I've never gotten to date a girl taller than me, though I've wanted to several times when I saw a very pretty tall one.
I think probably I would settle on a slim girl who is close to my height (5'7) or slightly shorter (not too much shorter), as is the case with my wife.
There's a hug/dance test there for me. It's comfortable for me if a girl's figure feels nice to hold, is easy to hold tight (no giant breasts, e. g.), and we can dance cheek to cheek, so to speak, without either of us having to bend down.

A taller girl. I like being the shorter one which isn't hard at 5'2.
