Aspect Ratio

AspectRatio is a property introduced by Yoga and is not present as a settable property in the css flexbox specification. Flexbox does have the notion of aspect ratio though for things with intrinsic aspect ratio such as images.

The aspect ratio property in Yoga has the following properties:

  • Accepts any floating point value > 0, the default is undefined.
  • Defined as the ratio between the width and the height of a node e.g. if a node has an aspect ratio of 2 then its width is twice the size of its height.
  • Respects the min and max dimensions of an item.
  • Has higher priority than flex grow
  • If aspect ratio, width, and height are set then the cross axis dimension is overridden.
