How Do You Calculate Fishing Line?

Fishing line is the most important piece of equipment for any angler. It is the connection between you and the fish, and it is essential to have a reliable line that will work in any situation. But how do you calculate fishing line strength?

The first step in calculating your fishing line strength is to determine what type of fishing you are doing. Different types of fishing require different types of lines, and each type has its own rating system.

For example, freshwater anglers typically use monofilament line, while saltwater anglers often use braided lines. Once you know what type of line you need, then you can start looking at the ratings.

Each type of fishing line has a designated breaking strength rating, which is measured in pounds or kilograms. This rating indicates how much weight a line can handle before it breaks or snaps.

The higher the number, the stronger the line will be. It’s important to select a line with a breaking strength that’s appropriate for your Target species and conditions.

In addition to breaking strength ratings, there are also other factors to consider when choosing a fishing line. This includes factors such as diameter (thickness), visibility (how visible it is underwater), abrasion resistance (how well it holds up against sharp objects like rocks), and stretch (the amount of give or elasticity). All these characteristics can affect how well your chosen line performs when out on the water.


Calculating fishing line strength requires careful research based on the type of fishing you’re doing and the species of fish that you’re Targeting. Look at breaking strength ratings, diameter, visibility, abrasion resistance, and stretch when selecting a suitable fishing line for your needs. With proper care and attention to detail, you can ensure that your chosen fishing line will provide maximum performance out on the water.
