How to Size your Rope

We follow two basic principles with regard to jump rope length; The first is “static” rope length. That’s the actual length of a rope not in motion. The second is “dynamic” rope length. That’s the rope in motion where the athlete’s mechanics can influence the effective length of the rope.

Our sizing chart will attempt to guide you to an ideal “static” rope length. This rope length is intended to fit a specific posture while jumping. That posture can be described as follows. Starting with your anchor point, which is your hand placement. Hands should be positioned at your midline axis and right at your frontal plain. Your hands can slide in or out along this axis depending on your shoulder’s external rotational flexibility.

Your elbows should be relaxed down by your side with your shoulders as disengaged as possible. Again external rotational flexibility may dictate whether your elbows need to pull backwards in order to keep your hands from shifting forward of your frontal plain. Once we have your anchor point isolated at your midline axis we then look for your jump rope to have an even turnover passing over head and in front of the toes with a minimum of 12" clearance at both points.

If we’ve met all of those standards then we’ve placed the athlete in the best possible position to have balance and symmetry between their body and their rope. It will now only depend on the athlete’s efficiency of mechanics to dictate their “dynamic” rope length

When viewing the sizing chart (see Images & Videos tab) please locate your height while wearing your normal work out shoes. Then see the indicated rope length recommended for that height. That is the measurement you would select when purchasing your Custom Rx Jump Rope.

Recommend - RX Custom Jump Cable

Five Cable Choices To Cover All Work Capacities:

Hyper 1.3 ounces - Aircraft grade cable with PVC coating. Our lightest offering weighing only 1.3 ounces for a 9' length (excluding handles). Most comparable to traditional speed cables. The PVC coating does not retain memory and therefore uncoils nicely. This cable produces the fastest cycle rate therefor the athlete must be extremely proficient at double unders. Recommended for advanced jumpers who can already turn 75+ double unders.

Ultra 1.8 ounces - Aircraft grade cable with PVC coating. Our second lightest cable weighing 1.8 ounces for a 9' length (excluding handles). The Ultra 1.8 is considered our “hybrid speed cable” due to its light nature while offering more feedback to the athlete. The increased resistance allows the athlete to turn the Ultra 1.8 cable at a slightly slower cycle rate than the Hyper 1.3 yet triple unders are still plentiful. Recommended for advanced jumpers who can already turn 60+ double unders.

Elite 2.6 ounces - Aircraft grade cable with PVC coating. Our mid range weighted cable weighing 2.6 ounces for a 9' length (excluding handles). Our most all around utility cable offering a nice blend of light weight with increased feedback and response while it’s rigidity maintains a nice “horse shoe” shape while in motion. Recommended for jumpers who can already turn 50+ double unders.

Buff 3.4 ounces - Aircraft grade cable with PVC coating. Our third heaviest cable weighing 3.4 ounces per 9' length (excluding handles). Our Dual Threat cable which provides tremendous feedback allowing the athlete to jump with a broader range of tempos from very slow to super fast. Ideal for beginners to gain a better feel for timing while jumping at slower tempos. Also a fantastic training cable for advanced jumpers looking for greater resistance and intensity in their training.

Beast 4.1 ounces - Aircraft grade cable with PVC coating. Currently our heaviest cable weighing 4.1 ounces per 9' length (excluding handles). Our bruiser cable that provides the pain that masochist seek in their high intensity training. Also great for bigger, stronger athletes needing more resistance and feedback than most typical jump ropes provide.

Rated 5 out of 5 by from Great for learning double unders After struggling a bit with a lighter weight jump rope, I found some online reviews stating RX Smart Gear’s weighted ropes were a great way to get feedback. I have found this to be true and enjoy the challenge of a heavier rope during workouts. I have noticed I get more consistent double unders although I am still working on stringing several together. When going back to a lighter rope, I can tell I have majorly improved my timing and consistency. I would defiantly recommend this rope to anyone just starting out or looking for a challenge to build endurance during workouts. The build quality is great and I wish I would would have invest in one much sooner!

Rated 5 out of 5 by from Perfect rope for me - 2.6 oz. I thought my problem with DUs was speed, so I thought I needed a faster rope. I could barely get 20 DU unbroken, and if the WOD called for more than 3 rounds I was usually doing sets of 5 DU by the last round. Two weeks ago I couldn't find the rope I usually use at my box, so I grabbed an Rx Jump rope even though it was a little too short. The WOD was 5 rounds and included 25 DU in each round. I got all 25 DU unbroken in every round, and I was incredibly more efficient (less tired). I was amazed, using this rope was likely flipping a switch on my DUs. I bought my own rope (2.6 oz) at the correct length and did "Annie" last night as soon as it was delivered. Took 3 minutes off my previous time and came very close to getting 50 DU unbroken. If you are an intermediate DUer, give this rope serious consideration. I don't think I would have bought it if I hadn't used it at my box first, but luckily I did.

Rated 4 out of 5 by from 70 DU's Later... I originally bought one of the heavier (2.3oz, I think) RX ropes and it was very helpful to learn the timing and the swing of Double Unders, although the whips hurt like heck! I then bought the 1.8oz and after 7 weeks, I have worn through the casing from practicing 3-5x a week, 15 - 30 minutes a session. 7 Weeks into my practice, I am hitting 50's more often, almost daily and my high is a surprising 70! I do wish they lasted longer, but I am using it pretty heavily, hence the 4-star review. But once you figure them out, I'm sticking with what is working and that's why I'm re-ordering 2 more cables for the 1.8oz rope.

Rated 5 out of 5 by from Perfect Rope Having this rope has made a huge difference in my double unders. Max before was 12 or 13, and first WOD with the new rope I banged out 30 in a row. I am so Pumped!!!

Rated 5 out of 5 by from Best Jump Rope The Rx Jump Rope was a game changer for me. I'm an ex-athlete who is new to crossfit and really struggled getting double unders down til I got one of these. It didn't happen the first day I bought it. However, with a little bit of practice I was able to use the weighted version of the Rx Rope to help slow down my DU cycles to match what I was doing with singles and ultimately find a rhythm. Thanks Rx Jump Ropes/Rogue! -Dan

Rated 4 out of 5 by from While not indestructible, still a great rope I bought this rope because of COVID-19, to work on my double unders while I'm at home and away from the gym. This rope is the one I use at my gym, and I have been really pleased with how its weight and feedback has made it possible for me to learn DUs. (Using it, I am up to 50 in a row; I wasn't able to do a single one when I started.) So I have zero complaints about the performance of the rope itself. That said, if you use it outside on pavement, it doesn't hold up well. I wouldn't call it a durable rope when compared to other ropes that I have used, but if you don't mind replacing an expensive rope every few months, it's a great option for a beginner like me. My other ropes, like my Loma rope, are more durable but are lighter and harder for a beginner to use because they provide less feedback. I guess it's a trade-off.

Rated 5 out of 5 by from Nice rope makes a great travel buddy I love having my own rope even when I am at my home CrossFit box because I always know I'll have exactly the length and weight I want. I have been traveling a lot this summer and having my own rope helps me do modified WODs on the go--just a great and small home gym item. I got the 3.4 oz rope as recommended for those who haven't mastered double unders yet and it was an adjustment, at first from the lighter ropes at my box, but I really think it's helping me improve so I can master the DU sooner. I am so happy with this purchase! I may buy a lighter version as I improve, also.

Rated 5 out of 5 by from Perfect for beginners and bigger guys Never left an online review of a product in my life. Been using a speed rope and stuck doing single/double combos for a year. Just couldn’t string them together. Got the 4.1 oz heavier rope hoping that would help and it definitely did. Strung double unders together the first time out of the box. Not everyone will have the same results but if you’re a beginner and a bigger guy (I’m 6-2 215#) give it a shot, I can feel the rope a lot more than the lighter ones. Wish I tried this sooner. Rope was perfect length too.
