How to Choose the Right Trimmer Line

Before you make a trimmer line purchase you should start by checking the manual for your weed eater. Some models can only use a certain width of line or it will cause a lot of problems. The manual will provide the information on what size refill will work the best with that model.

Once you know what size you need the next step is to take a walk around the area you will be cutting regularly and see what kind of materials you will be cutting. The typical rule of thumb is that larger line will cut anything below its own size. If you don’t have anything other than grasses and light weeds to cut, spending money on a heavy duty, professional style trimmer line is just a waste of your money. Noise pollution is something else to consider if you are weed eating in a residential area. If you live in a place where there are noise ordinances consider buying the type of trimmer line that is designed to be quieter such as the x-shaped line. It will be a little more expensive but you won’t have to worry so much about noise.

  • Material – There are several different materials that trimmer line is made from. Light duty line is usually made of plastic and nylon. The heavier-duty lines are made from a combination of materials including synthetic polymers, nylon, and aluminum. The additional materials added to the line provide more strength and durability.
  • Durability – If your trimmer line breaks down fast you will need to replace it more often. There are some trimmer lines available that are much more durable and will not require you to have to replace the spool so frequently. Look at the list of line shapes above and match the shape with the type of cutting jobs you will have and you’ll be able to purchase trimmer line that will last. If you have a lot of dense weeds and grasses or you have your own professional lawn service, it is wise to spend the money on the best quality, strongest trimmer line you can purchase. You do not want to have to stop in the middle of a paid job to change out the string or fix jammed lines from using a trimmer line that is not up to the heavier jobs.
  • Diameter – Diameter of the line is one of the most important factors to consider. The diameter of the trimmer line determines how well it will cut through certain weeds and grasses. The different diameter stages are as follows:
    1. Light diameter – .065” to .080”
    2. Medium diameter – .085” to .105”
    3. Large diameter- .110” and above
  • Customer comments and reviews – One of the best ways to gain some inside information on the different trimmer lines that you are considering is to read customer comments from people who have purchased the trimmer lines you are interested in and are using them. You’ll be able to find out information about longevity, performance, ease of installation, durability and much more. This inside information can help you eliminate trimmer lines that are not performing properly. You don’t want to choose line that is weak and that breaks a lot.

  • Brand name – As with every product on the market, brand name means something. This doesn’t mean that there are not decent no-name trimmer lines on the market but in general you get what you pay for. Buying brand name trimmer line doesn’t 100% guarantee excellent products but more often than not, it does and the company typically stands behind their products with good warranties as well. When looking at the brand name trimmer line, make sure that it ticks off all the boxes and that you are careful to choose the line that works for your specific cutting needs.
  • Ease of installation – No one wants to struggle with a complicated weed eater, trying to install a new trimmer line. Some types of trimmer line install easily and others are much more complicated and involve hand winding the line around the spool. Look for trimmer line that is already spooled if possible or brands that advertise they are easy to install. That will prevent frustration and hassle when it comes to replacing the existing spool once it runs out.
