The Perfection Loop Knot is famous for its slim profile and how it allows quick leader changes with a loop-to-loop connection.
After a bit of practice, you’ll find the perfection knot, one of the quickest loop knots around. It’s a popular fly fishing loop knot, so make sure you know how to tie it before going after those big trout, salmon, and steelhead.

How to Tie a Perfection Loop

Here’s a step-by-step guide to tying a perfection loop:
- Gather your doubled line with both hands and cross them, so you form a loop. The tag end should be on the backside of the loop.
- Pull the tag end around the front of the loop and pinch it with your index and thumb. You should have two loops, the original back loop, and a new front loop.
- Take the tag end, wrap it around the back of both loops, and then place the line between the first and second loops. I like to hold the tag end by using my middle finger against the top of my index finger.
- To complete the perfection loop knot, you’ll need to push the front loop through the back loop. Use your index finger to pull the loop and start cinching down your knot.
- Before you fully cinch it down, get it moist with water or saliva.
- Complete your perfection loop by pulling the loop and the mainline, letting the tag end free to move.
- Clip the tag end, and you’re set. Congrats on creating a perfection loop knot!

Strength
It was shown to hold up to nearly 95% strength in some tests. Many variables have to go right for this (or any knot) to work correctly, including a perfect knot tie, quality materials of line, even pressure when cinching, and more.
Tips
- Many of the online animations make the perfection loop knot overly complicated. After you pinch your first loop, I think about it as a clockwise loop, clockwise one more time to create the doubling of loops, pull the front loop through the back, and you’re done.
- When you tie the perfection loop, then cinch it down, leave the tag end free so it can lock in place. The tag should be perpendicular to the mainline to know it’s fully locked.
- This is not a knot that can be untied easily. It’s better to cut and retie if necessary.
- Before cinching down the perfection loop, select the loop size you want by using one hand to open the loop and the other to hold the mainline.
- Make sure the tag end is in the rear and pointing perpendicular when making this knot.
Uses
- This is an excellent knot for creating a loop-to-loop connection.
- It’s a popular fly knot. If you’re getting serious about fly fishing, then this is a fly line loop knot that’s mandatory for you to know.
- You can use it with both monofilament and fluorocarbon.
- You can use the perfection fly loop knot for lures and attach your fly or lure to your line. These types of connections allow for a more lifelike movement in the water.
- This knot is excellent for tying premade leaders to lures or hooks to connect to a swivel or clip. This can be used to quickly change your hook or bait type/size for different presentations.
