Don't you mean that "none of the FF characters official height makes any sense"?

Sephiroth should be 5'10" not 6'1",
No, he should be 6'1'', but in a lot of the other installments, he appears much taller. If he was just 5'10'', then Cloud would have to be A LOT shorter than he is now, because Seph is always shown as being a great deal taller than he is:
Picture Comparison:

Of course, that's with the Advent Children models. I don't know if the producers went with appropriate height scales when they made the movie. They changed a few of the characters' designs around to fit in with the more realistic look that the movie portrayed.
