Every angler knows that their fishing line is the most important part of their tackle. After all, it’s the only thing connecting you to the fish! But what many anglers don’t know is that even fishing lines can eventually go bad.

So, how long does the fishing line last? Let’s explore this question and learn how to extend the life of your fishing line.

Average Fishing Line Lifespan

The average lifespan of a fishing line depends on a few factors, such as its type and use, but generally speaking, most monofilament lines should be replaced every 3-4 years. This is due to the fact that monofilament lines will slowly degrade over time due to exposure to UV light and water.

It’s also important to note that certain types of monofilament lines are more prone to breaking than others; for instance, fluorocarbon lines tend to have a shorter lifespan than nylon or copolymer lines.

If you’re a frequent angler who fishes in saltwater or heavily polluted waters, it’s important to replace your fishing line more often than every 3-4 years.

This is because these types of waters are very damaging to fishing lines and can cause them to break down much faster than normal. In these cases, replace your line annually or even more frequently if necessary.

Another factor that affects the lifespan of your fishing line is how you store it when not in use. Keeping your reel stored in a cool, dry place will help protect it from damage caused by UV light and humidity — two common culprits for degraded fishing lines.

Additionally, taking care when casting and reeling in ensures that no kinks or loops form in the line which could lead to breaks during retrieval.


Fishing lines play an integral role in an angler’s success so it’s important for them to pay attention to how long their particular type of line lasts before needing replacement.

On average, most types of monofilament should be replaced every 3-4 years but this can vary depending on usage and storage conditions.

By taking good care of your reel and regularly replacing your old line with fresh new ones when necessary, you’ll ensure that you always have reliable tackle when out on the water!
