The 8 had a 4.7" screen and 6" (diagonal) footprint.
The 5 had a 4" screen and 5.4" footprint.
An "all-screen" phone with a 5.4" display would be have the footprint of an iPhone 5, like I said. (and that's an 8 Plus — not just an 8 — sized screen)
((still too big, imho, I want something in the iPhone 4 footprint, but I'll take what I can get))
