At present, there is no standard size for this. I am a red silk dance instructor. I write and perform my own dances. As a beginner, you can jump from four meters, and then gradually stretch to more than six meters, eight meters, ten meters and twelve meters. I perform 12 meters on stage and dance 20 meters at ordinary times. The advantage of silk dancing is that you can keep fit. Fat people can lose weight and get rid of excess fat during silk dancing. Thin people can increase their physique in silk dancing activities. Generally, dancing colored silk is 25 cm, 35 cm and 50 cm wide. This is my personal hobby, I hope friends with this hobby can communicate more!
