I'm creating a desktop solution which has iPad and iPhone 6 components. For the desktop I'm using Enlighten theme. For the iPad I'm using Enlightened Touch. This touch theme has a field height of 44pt, which looks fine for the iPad but it seems like it would be too tall for the iPhone 6 (portrait view).
I have a smart phone (Android) but I must admit I don't do much with it beyond phone, text, and checking email.
What is the optimal height for iPhone 6 portrait view? I did check iOS design guides but couldn't find a point size for font fields.
