Height is standart DVD, so it's 5 mm too tall.
That really doesn't matter that much, either stretch the height 5mm, or leave 5mm white stripe to the bottom (like I do) or leave to cover just as it is (the difference is 2.5mm on top and bottom, and it's not that noticeable).
The cases I use have 27.5mm spine, but actually the 26mm spine might be better.

Oh and just noticed you PM, hope it doesn't matter that I answer publicly:
Cases are bit larger that UGCs, so the big NES, SNES and N64 (and Jaguar) manuals fit perfectly, UGC have trouble with them.
Why I use DVD cases instead of VHS cases, there are 2 reasons:
1: VHS cases too had trouble fitting the manuals (+ some DVD cases have holders for the manuals).
2: The match the other DVD game cases
3: DVD cases were easier to come by.
4: DVD cases were cheaper.
Later I figured one more:
5: DVD cases are found up to 36mm (or was even 48mm) thick, so if you're having trouble with fitting game + thick manual or specific game (NEO GEO games ?) , you can always buy thicker case.
And yes they fit NES, SNES and N64 games, as well as Super Gameboy, Jaguar games.
The thicker ones can fit Pro Action Replays and such also.
And sure I can take photo of the inside, but it's just like any DVD case, but thicker and has the disc holder also inside the front cover.
Currently I'm not using anything to hold the games in place.
