Not really ... short dancers are great. The dancers I know are generally not very good, boys 170- 180, girls 160- 170. The most important thing is to have a good figure proportion. Like some classical species, they need to have some special preferences, such as ballet, long neck and full forehead. Hip-hop, like breaking popin, is not to say that tall people can't dance well, but also very well, and most of them are short.
