How to Choose the Right Size Fly Fishing Leader & Tippet

When the fish aren't striking, chances are it's not your fly or your casting - it's your leader.

Choosing the appropriate fly fishing line, leader, and tippet - and knowing when and how to use it - is possibly the most intimidating component of fly fishing for novice anglers. When selecting a fly fishing leader, there are three crucial factors to consider: the length of the leader, the diameter of the butt section, and the diameter of the tippet (or level portion at the end of the leader).

What is a leader?

Fly fishing leaders are a tapered section of line that is immediately joined to your thick, colorful fly line by a loop-to-loop connection or knot. The purpose of the leader is to provide a smooth transition from the fly line to the fly, ensuring accurate and delicate presentations. Fly leaders are always tapered, with one end thicker than the other. This taper is crucial because it helps transfer energy and momentum from the rod through the line and finally to the fly during casting, allowing for precise and controlled delivery.

Typically, you’ll find leaders in standard lengths of 7.5 feet, 9 feet, or 12 feet. The choice of length depends on various factors such as the type of water you’re fishing in, the species of fish you’re targeting, and the environmental conditions. Shorter leaders (7.5 feet) are often used in situations where accuracy and strength are needed, such as in windy conditions or when casting larger flies. Longer leaders (9 feet) are preferred in clear water or when fishing for more cautious fish, as they allow for a more delicate presentation and reduce the chance of spooking the fish.

What is tippet?

Tippet is a specific type of fly fishing line that maintains the same weight, poundage, and diameter throughout its entire length. It is designed to be used in shorter segments at the end of your leader.

In fly fishing, the leader and tippet combination is essential for a precise and delicate presentation of the fly. The tippet serves as the final section where the fly is tied. Every time you change or lose a fly and need to snip off the extra line, you reduce the length of your leader. Over the course of a fishing session, your leader can become quite short due to snagging trees, catching fish, and changing flies.

Attaching a portion of tippet to the end of your leader is a simple and effective technique to extend the length of your line without having to replace the entire leader. This not only conserves your leader but also allows for quick adjustments to your setup. Using tippet also ensures that the transition from the leader to the fly remains smooth and natural, maintaining the desired presentation and avoiding spooking the fish.

How to use tippet

When changing flies, the thinnest end of the line is clipped shorter and shorter. Because leaders are tapered, you move closer and closer to the thickest area of the leader with each clip and at some point will become inefficient, becoming short, thick, and stubby. Most of the time, your leader will be too thick to tie a secure knot with.

If your leader becomes too short it may be faster to cut a segment of thinner tippet from a spool and tie it onto your existing leader rather than unpacking a new leader and spending the time to replace the old one. You can tie on a few feet of tippet and manually create your own tapered leader in just a few minutes.

Different types of leader & tippet

When it comes to fly fishing leaders and tippets, there are two main types categorized by the material used: monofilament and fluorocarbon.

Monofilament Leader & Tippet:

Characteristics: Monofilament tippet is known for its versatility and affordability. It is made from a single strand of nylon, which gives it a range of benefits that suit various fishing scenarios.
Strength and Durability: Generally, monofilament tippets have a lower pound test compared to fluorocarbon, making them suitable for lighter, more delicate presentations.
Applications: Due to its flexibility and stretch, monofilament is ideal for most species and is widely used by anglers in freshwater and saltwater environments. It’s especially effective in situations where you need a tippet that floats well, such as when dry fly fishing.
Cost: Monofilament is typically more budget-friendly, making it a popular choice for beginners and seasoned anglers alike.

Fluorocarbon Leader & Tippet:

Characteristics: Fluorocarbon tippet is made from a dense material that is almost invisible underwater. This low visibility can be a significant advantage in clear water and when targeting wary fish.
Strength and Durability: Fluorocarbon is stronger and more abrasion-resistant than monofilament, which allows it to handle tougher conditions and larger, more aggressive fish. It also sinks faster, making it suitable for nymphing and other sub-surface fishing techniques.
Applications: Given its durability and strength, fluorocarbon is often reserved for challenging fishing scenarios that require a more robust line. It excels in environments with rocky or debris-laden bottoms where abrasion resistance is crucial.
Cost: Fluorocarbon is more expensive than monofilament, but its enhanced properties can justify the higher price, particularly in demanding fishing situations where performance and reliability are critical.

Understanding the differences between monofilament and fluorocarbon tippets will help you choose the right material for your fishing needs. Whether you’re looking for a cost-effective, versatile option with monofilament or a durable, low-visibility choice with fluorocarbon, selecting the appropriate tippet can significantly impact your success on the water.

What size leader and tippet should I use?

Anglers of all skill levels struggle to know when to use 6X tippet instead of 4X or a 7.5 ft leader instead of a 9 ft leader, and regrettably, some of our catching problems can be due to the line we're using. Here are a few things to consider when deciding what size tippet and leader you should be using.

Leader Length: Leader length is determined by three factors: water conditions, the type of fly line being used, and the species of fish you are trying to catch.
- Water Conditions: The clarity, depth, and temperature of the water play a significant role in deciding the length of the leader. In muddy or turbulent water, shorter leaders are often preferred as fish are more opportunistic and less likely to be spooked. Conversely, in clear, shallow, or slow-moving water, longer leaders are necessary to present the fly delicately and avoid detection by wary fish.
- Type of Fly Line: The type of fly line you use also influences the appropriate leader length. Sinking lines are typically paired with short leaders (3-5 feet) to ensure the fly sinks quickly and stays deeper in the water column. This setup is ideal for reaching fish that are holding below the surface. On the other hand, floating lines generally require longer leaders (7-12 feet) to facilitate a natural drift and presentation of the fly on the water's surface.
- Target Species: The behavior and feeding habits of the target species can dictate leader length. For example, fish that are easily spooked or those that feed in clear, still waters often require longer leaders to avoid detection. Conversely, species that are more aggressive or feeding in murky, fast-moving waters can be effectively targeted with shorter leaders.
Butt Section Size: For a smooth transition from the fly line to the leader, it is crucial that the butt section is the right size.

Importance of Butt Section Size: Leaders with butt sections that are too small or too large in diameter will tend to hinge, jerk, or fail to lay out smoothly. This can negatively impact your casting accuracy and the presentation of your fly, making it less effective in attracting fish.
Diameter Proportion: In general, the leader butt diameter should be approximately two-thirds of the diameter of the tip of the fly line. This proportion ensures that the energy from your cast is transferred efficiently from the fly line to the leader, allowing for a more controlled and precise presentation of the fly.
Specifications for Trout Fishing: For normal trout fishing, the leader butt should have a diameter between .019 and .023 inches. This range provides the necessary stiffness and strength to turn over the leader and deliver the fly accurately.

Tippet & Leader Weight/Size

Tippet and leader weights/sizes are usually described in X's. The X size of a line describes the diameter of the line as it relates to a scale of "11". This inverted scale is much like a wire gauge scale. As the size of the tippet or leader gets larger, the X rating gets smaller. For example, a 0X tippet is .011" in diameter. A 5X tippet is .006" in diameter. The X and the size in thousandths of inches always add up to 11.

To work correctly, small flies require small diameter tippets/ leaders, whereas larger flies require larger tippets/ leaders. In general, dividing the size of the fly by three offers a decent approximation of the line's "X" rating. A size 12 fly, for example, is usually fished with a 4X tippet/ leader, whereas a size 18 fly is usually tied to a 6X tippet/ leader. Use one size smaller for extremely clear water and skittish fish. Use a size larger for muddy water or night fishing. When fishing for larger species, this "Rule of Three" does not apply. A 20-pound salmon, for example, may eat a size #12 nymph pattern that you can easily cast with a 6-weight rod and 4X, 6-pound tippet. So species size is also a condition.

1X	.010″	13.5 lb.	Bonefish, Redfish, Permit
2X	.009″	11.5 lb.	Large & Smallmouth Bass
3X	.008″	8.5 lb.	Bass & Large Trout
4X	.007″	6 lb.	Trout
5X	.006″	4.75 lb.	Trout & Panfish
6X	.005″	3.5 lb.	Trout – Easily Spooked Fish
7X	.004″	2.5 lb.	Trout & Panfish / Delicate Presentations
8X	.003″	1.75 lb.	Trout & Panfish / Small Flies

Choosing the right leader and tippet is a critical aspect of fly fishing that can greatly influence your success on the water. From understanding the appropriate leader length for different conditions, to selecting the correct butt section size for smooth casting, and knowing the differences between monofilament and fluorocarbon tippets, these components are essential for effective fly presentations.

Whether you're a novice angler just starting out or an experienced fisherman looking to refine your technique, mastering the selection and use of leaders and tippets will enhance your fly fishing experience. Remember, the key to better fishing often lies not in your fly or casting technique, but in the finer details of your setup. Equip yourself with the right knowledge and gear, and you'll be well on your way to more successful and enjoyable days on the water.
