Frequent Question:
How do you determine the size of kite line?
Stevef says:
“I have two general formulas:
1. The flying line should have a breaking strength of about three times total area in square feet, times 1.2 (add 20% ‘just in case’)
2. Line strength = (1/5 x surface area in square feet) x (Maximum wind velocity in mph) x 1.2 (add 20% ‘just in case’)
I usually go by #1 just because it is easier. Remember, this is just a general guideline. Other things come into play, like wind conditions, age & quality of line, number of knots, type of kite, attached line laundry, etc….”
