What Size Leader Should I Use for Fly Fishing?

Fly fishing is a popular sport that requires the use of a specialized rod and reel. The type of leader used for fly fishing can be an important factor in the success of your outing. The size of the leader you choose to use can affect the presentation of your fly, as well as the fish’s ability to detect it.

When choosing a leader for fly fishing, there are several considerations that should be taken into account. Firstly, consider the type of water you will be fishing in.

Different types of water require different sizes and strengths of leaders. For example, if you are fishing in fast-moving water, a thicker leader is necessary to ensure that your flies don’t get washed away before they reach their intended Target. Conversely, if you are fishing in still water, a thinner leader is preferable to make sure your flies are presented delicately and without excessive drag.

Another factor to consider when selecting a leader for fly fishing is the type and size of fish you will be Targeting. If you are Targeting larger fish, such as salmon or steelhead, a heavier leader is recommended so that it can withstand the powerful strikes from these predators. On the other hand, if you are Targeting smaller panfish or trout, a lighter leader may be more appropriate as it will present your flies more naturally and provide less resistance when fighting smaller fish.

The last factor to take into account when selecting a leader for fly fishing is personal preference. Many anglers prefer leaders with different lengths and tapers based on their own experience and technique. Experimenting with different sizes and tapers can help find out which one works best for each individual angler’s style and purpose.


In conclusion, when selecting a leader for fly fishing there are many factors to consider including water type, Targeted fish species, and personal preference. Knowing how each factor affects the size and strength of your leader can help ensure that you have chosen an appropriate one for your next outing.
