# hyphenationFactor

The threshold controlling when hyphenation is done.

## Declaration

```swift
var hyphenationFactor: Float { get set }
```

## Discussion

Discussion Whenever (width of the real contents of the line) / (the line fragment width) is below factor, hyphenation is attempted when laying out the line. Hyphenation slows down text layout and increases memory usage, so it should be used sparingly.
