Punch-bag length and optional weight

Enter the measurements above to calculate punch-bag length and optional weight.

How the calculation works

For this tool, the calculation is recommendedBagLength=userHeight×bagLengthFactor; recommendedBagWeight=userWeight×bagWeightRatio when both optional weight inputs are supplied. That produces punch-bag length and optional weight without borrowing assumptions from unrelated calculators.

Worked example

Example: User height = 175 cm; Bag-length factor of user height = 0.3; User weight = 75 kg; Bag-weight-to-user-weight ratio = 0.2. Result: Recommended Bag Length = 52.5 cm; Recommended Bag Weight = 15 kg.
