# sizeOfLabel(_:)

Calculates the size of the receiver’s label.

```
func sizeOfLabel(_ computeMin: Bool) -> NSSize
```

## Discussion

If `shouldTruncateLabel` is <doc://com.apple.documentation/documentation/Swift/false>, returns the size of the receiver’s full label. If `shouldTruncateLabel` is <doc://com.apple.documentation/documentation/Swift/true>, returns the truncated size. If your application does anything to change the size of tab labels, such as overriding the [`drawLabel(_:in:)`](/documentation/AppKit/NSTabViewItem/drawLabel(_:in:)) method to add an icon to each tab, you should override [`sizeOfLabel(_:)`](/documentation/AppKit/NSTabViewItem/sizeOfLabel(_:)) too so the NSTabView knows the correct size for the tab label.
