They say that the ideal height is for the man to be about 4 inches taller than the woman.
But I'm also 5'8" in bare feet and I wouldn't dance much if I waited only for partners that tall! I often dance with men shorter than I am in heels.
Whether a height difference matters depends on your goals. For social dancing, it makes next to no difference. For competitive dancing, hieght difference matters less in latin than in ballroom. At the lower levels of ballroom competition, I'd say it might be a slight disadvantage in your overall look, but if you develop a nice topline and dance well into your knees, it shouldn't be too visible. If your ambition is to make it to the top in competitive dancing, a taller partner would probably be better for you.
