Braid to Fluorocarbon Chart
Braid leaders are usually about half to two-thirds of the braid's labeled pound test. Check the spool before you buy.
Quick answer
Leader pairing
Common leader range
10–13 lb
A common pairing, not a strength formula.

The pound-test table is a field approximation. The United States does not publish one diameter for each pound test. Approximate only. Check the spool label before you match a leader or fill a reel.
