Best Trimmer Line Buying Guide

Now that you have gone through our reviews of the best trimmer line in the market, it’s time for you to learn about some of the crucial aspects. And these features of a trimmer will let you make an informed decision. 

Dimensions 

The dimensions of a string trimmer line refer to its length and diameter. Trimmer lines come in a variety of shapes and sizes. Typically, trimmer lines have a length that ranges from 105 feet up to 1134 feet. 

On the other hand, the diameter of the trimmer line ranges from .065 inches up to .105 inches. 

You should purchase a trimmer line that at least has a diameter of .065 inches. Otherwise, the line would be too thin to cut the grass and weeds properly. 

And the ideal length for a trimmer line is 800 feet. 

Type of the line

String trimmer lines are categorized according to their shapes and designs. There are four types of line spools available in the market, and those categories are described below:

Rounded:

Rounded trimmer lines are quite common, and most of the trimmer lines in the market have this design. The best part about this type of trimmer line is that they don’t get damaged easily, and that’s why they last for a long time. 

Five-point trimmer line:

This type of trimmer line has a pentagonal shape, and they are best suited for taking care of tough grass and weeds. 

Twisted:

As the name suggests, this type of trimmer line has a twisted design. These lines are used by landscape professionals as they are perfect for cutting tall, thick grass. 

Square:

Although square lines are thicker than other types of lines, they wear down quickly, and they are less durable than the other types of string trimmer lines. 

Compatibility 

While purchasing a string trimmer line, you have to check whether the trimmer line is compatible with your string trimmer or not. Only buy the trimmer line if the model number of your string trimmer is included in the product description of the line. 

Final Verdict

Let’s face it; you would not have cared about the trimmer line of your string trimmer unless it was damaged. And when a trimmer line malfunctions, it’s an extremely frustrating experience for the user.
