Elaborate please. Here is a link with the dimensions of the otterbox defender. It is 1.6 inches thick. So yes my 1 inch was being nice to them.

Those dimensions are wrong and so are you with your 1 inch rambling. Mystery solved.
Even the otterbox defender for iPhone 5, which is a thicker device, is less than 3/4" thick.
