Trimmer Line Features and Considerations

Here’s the list of features that must be taken into consideration when looking for a trimmer line.

Diameter or Thickness

The diameter is a very crucial feature. The ideal diameter of the tool depends on the job you’ll be doing. Light jobs such as clearing the façade of a residential home and back lawns need a trimmer line that has a small diameter. In this case, anything between 0.065” and 0.080” will be enough.

However, for medium and heavy jobs like clearing a big lawn that has thick weeds, you will need a line with a diameter of between 0.085” and 0.105”.

Big yards, industrial landscaping, and golf courses will need something with a diameter of more than 0.110-inch.

Material and Construction

These tools are made from various materials like polymer, plastic, nylon, as well as aluminum. The material chosen is reliant on the trimmer usage on various aspects and weed thickness.

Typically, a plastic or nylon material is utilized for basic and everyday trimming tasks for your garden areas and house lawns.

For hefty mowing, trimmer lines that are built from a combination of synthetic polymers, nylon, and aluminum are often used. Compared to plastic and nylon, these trimmer lines are stronger and more durable.

Shape and Style

Trimmer lines are available in different shapes or styles. Each of them has a big impact on the trimmer’s cutting ability. The following are the shapes/styles of trimmer lines.


This trimmer line is ideal for trimming the edges of the grass and removing weeds around residential areas. It won’t wear out easily, unlike other styles and it is pretty easy to replace in the trimmer.

The only drawback of this style is that it can’t handle thick weeds and big areas.

Multiple sided

Opposite to round styles, multi-sided trimmer lines can handle both thick weeds and large yards. As the name implies, this style has multiple sides that have the square, pentagon, and star, being the most popular shapes.

However, it tends to break easily especially when accidentally used in stones, fences, or curbs.


Since it has several sides, a square trimmer line is also ideal for cutting dense weeds. If you are planning to clear weeds or grass in areas that are full of trees and stones, then this is for you. Either way, this tool is not suitable for light trimming jobs.


Because it doesn’t easily break when hit on concrete and trees, a twisted trimmer line is known as the strongest tool for professional cutting uses. The twisting will improve efficiency and offer additional strength while decreasing the noise levels as well.


Serrated trimmer lines have edges that act and look like teeth. This style is capable of cutting through tall grasses and thick leaves while leaving neat and clean trims. Lastly, its trimming power makes it ideal for medium to heavy trimming works.


Replacing the trimmer line persistently is actually a time-consuming and irritating task. Being that said, it is recommended that you opt for a line that is built with durability in mind.

By simply considering the material used, and reading some customer reviews before making a purchase, you will be able to find out how durable a certain product is.


The correct size will depend on what you’re utilizing your trimmer for. For instance, if you’re trying to trim over thick brush, investing in stronger lines is necessary. They will not break while doing the job.

Make sure the size of the trimmer line will perfectly fit into your trimmer. Additionally, consider the spool’s size.

However, if you are doing lots of landscaping tasks, a bigger spool tends to last longer and expected to be more cost-efficient.

Line Length

When you are looking for a trimmer line in the market you will notice that this product comes in rolls or spools. Having that said, it is very important that you keep an eye on how many yards or feet of trimmer line you’re obtaining for your money.

Bear in mind that you won’t need as much as of durable lines since it won’t have to be changed regularly. Without a doubt, a long length that is accessible in a cheap price tag is tempting, but sometimes the quality of the line is being sacrificed.


Heavy-duty trimmer lines are more expensive. They could be a money saver, if they last longer.

A trimmer line that is reinforced and thick will have to be changed far less often. That is actually good for your pocketbook and time.

There are lots of types and styles of trimmer lines currently available on the market. For you to make the wise and right decision, you will need a lot of useful information. The reviews along with the list of things that must be taken into consideration will help you in finding the line with ease.
