- Handler hand height — Required
- Dog attachment point height — Required
Dog lead length
Enter the measurements above to calculate dog lead length.
How the calculation works
V16 calculation: leadLength=sqrt(desiredRadius^2+(handlerHeight-attachmentHeight)^2). Canonical CMS units are used for numeric constants.
Worked example
Example: Maximum desired roaming radius = 60 cm; Handler hand height = 175 cm; Dog attachment point height = 50 cm. Result: Lead Length = 138.65 cm.
