It's not a huge difference, but enough to make a difference for most cases: 7.5 mm vs 6.1mm**** it is? Thanks for letting me know, that makes me glad now I ended up picking the Pro because I assumed this would fit. I may just go for the replacement through Apple then, I definitely want to hang onto another iPad for media consumption and as much as I like my new Pro I’m not ready to let go of the classic iPad size, haha.
It’s the leather Smart Case which probably is broken in a bit but probably not enough to accommodate a thicker device.
