[Enhancement] More Accessible Font Sizes

More Accessible Font Sizes

There are a number of improvements to be made with regard to ensuring accessible font sizes. Being able to support a wide range of font sizes, especially with various accessibility settings for font scaling, is key.

This issue will be updated as exploration continues.

Named fonts

NamedSize and the corresponding platform-specific sizes should be reinvestigated.

Considerations, among others, should include:

• Minimum font size requirements for accessibility
• Consistency across platforms vs. with native platforms

Related issues:

• [Bug] Named font sizes don't correspond with the font sizes specified in the documentation xamarin/Xamarin.Forms#13628
• [Enhancement] Make named font size scaled for accessibility, and all numerical font sizes fixed xamarin/Xamarin.Forms#13543

Dynamic font sizes

Text should be rendered fully and appropriately, (without getting cut short anywhere), despite the font size, on all different...

• Platforms and devices
• Layouts and screen sizes
• Control sizes

This includes interaction with platform/device-specific accessibility settings for font scaling. For example, if the font is scaled to 200% on a device, all text in .NET MAUI apps should be scaled and rendered fully and appropriately.

Related issues:

• Label text getting cut off when using accessibility font scaling xamarin/Xamarin.Forms#13448
• Xamarin.Forms label not rendered correctly on iOS xamarin/Xamarin.Forms#11270

I am pleased these things are getting more attention :)

There are few extra features around this I would like support for (some of these are Forms-y and some Essentials-y but I guess they all go here now?):

• Text that isn't scaled, regardless of device setting.
• Scale an arbitrary size in the same way as font size.

(Of the two, I've used the second more often - think something like sizing the image of a custom radio button).

• Query the current accessible font scaling details.
• A notification when it changes.
