How to make text use all available space ("best fit")

Unity Engine

Old component based UI had an option for Text called “best fit”. This would choose a font size from a given range (min/max) such that the available space is filled as much as possible without cutting off anything.

How can I achieve a “best fit” font size with UIToolkit?

I tried size: 100% but this seems to be relative to something unrelated to the current VisualElement size as well as the parent VisualElement size (in Unity 2021.2.0.f1).
For example, it does not change when I resize the parent.

Hi @achimmihca !

Unfortunately, the “Auto-Size” property available in TextMeshPro is not yet available in UI Toolkit. It’s on our Roadmap, but it’s unlikely this will be tackled in 2022.2.

As for font-size, the parser allows to enter “percent” values, but it’s actually not supported. Sorry for the confusion, I’ll take a note to make sure this will be revisited.

Can you tell me more about what’s your use case ? If “auto size” is really needed you could likely implement your own version using the MeasureTextSize API.

myLabel.MeasureTextSize();
