We all know how confusing the sizes of the different makes are.
Hopefully one day we consumers are strong enough to tell the producers to use only ONE size (total m²).
But until then, here is a table to have a better overview:

wrong.
AB 6.3 is like an 8.5 ARX
AB 8.3 is like an 11.5 ARX
AB 11.8 is like an 16.2 ARX

You are right, now that you are mentioning it!
The Naish sizes are totally wrong!
I will look for a better one.

Was this "mistake" by purpose of Cabrinha!?!?! We'll never know...

I tried a Beginner-Kite: Cabrinha C 111, 8.5 qm, 2-liner, length of bar: 66 cm, from 2002. The leashes (mostly green and red) weren`t equal. The difference was between 5 and 7 cm. I would like to mention ist, `cause you can get involved into dangerous situations. So take care

the sizes are only one factor that bilt the power of the kite the wipika ab 8.4 =arx 9.5-10.5 and not 11+ ,the f-1 15.1 =arx 12.5-13 so dont make a mistake and check the kite wind range by your self
