String Trimmer Line Buyer’s Guide

To pick the best string trimmer line, you have to start with familiarizing yourself with the basics about this product. This guide provides all of the knowledge necessary to make the best choice.

String Trim Line Size

The right line size depends on what you are using your string trimmer for. For example, if you are trying to cut through thick brush, a strong line is necessary so that it does not break during the job. The line size must also fit into your string trimmer.

You should also consider the size of the spool. If you do a lot of landscaping work, larger spools will last longer, and therefore, likely be more cost efficient.

String Trimmer Line Thickness

For tougher landscaping and trimming jobs, you need a thicker string line. As the line diameter increases, so does the line’s durability to reduce wear-out and breakage.

There are numerous thickness options. The following shows the average thickness for different types of jobs:

  • Trimming grass and other light work: 0.065 to 0.085 inches
  • Weeds, thick grass, and other moderate jobs: 0.085 to 0.110 inches
  • Thick underbrush and other heavy-duty jobs: 0.110 inches and above

If you are using a cordless string trimmer, the thicker the line, the more effect it will have on your runtime and power. If your trimmer operates at a low voltage, it may struggle to keep up with a very thick line. In these instances, sticking to the string size recommendations from the manufacturer will ensure the greatest efficiency.

String Trimmer Line Shape

The line shape has a direct effect on cutting efficiency. You can find a variety of line shapes, including:

  • Round: This is the most common line shape. It rips what you cut instead of leaving clean lines.
  • Twisted: This type has a cutting edge for greater precision.
  • Star or square: These shapes have a sharp cut.
  • Serrated: This type of line looks like a serrated kitchen knife. It has teeth. This shape is ideal for heavy-duty work because it saws through what you are cutting.

Consider what you are cutting and the level of precision necessary to pick the best shape for your trimmer line. This will improve overall efficiency and ensure that you can complete the job exactly to your specifications.

String Trimmer Line Material

The most common line material is standard nylon. It is best for light work since it has a tendency to break and wear out easily. For heavy-duty jobs, there is reinforced composite nylon that is considerably more durable. Other heavy-duty line materials include lines with aluminum additives and internally reinforced nylon.

Conclusion

With these five string trimmer line options, it is easy to find the one that will work for your needs. Just ensure that the specifications of the line meet the needs of your string trimmer so that you have a perfect fit.
