Estimate jump rope cable length from height, or reverse the sizing rule for an existing rope. The default allowance is 36 inches; handles are excluded from cable length.

Use the default allowance or enter a personally tested allowance.

The default height + 36 in rule estimates cable length, excluding handles. It is a starting point; test your rope before cutting.

Sizing and handle settings

36 in is the manufacturer starting rule, not a universal fit. Other values must be personally tested.

Blank means no reduction. Test first; a cut is permanent.

Blank omits the tip-to-tip estimate. Required when checking tip-to-tip length.

Jump Rope Length Formula

The following two example problems outline the steps and information needed to calculate the Jump Rope Length.

JRL ≈ H + 36
  • Where JRL is the estimated cable length, excluding handles (in)
  • H is your total height (in) 

As a starting estimate following RX Smart Gear sizing guidance, add 36 inches (3 ft) to your height for cable length, excluding handles. Check the cable ends using your rope maker’s method and test the rope before cutting. Hand position, technique and product design affect fit; the height rule is not a guarantee.

How to Calculate Jump Rope Length?

The following example problems outline how to calculate Jump Rope Length.

Example Problem #1:

  1. First, determine your total height (in).
    • Your total height (in) is given as 60.
  2. Finally, calculate the Jump Rope Length using the equation above: 

JRL = H + 36

The values provided above are inserted into the equation below and computed.

JRL = 60 + 36 = 96 (in)

Example Problem #2: 

For this problem, the variables required are provided below:

your total height (in) = 72

Test your knowledge using the equation and check your answer with the calculator.

JRL = H + 36 = ?
