As an angler, you surely know that not all fish are the same. Some are calmer and easier to catch, some are feisty, and some are easily spooked. Trout fall into the last category — one wrong move and your beautiful catch is gone. It’s easy to have a trout slip the hook.

Don’t waste your precious time on dull research. Instead, keep reading our complete buyer’s guide to the best fishing lines for trout!

How to pick the best line for fishing trout?

The fishing line market is surprisingly massive. If you used to simply go to the store and pick up whatever first caught your eye, you may be unaware that there are better and worse options. A line is a line, many anglers might say, but that’s not always necessarily true. 

The truth is that there are several things that set one line apart from another. The downside? Most lovers of fishing still won’t be able to tell them apart. It’s not exactly very straightforward, and without knowing the lingo, you may be at a loss on what to pick.

This is why we prepared this buying guide for you. Before you browse our selection of the best fishing lines for trout, make sure you check the parameters you need to keep in mind first.

Size & Weight

The terms “size” and “weight” can be confusing to new fishermen. Before we dive in deeper, let’s explain those terms in greater detail.

  • Size stands for the diameter of the fishing line measured in millimeters. The diameter plays a part in the stretch, depth, visibility, and casting ability of your line. The thinner the line, the better — fish won’t be able to spot it.
  • Weight affects the durability of a fishing line. A light line is not very durable, but it is great in other regards. A heavy line will be best for durability.

Fishing lines are made from many different materials, and the majority of them can be used for trout. We will stick to covering the four most common materials.

  • Fluorocarbon — Fluorocarbon is typically durable and rather smooth. It remains intact and maintains its integrity even if it scrapes across the seafloor. This is due to the fact that it’s very resistant to abrasion.
  • Monofilament — This is the second most popular type of fishing line for trout. Monofilament lines are quite affordable and they usually come in a wide array of colors. The downside? They are quite high memory and they tend to bend seemingly out of nowhere.
  • Lead core — These fishing lines are not often used by anglers in search of trout. Lead core fishing lines are ideal for fishing in deep lakes or open seas and oceans. This doesn’t really add up with a trout’s usual habitat.
  • Braided — These fishing lines are super popular and a common pick. They’re quite pricey, but for the extra few bucks, you get a very strong line, suited for spinning reels. They don’t kink or curl up as much as other lines do. The reason for that lies in them being low memory.

What is the best line weight for trout fishing?

It’s good to put these things into numbers when you shop. New anglers should most commonly aim on line weights between 4 and 6. If you’ve had a bit more experience fishing, you can go with anything in the 1.75 lb and 8.5 lb bracket. However, if you’re looking to catch steelhead, you need a line weight of 13.5 lb to 15.5 lb.


Sensitivity refers to how much you can feel your line when you cast it. Sensitive lines are far superior because they allow you to feel every motion of the fish. This, in turn, will improve your catch rate.


Much like sensitivity, the more durability, the better. Thick lines are great because they do not snap easily. On the other hand, a thin line is harder to spot by the fish.


Fishing line memory refers to how much a line retains its shape when its wound in the reel. The more you use a line, the more it will bend and those tiny little bends will stay, affecting your fishing experience. Low memory is fine for fishing in shallow lakes, rivers, or streams. You don’t need to cast far in those areas. However, on a sea or a deep lake, memory plays a big part.


The color of a fishing line is a tricky thing. On the one hand, brightly visible, neon colors are great for one simple reason: they are easy for YOU to spot. The downside is straightforward: the fish can spot them easily, too.

Most anglers opt for low-visibility fishing lines, however, that doesn’t mean you can’t go for neons. It’s all about what you personally prefer to do.

A brand called “Trout Magnet” can only mean good things for an angler in search of trout. While there are many things that don’t live up to their name, this fishing line most certainly does. Specially made for fishing for trout, Trout Magnet’s line is the key to capturing that elusive fish.

This is a fluorocarbon line that comes in two variants: a 2 lb and a 3 lb. That’s the ideal weight when fishing for trout. However, if it’s rainbow trout you’re after, you’ll want to pick up a line with a higher weight.

Have you ever fished with a hybrid fishing line? If you haven’t, it just might be the right time to start. RUNCL presents a fantastic model of a hybrid line that mixes fluorocarbon outer coating with a copolymer core. What makes that better than the pure fluoro variant? Let’s get into the details.

Firstly, the fluorocarbon coating provides many benefits. From an increased shock resistance & knot strength to abrasion resistance to being virtually tangle-free — this fishing line has it all. It only gets better with the addition of copolymer. Copolymer turns this strong powerhouse into a flexible fishing line with low memory and high knot strength.

Thanks to the high-density construction, this fluorocarbon fishing line will sink faster, reducing the time it takes for it to submerge fully. This is good as a time-saver, but it’s also the best thing ever for your catch rates, especially when it comes to trout. After all, if the line is too quick for the fish to spot, they are more likely to become interested in it soon.

All of these features are topped off by the extra sensitivity and low stretch, both of which are perfect for fishing trout. At the same time, this line is flexible enough to suit most kinds of fish. Whether trout is your main focus or just one of them, we recommend trying out this medium-range model.

However, this fishing line is strong enough to withstand even the fish that won’t stay still. It’s shock-resistant and it’s suited for gamefish.

The spools are all long, with some being as long as 1275 yards of fishing line. This is why it’s perfect for offshore fishing — you can use it in the sea or in the ocean. Bigger lakes will do just fine, too.

This fishing line is transparent, which makes it much more difficult for the fish to spot. It still provides great clarity and ensures successful catches. This is the best fishing line to use regardless of the type of water you’re fishing in.
