Why do you need it? With Corona SDK you define a content grid of your point and Corona handles the scaling for you.

But if you look at the system.getInfo() API docs, there are ways to get various bits of info including the width and height. Once you have that it’s a simple Pythagorean theorem to calculate the diagonal:

local diagonal = math.sqrt( width * width + height * height )
