Step 1: Size your cable OR take the Quiz above

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 plane. 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 plane. 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 30cm/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 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.

Should you have any questions on optimal cable weight and length please get in contact here. We answer sizing questions regularly and are happy to help.

Step 2: Choose your Coated Cable weight (Original Rx Jump Rope & EVO Speed Rope)


Our lightest offering weighing only 37 grams (1.3 ounces) for a 9 foot (2.74m) length (excluding handles). Most comparable to traditional speed cables. 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.


Our second lightest cable weighing 51 grams (1.8 ounces) for a 9 foot (2.74m) 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.


Our mid range weighted cable weighing 74 grams (2.6 ounces) per 9 foot (2.74m) 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.


Our second to heaviest cable weighing 96 grams (3.4 ounces) per 9 foot (2.74m) 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.

Or Step 2: Choose your Uncoated Cable weight (EVO Speed Rope only)

In addition to Hyper, Ultra, Elite and Buff cables, the EVO Speed Rope is available in uncoated speed cables:


Aircraft grade cable without coating which is our lightest cable offering.  Most comparable to traditional speed cables (comparable to Hyper). The uncoated wire provides a reduction in drag and cuts through the air with more ease. Recommended for advanced jumpers who can already turn 75+ double unders or are working on triple unders.


Aircraft grade cable without coating. The Heavy Metal cable offering weighs just mere grams more than the Speed Metal cable (comparable to Elite).  Heavy Metal is our secret weapon for triple unders and quadruple unders due to its perfect balance of weight and rigidity that provides essential feedback to the athlete. Recommended for advanced jumpers who can already turn 60+ double unders or are working on triple unders.
