How Many Pounds Can a 20 Pound Fishing Line Hold?

The answer to the question “How many pounds can a 20 pound fishing line hold?” depends on several factors including the type of line, its diameter, and the type of knot used to tie it. A quality monofilament fishing line like Berkley Trilene Big Game can hold up to 20 pounds of pull on a 4-pound test line. But, if you’re using a braided line like Power Pro, you can expect to get up to 30 pounds on a 20-pound test line. That’s because braided lines are more abrasion-resistant and have greater strength than mono lines.

The diameter of the fishing line also affects its strength.

A smaller diameter fishing line is stronger than one with a larger diameter. The thicker the line, the more it will stretch when tension is applied. This means that you’ll need to use a stronger test weight for thicker lines in order to get an accurate indication of its breaking strength.

Finally, the type of knot used to tie the fishing line has an impact on its breaking strength as well. For example, if you’re using an improved clinch knot or Palomar knot, you’ll get more holding power than if you use an overhand knot or uni-knot. To get the most out of your fishing line and ensure that it holds up under pressure, make sure that you use proper knots for tying your line.


In conclusion, how many pounds a 20 pound fishing line can hold depends on several factors such as type of line, diameter and type of knot used. Mono lines can typically hold up to 20 pounds while braided lines can generally hold up to 30 pounds on a 20-pound test weight. The thinner and smaller diameter lines are typically stronger while proper knots should be used secure the strongest possible connection.
