The best fishing line for trout is 4 to 6 lb, low visibility and high sensitivity line such as Seaguar Blue Label FLuorocarbon.

Trout fishing can be a very fun experience when you know what you are doing and are using the correct equipment for trout fishing. Trout are normally found in clear streams or lakes, so it is good to know you won’t be fishing in extremely choppy waters to catch them.

As you probably know hence why you have come here there are several different lines when it comes to fishing and they are all great but some work better than others in regards to what type of water you’ll be fishing in and what type of fish you are trying to catch.

Some lines that are heavier for example are good for catching much bigger fish, Trout, for example, is a smaller fish and a lighter weighted line would be better for catching them. Not that the line automatically makes you a successful trout catcher but it will certainly impact the ease in which you have when catching them. 

As mentioned, catching Trout can be a very fun experience for those who enjoy fishing but it is important to have the right equipment, hopefully, with the information provided below, it will put you in the best position when it comes to making your final decision on which line is best for use when catching Trout

I have seen too many anglers lose fish because they have picked poor quality line. All of this information is based on my own fishing experiences and insights.

Let’s begin.

How We Rate Products

I thoroughly review all products to measure their performance, durability, and value for money. This is done through bench and field testing to check how the product performs. This testing results in an overall score that I give to all products. All metrics are scored out of 5.


The performance score is how well this product fulfills its primary purpose. Does it have all the features and optional extras you need to catch the target species? We also interview expert anglers on their experience to build a broader and more comprehensive view on the performance under multiple conditions.

  • Test 1: Confirm that the max drag meets the manufacturer’s specifications.
  • Test 2: Test the maximum casting distance using a 1.0-ounce lure.
  • Test 3: Test the accuracy by casting 10 times into a 3 ft diameter circle at 30 yards.
  • Test 4: Check the versatility and the ability to handle multiple uses by field testing with 3 different lures and baits.


Durability refers to how long the product will continue functioning. I twist, bend, and break all the products to check their longevity. This score is for the materials of construction, the quality of the workmanship, and the servicing requirements. There are also bonus points for manufacturers’ warranty.

For products that we can’t test for long enough, we also consult with experts who have been using them for multiple decades to judge their longevity.

  • Test 5: Pull it apart to check the grease and oil levels, how difficult it is to maintain, and whether any sand or salt has deposited after use in saltwater.

Value for Money

The final aspect of the scoring system is the price or, more specifically, the value for money. Value for money is a comparison against the closest alternative products, both by the same manufacturer and other brands.

Overall Score

Finally, I average the three scores of performance, durability, and value for money to give the overall score of each product reviewed.

1. Seaguar Blue Label  – Best Overall

When it comes to catching Trout the Seaguar blue label is one of the premium choices. Many experienced fishermen are huge fans of using this line. The material used for its making is Fluorocarbon making it a highly sensitive line.

It is important for catching Trout that the line you have selected is highly sensitive as Trout who when in lakes aren’t aggressive towards bait so it is important that you can feel even the faintest of nibbles when casting your line out.

Due to Trout in lakes being less aggressive it means that they are more hesitant when approaching things such as bait. That means it is important that the line you are using cannot be easily spotted by the fish causing them to not take a nibble on your bait. Luckily with the Seaguar line it is practically invisible for trout.


  • Fluorocarbon line makes it almost invisible to fish underwater.
  • I found it to be a very sensitive line which gives you additional warning to prepare to set the hook when a fish nibbles.


  • I didn’t think there was anything special about its abrasion resistance.

2. P-Line Floroclear – Best Fluoro Line

The P-Line offers complete knot strength making it the perfect line for you if that is what you are mainly looking for. It is a blend of Fluorocarbon and nylon which provides its durability and also its sensitivity.

It is also an incredibly easy line to cast which makes the whole process that much more enjoyable. It also provides zero stretch which is highly important when trout fishing as it makes the sensitivity all that more prominent. 

Due to its nature it is highly surprising that this line is an inexpensive one as the majority of fluorocarbon lines are on the expensive side. It also has a small diameter which makes it the perfect line when fishing for trout.


  • I think this line has a good combination of highly sensitive, strong, durable, and affordable.
  • Zero stretch.


  • The line can be known to tangle, which can be an absolute nightmare, especially if you are sight fishing for trout in clear water. The last thing you want is to get a tangle while you can physically see the fish you are chasing.

3. KastKing FluoroKote – Low Visibility

KastKing are a well known brand around the fishing world so it is no surprise that they make it onto this list. The FluoroKote line in question is an incredibly designed line at that. It is fully Fluorocarbon making it incredibly strong and also making it highly sensitive, which as you know is incredibly important when fishing for Trout. 

It is highly resistant to abrasions due to the material used to make it meaning that it can be dragged over rocks or other forms of debris that may be at the bottom of a lake without receiving damage which is highly important for all fishing lines.

It is practically invisible underwater thanks to its coating being a copolymer. Visibility is again of high importance when catching Trout as they are much more hesitant when taking a bite out of your bait and anything that could put them off will make them scurry away.

The line also provides zero stretch making it very useful to have in your bag if you go Trout fishing regularly.


  • Zero stretch
  • Highly sensitive
  • Durable
  • Practically invisible when underwater which will get you more bites.


  • I noticed some early warning signs of it having too much line memory meaning it will curl on the spool after a while.

4. Stren Fluorocast  – Most Abrasion Resistant

The Stren Fluorocast is a very popular choice for Trout fishing amongst experienced fishermen. As it again is made of fluorocarbon it is an incredibly strong line that also provides excellent sensitivity. 

It is also highly resistant to abrasions making it difficult to become damaged from usage or being dragged over debris. This is one of the most important factors when it comes to durability. It also is known to sink quickly, making your bait go deeper in much less time than if it was to sink at a lower rate. 

Underwater this is completely invisible due to its fluorocarbon making. This once again is important for Trout fishing as they aren’t aggressive towards bait and will swim away if they suspect the line. Fluorocarbon lines provide everything you need in regards to Trout fishing and should really look no further when it comes to making your final decision.


  • Durable
  • Sinks quickly
  • Sensitive
  • Strong
  • Invisible underwater


  • Has been known to twist.

5. Sunline Super FC Sniper Fluorocarbon – Most Durable

The Sunline Super line is an incredibly sought after line by experienced fishermen, it is fluorocarbon so you already know that it will be strong and durable making it much easier to reel in your catch. 

It is also highly sensitive because of its fluorocarbon making. Meaning it is perfect for catching Trout that are less aggressive in lakes where there aren’t specific territories. It is also incredibly abrasion resistant which of course adds to its durability and strength. 

Abrasion resistance is again an important factor for Trout fishing as you never know what type of rugged terrain you may end up dragging the line over. It also has Zero stretch which adds to its highly sensitive nature. 

Due to its strength the casting process is incredibly easy and much more enjoyable than if something was weak during the cast. 


  • Strong during the cast
  • Highly sensitive
  • Durable
  • Resistant to abrasions
  • Zero stretch


  • Been known to tangle.

6. Berkley Trilene Monofilament – Best Value for Money

The Berkley Trilene Monofilament line is an incredibly good line to have in your arsenal. It is highly durable which is to be expected with monofilament lines. These lines are a little bit more visible than fluorocarbon but not by a massive margin and should still work perfectly for Trout fishing.

It provides good knot strength which is a very useful feature. It is also a very easy casting line due to its monofilament nature. Like mentioned it offers low visibility. Visibility is important when fishing for trout in small areas as they won’t be aggressive to your bait.

It is also incredibly abrasion resistant making it strong and durable. This is important as if a line is weak and not resistant to abrasions you will notice it starts to wear the more you use it before eventually breaking.  


  • Abrasion resistant
  • Good knot strength
  • Durable
  • Strong
  • Easy to cast


  • Offers low visibility but is not completely invisible.

Berkley Trilene Big Game Mono Fishing Line

Overall Score – 5/5 ⭐⭐⭐⭐⭐

Berkley Trilene Big Game Monofilament Fishing Line
  • Available in Up to 10,800 Yard Spools
  • From 8 to 200 Pound Strength
  • Extremely Powerful
  • Shock Resistant

7. KastKing Superpower Braid – Best Braid Line

Normally a braided line wouldn’t be the best choice for fishing for Trout, however they are a good choice if you use a spinning reel. It offers an incredibly durable and strong finish which is of course always useful to have when fishing.

It is definitely one of the more abrasion resistant lines on the market today just by being a braided line. Abrasion resistance is one of the more important factors when it comes to longevity of the line and that is something that is provided when using this line.

It has low memory too which is brilliant in regards to preventing curls forming or from the line becoming tangled as this is one of the most infuriating things when it comes to fishing.

It is also incredibly sensitive as it has zero stretch making it easy to feel any little nibble that might occur. This is highly important when it comes to fishing for trout as they can be very passive in calm water meaning you will need to feel everything when fishing for them.


  • Zero stretch
  • Doesn’t tangle
  • Low memory
  • Strong
  • Durable


  • Color can fade over time leaving it more visible to the fish you are trying to catch.

Trout Fishing Line Buyers Guide


Weight is incredibly important when fishing for trout. For those that may not understand the line’s weight is what impacts how easy or difficult it may be to catch certain fish. The heavier a line weighs the easier it is to catch bigger fish.

However, trout don’t grow to be big fishes and for specific Trout fishing it isn’t necessary to have a heavier weighing line as you will just make it much more difficult for yourself.

Ideally you want your line to weigh around 4 to 6 lbs as this is the most useful for catching fish that are the size of Trout, it is important to research this properly before making your final decision, as it would only make it more difficult on yourself if you used a line that was meant to be used for much bigger fish.


Strength is another imperative factor to consider when Trout fishing. Although a light line is what you want for Trout fishing it is important that it isn’t so light that the pull of a trout can break it.

Strength is definitely an important factor when it comes to Trout fishing and should be treated as such when making your decision. A line can never be too strong, but that being said if you focus too much on the strength of the line you may be missing out on more important features like sensitivity for example.

It is highly recommended that you properly look into how strong you want your line to be before making your final decision as you have to remember that Trout aren’t the kings of the ocean and are actually quite small requiring quite little strength.


When it comes to catching Trout visibility is highly important. Often you find Trouts in lakes or slow moving rivers, because of this Trouts aren’t very aggressive or territorial when found in these environments.

Trouts can be very hesitant when it’s time to take a bite out of your bait so it is important to select a line that maintains its invisibility over time, the best type of line to do this is a fluorocarbon line.

If a Trout is made aware of your line they are much less likely to take a stab at that bait that sits on it. It’s good to look at different colors that are offered when making your decision as this will also impact how visible the line that you are using is.

Luckily the above stated products have many options to choose from when it comes to making your final decision about which line is best for catching trout.

Line Memory

Line memory is an important part of fishing in general and is not specific to just catching Trout. Line memory is when a line starts to curl because it has been sat on the spool for an elongated time which of course just happens anyway when fishing because you most likely won’t use all your line up in one trip.

When a line starts to curl it can make the whole casting process an incredibly difficult one and will also tangle a lot more frequently than you might expect. Therefore it is important to make sure you look for a line that offers low memory when it comes to making your decision.

Luckily lots of the above stated off a low memory line which is by far something you should consider purchasing if Trout fishing is your forte.


Stretch is highly important when it comes to Trout fishing, if a line has a lot of stretch it means that it’s much less sensitive than a line that offers zero stretch, with regards to Trout fishing it is important to have zero stretch because like previously mentioned Trout are much more passive than many other types of fish and won’t jump at your bait right away, meaning you need all the time possible to have the best chance at catching one.

Fluorocarbon lines usually offer the least amount of stretch as they are normally the most sensitive, the two kind of come as a package deal. The stretch is what makes it so sensitive or very insensitive but as mentioned you will need the most sensitive line you can get your hands on when it comes to Trout fishing as they are always the most reactive when it comes to the smallest of nibbles that other lines may not feel.


Whether or not a line is easy to cast is again of importance, if a line is clunky and presents difficulties during the casting process then it could make the water much more lively meaning that Trout won’t even come anywhere near your bait and can render your whole trip pointless.

It is important to research properly before making your final decision about which type of line offers the easier casting process, especially if you are a beginner, more experienced fishermen may be able to get away with using a more difficult line to cast. But why make it more difficult on yourself if you are just starting out?

Luckily the above stated products all offer a very easy casting process that you will most definitely find incredibly useful if you are just starting out as a fisherman.

Frequently Asked Questions

How important is a sensitive line when it comes to catching Trout?

A highly sensitive line is of high importance in terms of catching trout. Like mentioned above they are passive fish and will often not jump at your bait so you want a line that will feel any little bump or nibble that a Trout may pose to it.

Zero stretch is also of high importance with regards to how sensitive a line is and quite frankly is the only important factor for a line’s sensitivity. So it does matter how sensitive your line is with regards to catching Trout.

Is a Strong line required?

Yes and no really, Trout don’t grow to be the biggest fish so therefore aren’t the strongest either. But you will need a line that is of decent strength as a line that is too weak can snap at the first sign of a pull.

Is it important to have a line of low visibility?

Yes, due to the nature of how you catch Trout, you want your line to be pretty transparent so as to give them the least amount of chance at spotting your line. High visibility won’t work great.
