Jump Rope Sizing: Get the Perfect Fit Before You Buy
WATCH NOW
Before purchasing your Rx Jump Rope or EVO Speed Rope, please review these 4 important sizing recommendations.
Rx and EVO ropes are custom-cut to the length you select. They are interchangeable but not adjustable, so choosing the correct size upfront is key to performance, efficiency, and confidence.
A little preparation goes a long way
OPTION 1: Measure Your Current Jump Rope (Most Accurate)
- Measure the cord only (do not include the handles).
- Round to the nearest even number.
- Round up for a little extra forgiveness.
- Round down for maximum efficiency and speed.
Example: 8'5” - Round to 8'6" for comfort or 8'4” for precision.
OPTION 2: Test Ropes at Your Gym (Highly Recommended)
- Try different rope lengths at your local gym.
- Choose the size that feels smooth, controlled, and efficient.
- Measure the rope and apply the same rounding rules as Option 1.
- Write your size down before ordering.
OPTION 3: Want Zero Guesswork? Choose RapidFit™
If you’re unsure about sizing or still refining your technique, we strongly recommend starting with our award-winning RapidFit™ Adjustable Jump Rope.
Why RapidFit?
- Instantly test multiple rope lengths.
- Progress at your own pace.
- Total peace of mind while dialing in your ideal size.
Once you know your perfect length, upgrading to Rx or EVO is easy.
OPTION 4: Use Height as a Starting Point (Best Educated Guess)
As a last option, you can estimate your rope size by:
Your Height + 3 feet = Suggested Rope Length
Important: This method is not guaranteed to be your best fit. Your form, mechanics, and timing are the biggest indicators of ideal rope length.
Use the Rope Size Calculator below to find the recommended size for your height.

If you jump with your Hands in, use our sizing chart or choose a length you know works for you.
If you jump with your Hands out, add a couple inches to our sizing chart or choose a length you know works for you.
If you jump with your Hands out, add a few inches to our chart, or choose a length you know works for you. If you jump this way, we recommend adding 3ft to your height.

HOW TO
Check your jump rope size
- Step on the rope with one foot, bring your feet together, and pull the rope tight.
- Bring the handles together and point the top towards your chest.
- Only check where the cable ends - do not include the handles with rope size.
- If you follow our length guidelines, the cable will stop at your sternum or lower pecs.
- The rope should not go higher than this point.
- Any longer than this will have too much rope over head, and will slap the ground excessively.
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 that follows a progression for improvement just like any other high skilled movement.
Choosing the correct jump rope size is actually a 2 part process:
- - Choose a length that correlates to your height.
- - Adjust your positioning to fit that rope with adequate spacing overhead and underfoot. You have to do work too! There are many components to proper arm positioning.
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 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 allows 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.

FAQ

Can the size be adjusted on all Rx Jump Rope products?
Only the RapidFit and the Frévo are adjustable Jump Ropes.All other Rx jump ropes come with fixed-length cables customized to your height and skill level. Please refer to our chart for sizing recommendations.
Is a speed rope the best to learn double unders with?
Speed wires are too light and too thin to develop good timing. A standard cable weight between 3-4 ounces is ideal for learning double unders. Our Buff 3.4 and Poseidon 4.1 fall in this range.
I am a beginner. Which jump rope should I choose?
The adjustable RapidFit and/or Original Rx Jump Rope with Buff 3.4 cable are the best all around jump ropes to practice and learn double unders.
How do I choose the right length jump rope cable?
Ideally your jump rope cable should never be longer than your height plus an additional 3 feet. For example if you are 5'8" tall the longest your rope should be is 8'8" long. However, more efficiency is gained working towards a rope that is equal to your height plus 2.5 feet.
My arms tend to go wide when I attempt double unders. Should I get a longer cable?
People's arms tend to go wide because they are ALREADY using a rope that is too long for their body. A longer rope will drag on the ground causing friction and this causes people to push their hands wide to shorten the rope and clean up the pass through zone. It's better to start with our suggested standard length and work towards shorter ropes over time.
I'm in between sizes on your chart. Which size should I choose?
If you are between sizes on our sizing chart then we strongly suggest choosing the shorter length if your goal is to learn with proper form and technique. If proper form and technique are not your goals and you would rather make an easier time of it then choose the longer option.
