Documentation of Font Sizes on each watch model ???

I'm trying to support a wide range of Garmin Watches with my app.

Fitting fields on the display is one of the key challenges in supporting a wide range of devices.

I've discovered some real surprises in the meaning of FONT_TXINY, FONT_TINY, FONT_SMALL, etc across models.

Is there any documentation, any summary that shows the font sizes on each of the watches that Garmin has produced ???
