What is a Trimmer Line?

We have already mentioned what a string trimmer, or a weed eater, is. It is a useful tool that would enable you to reach the farthest corner of your yard with maximum ease.

What you may not know is that instead of a blade, the trimmer uses a string trimmer line for cutting the weeds or the grass. The string, known as the trimmer line, is the most vital part of the entire tool and has to be inserted inside the weed whacker.

A .155-inch trimmer line is most ideal for loads of trimming work in large areas with heavy weed and thicker grass.

Although new weed eaters come with their own trimmer lines, they will eventually need replacement. For this reason, we have done extensive research on .155-inch trimmer lines so that you can have an easy time getting the best line for your trimmer.

The Buying Guide

If you have ever thought that all trimmer lines are the same, then you are not alone. They may appear similar, but in truth, there are different trimmer lines out there.

In this section, we are going to guide you on how you can use these differences to narrow down your search and ensure you end up with the best item for the job.


This is an essential feature as it determines how long the trimmer line would serve you. If you plan to use the line for light duties, the best materials are nylon and plastic.

As for the heavy-duty lines, aluminum, nylon, and synthetic polymers would ensure that the line is sturdy enough to last for a lifetime.


You may also not have known that trimmer lines are available in different shapes, and this determines their cutting efficiency.

It is necessary for you to pick the right shape as it determines the sound, vibration, and power of the equipment. Nevertheless, the shape will depend mostly on the kind of weed eater you have.

The most common trimmer line shapes in the market include twisted, bladed, rounded, square, and spiral shape.

Let’s briefly check out the common shapes:

  1. The round trimmer line is perfect for light duties around your backyard.
  2. Multi sided trimmer line, which is ideal for medium-sized jobs.
  3. The twisted and serrated trimmer line is perfect for large areas with thick weeds and grass.


This is a vital aspect that you should never take for granted since it affects the ease with which the string trimmer line would cut through thick weeds.

The light-duty lines’ diameters range between 0.065-0.080, while the medium-duty typically lies between 0.085-0.105.

For the heavy-duty lines, their diameters usually lie between 0.110 going up, and this is where our line of interest (.155-inch) lies.

How to Find the Correct Trimmer Line Diameter

We feel it is important for you to know how to pick the correct line diameter.

The first thing you need to do is check your trimmer’s diameter to find out if it can accommodate your trimmer line of choice. Note that your trimmer may not be capable of handling a .155 diameter trimmer line especially if it is a low-end option.

Keep in mind that a commercial grade trimmer line designed for larger yards and industrial landscaping can easily accommodate a .155 trimmer line.


When we talk about power, we are referring to your trimmer’s ability to be universal. Prior to purchasing a trimmer line, you want to confirm if it is gas, electric, or battery operated.

Since there is an array of trimming lines in the market, one of the main factors you need to consider is whether the line you pick is compatible with your trimmer.

Still, you want to know the trimmer you are using in terms of what it runs on to determine which line would be best.

Bonus Features

It is also important to factor in some extra features. For instance, if you are in a neighborhood with noise restrictions, then you should look out for a low-noise or low-vibration line.

You would not want to be a nuisance to your neighbors or worse still, get into trouble with the law. Aside from that, you want to ensure that the line you pick can withstand harsh weather conditions. The last thing you want is for the line to fall apart because of things like snow.

Benefits of a .155 Trimmer Line

.155 trimmer lines are suitable for tough weeds and grass. We are talking about thick stalks and long greenery here.

This size of trimmer line is best for not just for your large yard, but commercial work including trimming golf courses and doing industrial landscaping.

A trimmer line works just as blades would only that it is more thorough.

Frequently Asked Questions (FAQs)

In this section, we shall attempt to answer some of the questions we faced during our research on trimmer lines.

A: The market comprises several great products when it comes to commercial trimmer lines so it is not easy to single out one as the best. That said; brands like Cyclone do stand out.

Another way to look at it is this way. In our opinion, a good commercial line would be a twisted one with a .155 diameter.

Now, the size alone is not enough to determine the quality of line and it is not the only factor that makes it ideal for commercial use.

A twisted trimmer line is ideal for heavy-duty use and is therefore best for thicker greenery and larger areas.
