Knot Strength Chart
Quick reference for fishing knot strength retention by line type. Use this chart to choose the right knot for your setup.
Universal Knots (All Line Types)
| Knot | Mono | Fluoro | Braid | Best For |
|---|---|---|---|---|
| Palomar | 95-100% | 95-100% | 95-100% | Hook, lure, swivel — most versatile |
| Uni Knot | 90-95% | 85-90% | 85-90% | Hook, lure, line-to-spool |
| Improved Clinch | 85-90% | 80-85% | ⚠️ Avoid | Hook, lure (mono only) |
| Trilene Knot | 90-95% | 90-95% | ⚠️ Not ideal | Hook, lure (mono & fluoro) |
Strength percentages are approximate and vary by line brand, diameter, and how carefully the knot is tied. Always wet the knot before tightening.
Leader Connection Knots (Braid to Leader)
| Knot | Strength | Difficulty | Profile | Best For |
|---|---|---|---|---|
| FG Knot | 90-95% | Hard | Thinnest — casts through guides | Braid-to-fluoro, long leaders |
| Double Uni | 85-90% | Easy | Thicker — may catch in guides | Quick connection, all line types |
| Alberto Knot | 85-90% | Medium | Medium — good compromise | Braid-to-leader, versatile |
| Surgeon's Knot | 75-80% | Very Easy | Thickest — use for short leaders | Quick fix, emergency ties |
The FG knot is the gold standard for braid-to-leader connections. It's hard to tie but worth learning — it casts smoothly through rod guides and has the highest strength retention.

Frequently Asked Questions
Knot strength is the percentage of the line's rated breaking strength that remains after tying a knot. A knot with 95% strength means you lose only 5% of your line's capacity. A weak knot (70%) loses 30% — so 10 lb line breaks at 7 lb. This matters when fighting fish near structure or using light line. Always test your knots by pulling hard before casting.
The Palomar knot is widely considered the strongest and most versatile — it retains 95-100% of line strength in monofilament and fluorocarbon. For braided line, the Palomar and Uni knots both perform well. The FG knot is the strongest for connecting braid to a fluorocarbon leader, retaining 90-95% strength. See our knot strength chart above for specific numbers by line type.
For braid-to-hook/lure, use the Palomar knot (95%+ strength). For braid-to-leader, use the FG knot (90-95%) — it's the thinnest and strongest connection. The Double Uni knot is easier to tie and still strong (85-90%). Avoid the clinch knot with braid — it slips. Our leader calculator can help you choose the right leader setup for your braid.
Most knots work on both, but fluorocarbon is stiffer and has more memory, so you need to wet the knot before tightening to prevent friction damage. The Palomar, Uni, and improved clinch all work well on fluorocarbon. The Trilene knot is specifically designed for fluorocarbon and retains 90-95% strength. Always moisten the knot before pulling tight.
After tying, pull the line hard with steady pressure — don't jerk. If the knot holds, it's likely strong. If it slips or breaks at the knot, retie. A good knot should break at or near the rated line strength, not slip. Practice tying knots at home so you can tie them quickly on the water. Check our line strength calculator for the right line test for your target species.
