Recommendation on how to choose kite line for your kites!
Please choose the right kite line for your precious kites. This is important!
Whenever you fly a kite, please make sure that the line could hold your kite and the wind.
The followings are recommendations of line/kite match ( kites are measured by wingspan):
Kites below 3ft: 50lb~100lb
Kites within 3~4.5ft: 100lb~150lb
Kites within 4.5~7.5ft: 150lb ~ 250lb
Kites within 7.5~9ft: 200lb~400lb
Kites above 9ft: >350lb

Recommendation above are for common case.
However, things may vary according to different kinds of kite shapes.
For example, delta kites of 6ft only needs 200lb kite line, but Rokkaku (hexagon kite) of 6ft needs 400~500lb kite line because their venting methods are so different.
Also, kite spar's material, the vent part of kites... all details of kites will lead to the consequences of how you choose kite line for your kite.
The wind is also the critical part.

All in all: KNOW YOUR KITES and CHOOSE THE RIGHT LINE FOR THEM!!!
