While it’s not a perfect fit for everyone depending on leg, torso and arm length, there is a general rule for how to size a jump rope for people learning to do dubs. You stand with both feet in the middle of your rope and then hold the two handles up. The top of the handles should come to your armpits. Once you have the correct sizing, do single jumps and have someone watch you. When the rope hits the ground during the jumps, have your spotter make sure that the rope isn’t bouncing up off the ground at you. The rope should graze the ground, not visibly bounce up at you. When the rope starts bouncing it is too long, it may trip you up and becomes quite difficult to turn with just your wrists (making dubs harder than they have to be).
As you become more proficient at your dubs, you may want to shorten your rope to make them more efficient. I prefer my jump rope to be a few inches below my armpits on both sides because I find that any bouncing really bothers me and slows my dubs down. Also, the shorter rope forces me to be more efficient when I get tired because I’m forced to keep my arms in closer to my sides…but technique is topic for another day.
Disclaimer: this rule of thumb only really applies to dubs and basic tricks with the rope. If you’re interested in getting into speed rope or other complex tricks, the rope will need to be much shorter or longer or you may want a beaded rope. Below is a video of a jump rope team for your viewing enjoyment (if you are short on time, skip toward then end, it gets better and better). If you have children, I highly recommend introducing them to jump rope. If you can imagine how tired you get jumping rope for 3-4 min when you warm up, think about this 8 min long routine using heavy beaded ropes, or their multiple hour long practices. Needless to say it gets you in great shape and improves coordination.
