Sorry I don't have the exact specs but I just put one on my iP5 last night and had the same concerns. There appears to be about 0.5 mm of glass exposed on each edge when perfectly applied which is consistent with their past products. No bunching with any of my cases and no exposed glass when in my generic TPU case.

I noticed the lines when I put it on yesterday but they rubbed off easily and left no residue.
