Type of Fly Lines for Trout 

In order to choose the best fly fishing line for your trout fishing, it is important to know the types of fly lines available. Understanding the functionality of each type of fly line for trout will help you to make an informed choice.

There are two major types of fly lines for trout which are double taper fly lines and weight forward fly lines. 

Double Taper Lines

When it comes to fly fishing for trout, double taper lines are the go-to fly fishing lines for most fly anglers. Also known as DT lines, double taper fly lines are fly lines that are made up of a front taper and a back taper.

The double tapering of the line allows you to use both ends of the line for casting flies. Double taper fly lines are also best for delicate presentations, due to their long heads that make it easy to form long loops.

Weight Forward Lines

Weight forward (WF) lines have increased in popularity in recent times due to their functionality and reliability. One of the reasons for this popularity is the thick and heavy head which makes it easy to use them over a long casting distance.

The way it works, a weight forward line tapers into a running line, thereby forming a shooting head that allows for a long cast. A WF line is also suited for casting large flies, nymph fishing as well as saltwater fishing. 

Asides from the two main types of fly lines for trout fishing, there are other types of fly lines made for specific functions. These fly lines are shooting heads that are used for sea trout fishing and special nymphing lines for nymph fishing of trout.  

Things to Consider When Buying Fly Lines for Trout

In order to get the right fly line for trout fishing, It is important to consider certain factors. These factors are highlighted below. 

Where Will You Use the Fly Line

The location and type of water body where you are going to use the fly line is a factor to be considered. You can choose between a sinking line and a floating line.

Floating fly lines are designed for fishing at the surface level. This makes them suitable for fishing with nymphs and streamers. If you are trout fishing in shallow water, then a floating fly line is a good choice.

Sinking lines on the other hand are designed to sink underwater. This makes it best for trout fishing in deep waters such as ponds and lakes. 

What Style Will You Be Fishing 

The style of fishing is another thing to consider when choosing a fly line. If you are doing dry fly fishing, a double taper fly line is your best choice.

If you are fishing streamers in a wide body of water, a weight-forward fly line works best. If you fishing with a nymph setup, a trout nymph fly line is the best choice for you. If you are fishing for steelhead, choose a shooting head. 


The size of a fly line might range from 1 to 12. When choosing a line, it is important to match its size with the size of your fly rod. 


Weighting here refers to the thickness of the fly line, and not the weight. The weighting of your fly line determines the type of casting you can use.

Weight forward lines are usually thick making them reliable for long casting. Tapered fly lines, on the other hand, are perfect for the delicate presentation of small light flies. 


Getting the right fly line for your trout fishing will always make a whole world of difference. Ensure to look out for features like size and weighting before making a choice.

You should also consider factors like your fishing style and the location where you will be fishing. In addition, it is important to combine your fly line with a reliable fly rod for the best results.

Also, ensure to wear protective clothing and a pair of wading boots at all times.
