config.lua question and text size

If I build my settings according to say an iphone6 (However, I realize it’s better to build to a smaller device and scale upwards ) and for a textField I choose the visually optimal textField.size = 12…does that mean on an iPhone 6plus that the textField.size STILL is a visually optimal size? For example, it will be adjusted to 15 BUT the ratio of textField.size to total textField dimensions should be relatively equal for the iphone6 vs iphone6 plus?

Are you doing adaptive or letterbox scaling in your config.lua?
