The SE was the one that shared the 8's dimensions, the Mini was smaller than both. That Mini appears to be in a case, so the comparison photos aren't as useful as they'd be otherwise.
(Also, it looks like I couldn't do arithmetic earlier or typo'd the number, the Mini is 0.12" narrower, not 0.13").
Maybe because it's the dark version of the phone you can barely make out the shiny apple logo, but it's there, you can see the metal edge of the phone.
It's not in a case.. obviously, that would be a stupid comparison.
"SE" is a nondescript product line and the only physical differences are the tone of the chassis and a stamp; it's a fair representation of the size of a 5.
