Fishing line problem? What is the length of the sub-line?

The auxiliary line you asked refers to the fresh water auxiliary line.

The so-called sub-line length is the length of your sub-line connected to the eight-character ring or the quick pin to the hook.

Generally speaking, the length, 15 or 20cm, refers to the length from a single hook to a splayed ring.

Because you use the desktop fishing method, there are two hooks, which are different in length after being tied, but when the hooks are tied, they are a line, so there is a dividing ruler to measure the length.

Usually, the length of the sub-line is less than 20 cm, and the total length of the two hooks is 40 cm when they are not folded in half.

According to the length of the bottom hook, the distance between the upper hook and the lower hook is determined by yourself, usually 3-5 cm.

The lengths mentioned are all tied lengths, so when you measure with a dividing ruler, there is still a little extra line. The extra dotted line is used to make up for the material you are tying and the extra thread that needs to be cut off.
