I'm 5'2....
If I have to stand on something to kiss you, you're too tall.
I (generally, but not always) prefer shorter guys. Maybe not as short as I am, but short enough that neither of us are damaging vertebrae to make out.
However, I've found that plenty of taller, often more masculine guys tend to prefer me potentially due to my height.
In short, everything is relative... everything is subjective.
