Most fishing line falls into three families: monofilament, fluorocarbon and braid. This guide compares them using the New York State DEC’s intermediate fishing guide, Oregon ODFW’s starter outfits and Minnesota DNR’s MinnAqua lessons, and covers pound ratings, knots, line twist and disposal.
What Are the Three Main Fishing Line Types?
Walk into any tackle shop and you will see spools of monofilament, fluorocarbon and braided line. According to the New York State DEC’s intermediate fishing guide, monofilament (often called mono) is essentially a long strand of nylon. Fluorocarbon line is nearly invisible in water, and braided line is created by weaving nylon or other man-made fibers into a single strand. Each type behaves differently when you cast, when a fish bites and when you tie a knot. Understanding those differences helps you match the line to the fish you are after and the water you are fishing.
Line strength is described in pound rating. The Minnesota DNR MinnAqua program explains that the higher the pound rating, the heavier or stronger the line. A 4-pound line, for example, will not break unless there is four pounds or more of pull on it. Choosing the right pound rating depends on the size and strength of your target fish. A sunfish calls for light line, while northern pike or muskellunge demand 12-pound line or higher.
Monofilament Line: The All-Around Starter
Monofilament is still the most popular line used by anglers, according to the New York DEC. It is inexpensive, works well for most fishing situations and is easy to tie knots with. The Oregon Department of Fish and Wildlife recommends 6-12 pound monofilament for an all-purpose trout, bass and panfish outfit, and 2-6 pound mono for a light trout and panfish setup.
Mono has two important traits that shape how it fishes. First, it stretches. The New York DEC lists stretch as a characteristic of mono. Second, mono absorbs water and has memory, meaning it stays in the shape it was stored in. If pre-spooled line has been on a reel for a while, the DEC notes that it will curl easily and create tangles. For that reason, the DEC suggests putting fresh line on a reel that comes pre-spooled.
Fluorocarbon Line: Low Visibility and Low Stretch
Fluorocarbon’s standout feature is that it is nearly invisible in water, as the New York DEC describes. This makes it a popular choice for easily spooked fish or very clear water. The DEC also notes that fluorocarbon is often used as a leader when fly fishing. It has low stretch, good knot strength and does not absorb water, but it sinks rather than floats.
The trade-offs are cost and handling. Fluorocarbon is expensive and has strong memory, the DEC states, meaning it coils and forms loops that tangle easily. It also does not biodegrade, so responsible disposal is important. You can learn more about leader setups in our Fishing Leader Guide.
Braided Line: Strength and Sensitivity Without Stretch
Braided line is very strong and has a smaller diameter than monofilament of the same pound rating, according to the New York DEC. It has low stretch, which means you feel every tap and bump transmitted directly through the line. The Oregon Department of Fish and Wildlife lists 15-30 pound braided line for an all-purpose salmon outfit and 25-40 pound braid for sturgeon, reflecting the strength advantage braid offers for large, powerful fish.
Braided line comes with several trade-offs. The DEC points out that it is expensive, difficult to untangle, does not biodegrade and is easily seen by fish. It can also cut into cheap line guides and your hands. Knots matter with braid: the DEC warns that braided line may break easily if you use a clinch knot, and recommends a Palomar knot or a knot suggested by the manufacturer. Our Fishing Knots Guide walks through which knots work best for each line type.
Line Type Comparison at a Glance
The table below is built from the advantages and disadvantages listed by the New York State DEC’s intermediate fishing guide. Use it as a quick reference when you are deciding which line to spool.
| Line Type | Key Traits | Common Uses |
|---|---|---|
| Monofilament (Mono) | Inexpensive, stretches, absorbs water, easy to tie knots | All-purpose freshwater fishing; good starter line for trout, bass and panfish |
| Fluorocarbon | Nearly invisible in water, low stretch, sinks, strong memory, expensive | Clear water, spooky fish, leader material for fly fishing and other rigs |
| Braided Line | Very strong, small diameter, low stretch, expensive, easily seen by fish | ODFW lists braid for its all-purpose salmon and sturgeon outfits |
Matching Line to Rod, Reel and Target Fish
The New York DEC advises that matching the right rod with the right reel and line allows you to fish more effectively. A medium action 6- to 6.5-foot spinning rod matched with a reel that holds 80 to 150 yards of 8-pound monofilament is a good all-around starter setup. The Oregon Department of Fish and Wildlife offers similar starting points: a 5.5-foot medium action rod with 6-12 pound mono for trout, bass and panfish, or a 6.5-foot medium action rod with 6-15 pound mono for larger bass.
The Minnesota DNR MinnAqua program ties line choice directly to the fish species. Sunfish, yellow perch and crappies call for 4-pound line. Walleye and smallmouth bass move up to 6-pound line. Largemouth bass and catfish require 10-pound line or higher. Northern pike need 12-pound line or higher, and muskellunge demand 20-pound line or higher. The size of the fish determines the line size, and mouth size helps determine the size of the lure or bait. For a deeper look at pairing your gear, see How to Match a Rod, Reel and Line.
Knots That Hold: Why Line Type Changes the Knot You Tie
The Minnesota DNR teaches that a fishing line is only as strong as the knot. The improved clinch knot is one of the most versatile and suits most fishing styles, but the New York DEC specifically cautions against using a clinch knot with braided line. Braid may break easily with a clinch knot. Instead, the DEC recommends the Palomar knot for braid, describing it as stronger than the improved clinch knot and a good choice when using braided lines. The blood knot is another useful knot for tying two lines together, and the DEC notes it is very popular with fly fishermen. Our Fishing Knots Guide covers these and other knots in detail.
Line Care, Twist Prevention and Safe Handling
Line twist is the biggest problem with spinning reels, according to the New York DEC. Tangles form when line has been incorrectly put on the reel or when reeling in loose line. To prevent tangles, always tighten your line on the spool before reeling in by either manually closing the bail or beginning to reel just before the lure hits the water. If you see a loop in your line, do not try to cast it out. The DEC says to open the bail and strip line off the reel until you pull the loop out, then close the bail and reel in while keeping the line tight.
Additional tips from the DEC include putting line on the reel correctly by following the instructions on the line packaging, flipping the bail over by hand after a cast and giving the line a slight tug before reeling, and leaving about 1/8 inch of space from the edge of the reel’s spool.

Safety around fishing line matters. The Minnesota DNR warns against biting fishing line with your teeth, as it can chip teeth or cause someone to swallow a loose piece of line. Use nippers or nail clippers to cut line. Similarly, never bite sinkers to secure them; they are easily swallowed and made of hard metal that can chip teeth. Use needlenosed pliers to open and secure sinkers. Most sinkers are still made of lead, which can be toxic if ingested.
Keeping Line Out of the Water and Disposing of It Properly
Discarded fishing line poses a serious hazard to wildlife. The Minnesota DNR states that line left in the water or on the ground can entangle and endanger animals such as birds. The New York DEC lists “doesn’t biodegrade” among the drawbacks of both fluorocarbon and braided line. Many bait shops accept used monofilament line for recycling, according to the Minnesota DNR. Always pack out any cut line and dispose of it in a recycling bin or a sealed trash container. For more on keeping your gear organized and secure, visit Tackle Box vs Tackle Bag vs Fishing Backpack.
Frequently asked questions
Can I use the same line for all types of fishing?
No single line type excels in every situation. The New York DEC explains that monofilament works well for most fishing situations and is easy to tie, but it stretches and absorbs water. Fluorocarbon is nearly invisible in water, making it better for clear water and spooky fish, but it is expensive and has strong memory. Braided line is very strong with low stretch, but it is easily seen by fish and requires special knots. The Minnesota DNR MinnAqua program emphasizes that the size of the fish determines the line size, and habitat and food preferences help determine which type of lure or bait to use.
What pound rating line should a beginner start with?
The New York DEC suggests a medium action 6- to 6.5-foot spinning rod matched with a reel that holds 80 to 150 yards of 8-pound monofilament as a good all-around starter outfit. The Oregon Department of Fish and Wildlife recommends 6-12 pound monofilament for an all-purpose trout, bass and panfish setup. The Minnesota DNR advises that lighter lines like 4-pound line are appropriate for sunfish, trout and perch, while heavier lines of 12-pound line or higher are needed for northern pike and muskellunge. Start with a versatile medium setup and adjust based on the fish you target most often.
Do I need a leader with braided line?
Braided line is easily seen by fish, as the New York DEC points out. The DEC also mentions monofilament or fluorocarbon leaders on Dacron line used for tip-up ice fishing, and notes fluorocarbon is often used as a leader in fly fishing. The Minnesota DNR notes that leaders are six- to twelve-inch lengths of line that often contain metal cores, and are tied to the end of the line when fishing for large fish with sharp teeth such as walleye, northern pike and muskellunge. Whether you add one to braid is a choice the guides leave to you; follow the line maker’s knot advice for the connection. For more on leader materials and lengths, see our Fishing Leader Guide.
Fishing rules, including license requirements, legal gear, size limits and bag limits, vary by state and by individual water body. Always check the regulations published by your state wildlife agency before heading out.
