# width The width of the measurement unit. ``` var width: Measurement.FormatStyle.UnitWidth ``` ## Discussion The `width` property specifies the display of the measurement unit. The possible values are [`abbreviated`](/documentation/Foundation/Measurement/FormatStyle/UnitWidth/abbreviated), [`narrow`](/documentation/Foundation/Measurement/FormatStyle/UnitWidth/narrow), and [`wide`](/documentation/Foundation/Measurement/FormatStyle/UnitWidth/wide). The format style represents the unit in the shortest notation available. The following example shows *100 degrees Fahrenheit* in each width for the `en_US` locale. ```swift let temperatureMeasurement = Measurement(value: 100, unit: .fahrenheit) temperatureMeasurement.formatted(.measurement(width: .wide)) // 100 degrees Fahrenheit temperatureMeasurement.formatted(.measurement(width: .abbreviated)) // 100°F temperatureMeasurement.formatted(.measurement(width: .narrow)) // 100° ``` --- Copyright © 2026 Apple Inc.
