This section covers both rope cable length as well as cable weight principles from our partners RX Smartgear. Although the section on cable length and sizing is from RX Smartgear, it is relevant for all jump ropes.
Sizing your jump rope is important in order to make sure that learning and progression is effective as possible. We find that many people tend to use ropes that are too long for them which can hinder learning and proper jump rope form. Appropriate length can also vary depending on your workout objectives and goals.
We recommend following the RX Smartgear sizing principles. This is particularly important to review if you are purchasing an RX Smartgear jump rope as these are none adjustable and so you need to make sure you purchase the appropriate cable length (and weight!). These principles are also useful for sizing any jump rope and so good to understand even if you don't have an RX! See below information and video on RX sizing.
RX Method and Sizing guide
Sizing is ultimately down to personal preference which makes it tricky to have a sizing guide that is perfect for each individual. For example, arm length, workout objective and experience level can all impact the optimal rope length, not just your height.
If you are a beginner to intermediate skill level jumper (i.e. 0-50 double unders) it is important to begin with an approach that gives you a foundational starting point and then follows a progression for improvement just like any other high skilled movement. Choosing the correct jump rope size is actually a 2 part process: First, choose a length that correlates to your height. Second, adjust your positioning to fit that rope allowing adequate spacing overhead and underfoot.
The Rx Sizing Method is a progression based approach with the goal to ultimately place you in a rope length that produces efficient mechanics and positioning. The suggested length correlates to your height to provide an abundance of rope clearance overhead and underfoot yet not so much as to force poor positioning and inefficient movement patterns. The Beginner to Intermediate length recommendation (height plus 3ft) should be viewed as your starting point and all efforts should be directed towards moving to a shorter rope length over time. A shorter rope length requires more compact positioning, which reduces fatigue in the larger muscle groups as well as produces a faster cycle rate per rotation. In essence, a shorter rope will allow you to perform more work faster with less energy expended.
RX Sizing Recommendation:
Beginner to Intermediate (0-50 Double Unders) Height Plus 3 feet . Example: 6 foot height plus 3 feet = 9 foot rope length
If you are an experienced jumper measure your current rope or choose a length you know works for you.
The chart below provides specific length recommendations for Beginner to Intermediate jumpers. Please use the images below to assess your current positioning and make the necessary adjustments to your recommended rope length from the chart. The more compact stance (elbows in, hands in) should be your goal in terms of jump rope form which these height recommendations are based on.

Note - recommendations can sometimes change if RX make changes and updates to their product mechanics or due to user testing/feedback. However these will be marginal changes, if any, and are unlikely to alter your jump rope experience!
The below is only relevant when purchasing RX Smartgear Jump Ropes
The RX Smartgear method focuses on starting with a heavier weighted cable which allows you to develop timing and technique for your double unders. When turning heavier weights you have better feel and feedback from the cable and simultaneously builds stamina. Once you are turning consecutive DUs, you then work your way down to lighter cables. With the technique and timing learned from the heavier rope, you will then be able to turn an even greater number of DUs with the lighter cables. See more detailed RX Smartgear cable weight descriptions and recommendations below:
Hyper 1.3 – NOT RECOMMENDED FOR BEGINNERS
Aircraft grade cable with PVC coating. Our lightest offering weighing only 1.3 ounces for a 9 foot length (excluding handles). Most comparable to traditional speed cables. The PVC coating does not retain memory and therefore uncoils nicely. This cable can produce the fastest cycle rate therefore the athlete must be extremely proficient at double unders. Recommended for advanced jumpers who can already turn 75+ double unders.
Ultra 1.8 – NOT RECOMMENDED FOR BEGINNERS
Aircraft grade cable with PVC coating. Our second lightest cable weighing 1.8 ounces for a 9 foot 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 – IDEAL FOR INTERMEDIATE TO ADVANCED
Aircraft grade cable with PVC coating. Our mid range weighted cable weighing 2.6 ounces for a 9 foot 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 – IDEAL FOR BEGINNERS TURNING LESS THAN 50 D/Us. IDEAL FOR ADVANCED LOOKING TO INCREASE INTENSITY.
Aircraft grade cable with PVC coating. Our third heaviest cable weighing 3.4 ounces per 9 foot 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.
EVO - Speed Metal - (RECOMMENDED FOR ADVANCED ONLY)
Aircraft grade cable without coating. Our lightest cable offering. Most comparable to traditional speed cables. 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.
EVO - Heavy Metal - (RECOMMENDED FOR ADVANCED ONLY)
Aircraft grade cable without coating. The Heavy Metal cable offering weighs just mere ounces more than the Speed Metal cable. 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.
