# width

The size of the list.

## Declaration

```swift
var width: ListFormatStyle<Style, Base>.Width
```

## Discussion

Discussion The width property controls the size of the list. The locale determines the formatting and abbreviation of the string for the given width. For example, for English: ["One", "Two", "Three"].formatted(.list(type: .and, width: .standard)) // “One, Two, and Three”

["One", "Two", "Three"].formatted(.list(type: .and, width: .short)) // “One, Two, & Three”

["One", "Two", "Three"].formatted(.list(type: .and, width: .narrow)) // “One, Two, Three”  The default value is ListFormatStyle.Width.standard.
