Line Strength

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….”
