Weed Eater String Thickness for Different Duties

If you have been using a string trimmer line it probably doesn’t surprise you to learn that thicker lines are used for tougher applications. This is a general rule and it is because a larger diameter increases the durability and efficiency of the line.

This then leads to less wear-out and breakage.

Here is how you should use different string thicknesses:

Light-Duty Trimming

For light-duty trimming such as grass, a 0.065″ – 0.080″ trimmer line should suffice. It’s just thin enough yet tough and efficient for such tasks.

Medium-Duty Trimming

For medium-duty, such as thicker grass and a few weeds, a 0.085″– 0.105″ trimmer line should be sufficient. Remember, the thicker the line gets, the more wind resistance it faces and the more power it requires.

Heavy-Duty Trimming/Tasks

For thick weeds and grass, a 0.110″ – 0.130″ trimmer line will work best. Think of thick brush and coarse weeds that would be deemed enough to overwhelm any residential-grade line.

Extra Heavy-Duty Trimming

If you are dealing with heavier and tougher vegetation, then you will need a 0.130+” trimmer line. Durability is certainly a factor here. Normally, lines that fall in this category are square in shape of maximize effectiveness while minimizing operational noise.

Buying Guide

To ensure that you are getting the strongest weed eater string, you have to consider some factors before purchasing. These include:


Trimmer strings come in serrated, twisted, multi-sided, square, and round shapes. Now, this is important because the shape influences the performance of the string in a number of ways including noise level. Durability, and cleanness of the cut.

For instance, round strings are easy to reload, durable, and economical making them ideal for yards with a few weeds and more grass while multi-sided strings are perfect for yards with thick weeds and grass.

You, therefore, want to purchase based on the thickness of the bushes and grass you want to cut.


Continuous use with hard surfaces, heavy weeds, and brushes is where you will notice a difference in durability when it comes to trimmer lines. With a durable string, you will be able to trim more per spool.

Now, the longevity of a trimmer line depends on its shape, material, and of course, what you will be trimming. Given the same material and shape, you want to keep in mind that the thicker it is, the slower it will wear down.

If you are looking for the ultimate durability, then go for a round string. This is because it combines more material, it offers longevity. Round string typically features a non-nylon polymer and reinforced nylon build and this offers greater durability compared to basic nylon.


The standard trimmer line is made of tough monofilament nylon and that is because this material has been used as the industry standard for years. However, manufacturers are constantly making improvements to increase capability and durability.

While nylon is effective on its own, you want to keep in mind that there are stronger materials in the market.

Materials like composite nylon come with breakage resistance and more cutting power so you may want to consider such.

Line Size

All string trimmers whether gas-powered, plug-in electric, or cordless come with line size limitations. The diameter of a line has a lot to do with how long it lasts.

You, therefore, want to consider your cutting conditions like how much you want to spend and how much you would want to reload when choosing your line’s thickness.

It is not a guarantee that the line you choose will fit the trimmer you have so ensure that you confirm that from the manufacturer’s instructions before buying a line for your trimmer.
