# kCTFontOrientationAttribute

The orientation for the glyphs of the font.

```
let kCTFontOrientationAttribute: CFString
```

## Discussion

The value associated with this key is an integer represented as a <doc://com.apple.documentation/documentation/CoreFoundation/CFNumber> object containing one of the constants in [`CTFontOrientation`](/documentation/CoreText/CTFontOrientation). If you want to receive vertical metrics from a font for vertical rendering, specify [`kCTFontVerticalOrientation`](/documentation/CoreText/CTFontOrientation/kCTFontVerticalOrientation). If unspecified, the font uses its native orientation.
