Two angler fly fishing which is made easier when using the best fly fishing leaders
Whether you are casting or presenting you fly, using a good fly fishing leader will help you out a lot. These two clients of mine are enjoying some great trout water.

I’m going to go over the topic of the best fly fishing leaders and I’ll discuss which ones are best for different situations as well as for different fish. I’ll also discuss things like strengths, types, and which lengths are best. As with all our articles, you are getting the best information because you’re getting it from a veteran fishing guide’s perspective.

Join me as I delve into the world of tapered fly leaders, breaking it down to the essentials that every new and intermediate fly fisherman should know.

Whether browsing through a fly shop or exploring online options, the sheer variety of choices of fly leaders can be overwhelming. Honestly, you don’t always get the best advice from stores and from other websites when it comes to fly fishing leaders.

What Is A Tapered Fly Leader?

A tapered fly leader is the section of the fly fishing setup that attaches to your fly line and goes between your fly line and your tippet, or your fly?

A tapered leader is just that, it’s tapered, which means it’s thick on one end and thinner on the other end with a gradual and smooth tapering between the two ends. This is like this for very good reason.

This picture shows the a leader and the clear diameter difference of the thick butt end and the thinner tip section.
This picture shows the a leader and the clear diameter difference of the thick butt end and the thinner tip section.

On one end of the leader it is thick, and this is called the butt section, which attaches to your fly line. I tell my clients, this is like a clear extension of your fly line.

On the end of the leader that you tie on your fly fishing tippet, or your fly, it will be thinnest.

The thin section needs to be thin enough that it will not be seen by the fish since thick lines can deter them from biting, yet, it must also be thick enough so that you don’t keep breaking off the fish.

If you are not sure how thick or strong your leader should be, don’t worry, I’ll explain below.

Do You Need A Tapered Leader For Fly Fishing?

I’ve heard the question asked before, do you need a tapered leader for fly fishing?

Yes, you need a tapered leader to help you cast your fly further and more accurately. A tapered leader also helps extend the leader so the fly lands far enough away from the thick fly line so the fish doesn’t see it.

Tapered leaders are even more important when casting into the wind. Unless you are an exceptionally good caster, casting a straight non-tapered line and fly into the wind would be nearly impossible to straighten the leader out. Basically, the fly and leader would land in a pile on the water, which is not what you want.

A tapered leader also prevents tangles in the leader and it prevents the leader and the fly line from tangling.

So What Tapered Leaders Do You Need?

You will need different-sized leaders for different flies, and for different casting situations, and even for different sized fish.

Leaders and tippets are rated in both the “X system” and the “pound test system”.

As an example, a 5X leader is about 3 pound test (it varies slightly by brand), and a 1X leader is thicker and closer to 12 pound test.

Don’t ask me why they rate it this way, it’s been like this since the caveman days, or before I was born anyways, and quite honestly, my opinion is that it is a really dumb way of rating lines.

If the X rating confuses you don’t worry, all fly leaders also have the pound test rating listed on the package and spool.

Fluorocarbon or Nylon Leaders?

Let me keep this simple for you, I always use nylon leaders (monofilament) for surface fishing, and I always use fluorocarbon for subsurface fishing.

You could use the less expensive nylon leaders with a fluorocarbon tippet, however, I have found that leader-to-tippet knots are not as strong when you mix fluoro with nylon, especially when using very light tippets.

The advantages of fluorocarbon for subsurface fishing are:

  • It’s more invisible to the fish below the water.
  • It sinks, which is why I don’t use it for surface fishing.
  • It’s abrasion resistant, so it’s less like to get nicked and scaped or cut on rocks.

What’s The Loop For On Your Leader?

Most fly leaders have a pre-tied loop in the butt section which is meant for easy changing using a loop-to-loop connection provided that your fly line also has a built-in loop.

The knot used for the loop on a leader is called a Perfection Loop Knot.

How Long Should A Fly Fishing Leader Be?

The fly fishing leader should be 9 feet long for most fly fishing methods. Keep in mind that normally you will be adding 20 to 30 inches of tippet to the end of yout leader making the overall lenght of a 9 foot leader about 11 feet long.

Fly fishing leaders are sold in 7 feet, 9 feet, 12 feet, and 15 feet.

  • Dry Fly Fishing Leader Lenght: A 9-foot is the standard leader size for dry fly fishing. However, some anglers prefer an 11-foot leader to keep the fly line farther away from the trout.
  • Nymphing Leader Length: A 9-foot fly leader is normal for most indicator nymphing setups.
  • Streamer Fishing Leader Length: A 7-foot leader is the preferred length for streamer fishing. Some anglers will use a 9 foot leader.

Fly Leader Sizes Per Method And Fish

You are going to use a different fly leader size for different situations and for different fish. So this is how I do it.

6x Tapered Leader – 3 Pounds: For Super Clear water

6x leaders are really thin, and I wouldn’t use them or recommend them except when fishing really clear water with very nervous trout, and even then I’d probable opt for a larger 5x with a 6x tippet instead.

5x Tapered Leader – 4 Pounds: A Must-Have for Delicate Situations

In certain scenarios, such as heavily fished areas, skittish fish, or when using small flies, having a 5x tapered leader in your arsenal proves invaluable. I use 5x fly leaders a lot for trout fishing.

5x is a fine diameter and great for subtle presentations and it won’t get noticed by cautious fish.

For most of my fly fishing for trout, I use 5x sizing for dry fly fishing and for nymph fishing for trout that are small to medium size, so that means trout that are 20 inches and under.

4x Tapered Leader – 6 pounds: The All-Purpose Workhorse

The 4x tapered fly leader is the go-to choice for most fishing situations and when the are larger trout involved. This is likely the most popular size for most new and intermediate fly anglers.

And since, I tend to use tippets that are one size smaller on all my leaders, I also use a lot of 4x fly leaders. I’ll discuss that more below.

4X (6 pound) strikes a balance between strength and versatility, allowing you to make confident hook sets without worrying about break-offs. FYI, if you are breaking off fish on the hook-set the problem is often your hook-set, and not the leader.

The 4x leader accommodates the majority of fly sizes with ease. It is good for larger dry flies and for nymph fishing.

Leveling Up With 3x – 8 Pound Tapered Leaders

When targeting larger trout, and bass, particularly during active feeding seasons like summer and fall, upgrading to a 3x tapered leader provides that extra bit of assurance.

Not only does it handle bigger flies effectively, but it also minimizes line twisting which is more common with dry flies on thinner leaders, ensuring a more enjoyable fishing experience.

Best For:

  • Trout: I rarely use 3x for trout unless im fishing large trout in large rivers.
  • Steelhead: I will use 3x when fishing for great lakes steelhead in small to medium-sized rivers or in clear water. Often combined with a 3X tippet and my steelhead fly leader setup which you can see at that link.
  • Bass: The is a good size for slow moving streamers, and surface flies for bass fishing.

Streamers and the Power of 2x Tippet – 10 Pound Test

This is a good size to use for steelhead, bass, and streamer fishing for trout.

Best For:

  • Streamer Fishing: This is a good size leader for streamer fishing with large streamer for trout and great lakes steelhead.
  • Steelhead: I use a 2x fly leader for larger great lakes steelhead rivers, and on small west coast steelhead streams.
  • Bass: Good for larger Bass streamers and when fishing bass in weeds.

Streamers and the Power of 1x Leaders – 12 Pounds

For those moments when you’re exclusively focused on enticing fish with big streamers for steelhead, salmon, pike, and bass, using 1x tippet can be a game-changer. These hefty flies can entice aggressive strikes, and the strength of 1x tippet ensures you won’t lose your trophy fish or your fly due to line breakage.

Steelhead: I use a 1x fly leader for larger great lakes steelhead rivers, and on most west coast steelhead streams.

Best Leaders For Salmon And Steelhead: Rio Steelhead/Salmon Leaders

When fishing for salmon and big west coast steelhead, I use the Rio Steelhead/Salmon Leaders.

I’ve found the Rio Steelhead/Salmon Leaders to be the best leader for targeting steelhead and salmon and that are all I use when guiding.

The impressive combination of strength, durability, and precision these leaders provide is unparalleled. Not to mention, most leaders do not come in these larger sizes, 10, 12, 16, and 20 pounds.

What sets these high-quality leaders apart is their ability to withstand the power of large, forceful fish. Their exceptional knot strength, resistance to wear, and tapered design are all elements that convince me that the Rio Steelhead/Salmon Leaders are still the best option for salmon and steelhead.

One particular feature I cannot stress enough is the superior abrasion resistance. As anyone familiar with steelhead and salmon habitats knows, these fish thrive in rough, rocky environments that can be harsh on your gear. However, Rio Steelhead/Salmon Leaders are designed to handle these conditions.

These leaders can endure contact with sharp rocks, submerged logs, and other hazards without compromising their integrity.

Based on my experience, I highly recommend the Rio Steelhead/Salmon Leaders to any angler.

This is a 60 pound great lakes musky I caught when I guided for musky.

Having been an avid angler for years and did you know, I also guided for musky for 17 years with my person best musky being around 60 pounds.

So, I can’t express enough how much I love and highly recommend RIO’s Pike/Musky Leaders.

These leaders have been an absolute game-changer for me when it comes to pursuing toothy species like Pike and Musky for my clients.

What sets these leaders apart is their ultra-stiff nylon construction. They are specifically designed to handle the aggressive nature of these powerful predators, providing the strength and durability needed for intense battles.

These leaders come with a convenient twist clip tied to the end, making rigging quick and hassle-free. Trust me, when you’re out on the water and you need to change your setup in a flash, these leaders will save you precious time.

If you’re targeting those trophy-sized beasts or using fast sinking lines, then the Pike/Musky Magnum leader is the way to go. With a 4.5-foot length and a robust 40lb knottable wire option, it’s specifically hand-tied to handle the largest flies and the demands of aggressive fish.

RIO offers the Pike/Musky Stealth leaders in 6-foot lengths with 60lb or 80lb fluoro options, these hand-tied leaders are perfect for making stealthy presentations to pressured Pike and Musky. The absence of wire in these leaders is awesome.

Do You Need To Add A Tippet To Your Fly Fishing Leader?

Yes, you do need to add a tippet section to your fly fishing leader, or at least you should since there are some benefits to adding a tippet.

The way I explain tippet to my new fly fishing students is the tippet goes on the end of your leader, so basically, it’s the tip of your leader where your fly is tied.

The are a couple of reasons for a tippet.

A tippet is not tapered, it’s all one diameter, and therefore you can cut off and tie many flies onto a 12 to 30-inch tippet, and the line will never get any thicker. Each time you cut a fly of and tie a new on one you lose about 2 to 3 inches of line.

If you don’t use a tippet and you tie your flies directly to your tapered leader, after changing five or ten flies, you will cut into your leader, and eventually, your leader where you tie the fly will get too thick, which means the fish might see it. The leader will also eventually get too short.

Using tippets also greatly extends the life of your leader. I will often use the same leader all season, and I tie on a crap load of flies, and my leader stays in good shape because I keep adding new tippets with either a knot or a tippet ring.

How long should you’re tippet be?

Determining how long your tippet should be will depend on the method you use, but as a general rule, I like to use a tippet that is about 20 to 30 inches.

  • Dry Fly Tippet Lenght: Your tippet for dry fly fishing should be 24 to 30 inches.
  • Nymphing Tippet Lenght: Your tippet length for nymphing should be 20 to 30 inches
  • Streamer Fishing Tippet Lenght: 16 to 24 inches

In conclusion, I hope you’ve found this guide informative and empowering. Remember to keep these principles in mind: choose leaders and tippets based on the fishing conditions, match the sizes appropriately, and select reliable brands like Rio Power Flex for optimal performance.

With these guidelines, you’ll be well-equipped to tackle a variety of fishing situations and make the most of your fly fishing adventures.
