# `GSFont.canonicalAxes`

*Instance Property*

## Declaration

```swift
var canonicalAxes: [GSAxis] { get }

```

```python
canonicalAxes() -> list[GSAxis]
```

## Discussion

This is a filtered view of [`GSFont.axes`](/Core/GlyphsCore/GSFont/axes) containing only axes for standard OpenType design axes. See [`GSAxis.isCanonical`](/Core/GlyphsCore/GSAxis/isCanonical) for details.
