I know this is an old thread, but i thought I’d share my experience with respect to height differences:
In my small home town small tango community, if I didn’t constantly dance with leaders much shorter than me. I wouldn’t be dancing at all. My main maestro is considerably shorter than me and he constantly helped me with this issue during private lessons. When I started to spread my wings and dance elsewhere, like in NYC and at marathons/festivals, I was surprised that there were so many tall partners and how different it felt. Nice comfortable change. A luxurious treat. But then I started dancing internationally, mostly Northern Europe and Germany and my experience changed yet again. In Germany, where I now dance a lot, I at first encountered what seemed like segregation between short people and tall people! I was so used to try and get dances with anybody, any height, as long as I liked their dancing, that I couldn’t understand why the short guys often were so difficult to cabeceo. But I didn’t yet have the technique to dance with the really tall guys. Tall, as in, at my 178cm/ roughly 5’11”, plus moderate heels, I’m looking up to the top of their shoulder. I’ve learned to adapt and enjoy, but I have to say, there’s something so cool and gratifying about giving and getting a really good dance with a leader who is a head shorter than myself. I’ve noticed that when I am dancing with a very short guy, that a lot of people are watching us. At first I though they were thinking ‘oh that looks silly’, (and maybe they are, but I don’t care, and nobody thinks it looks strange when I’m dancing with a female leader who’s much shorter), but I actually think (or prefer to think) they are thinking ‘wow, they must both have some really good technique to be able to dance so well with each other’. Actually, it’s the musicality and style and connection that draws me to my favorite really short partners. My observation is that the short guys often have a more compact and fun style with great floor craft with lots of turns so they can see behind the follower.
Sometimes the local DJs announce the next tanda is ladies choice, and I often then go out of my way to find new-to-me short guys who might be intimidated. Some of them became regulars this way, often dancing 2+ tandas per milonga. Later I’ve noticed some of them being brave to dance with the ladies even taller than me. At my favorite weekly milonga there, I often count how many girls are taller than me, and I’m frequently the 5th tallest. One of the really tall guys who frequently drives from a city 2 hours away outright says he comes specifically to dance with all the friendly tall girls and that we gave a reputation.
Oh, also, my first experience dancing in Berlin was interesting with respect to height. I had for a very long time wanted to make my pilgrimage to the tango scene there like others go to BsAs, because I heard so many positive things about the scene and the very high level of the dancers. Not knowing a single person, I walk into a big crowded event, thinking I’ll just be ‘ironing the chairs’ most of the evening and just observe the scene. I get invited within seconds by a very good tall dancer who picked me out for my height, not having a clue whether I could dance or not. And again and again and again for what seemed like every single tanda all evening and the next couple of days, all tall guys. Often they had not seen me dance before they invited me. I hardly had to do anything myself to get a cabeceo. Wow. Not complaining one bit, but what a relief when I finally got to dance with someone slightly shorter than myself.
