceeding this upper range to the last segment.

## Return Value

A float value specifying the width of the segment. If the value is {0.0}, [`UISegmentedControl`](/documentation/UIKit/UISegmentedControl) automatically sizes the segment.
