What is a Trimmer Line and Why dB003VPAEL Do You Need One?

A trimmer line is essentially a monofilament line used in string trimmers to slice through weeds, grass, and small, woody plants. The line spins at high speed to cut through dense vegetation and foliage. A trimmer line is fed into a string trimmer that is a must-have gardening tool to clear overgrown weeds and thick grasses in no time. String trimmers now come in gas-powered, electric, or cordless versions.

Now, I know what you’re wondering. Why should I buy a string trimmer when I have a lawnmower? Well, lawnmowers can’t reach difficult corners of your garden.

A string trimmer allows you to clean the tight corners of your garden making it more effective and efficient than a lawnmower. You can use a string trimmer to slice through tall weeds or clean the sidewalks in neat strokes. 

Thus, investing in a string trimmer is important for regular clean-ups and maintenance of your lawn.

Different Types of Trimmer Lines: What Type Should You Get?

Not all trimmer lines are born equal. They differ based on size, shape, and material. If you choose the wrong one, the string might break and you will have to reload. Reloading the wrong type of line is a struggle. Thus, it is very important to buy the right type of trimmer line for your string trimmer.

You should read the owner’s manual thoroughly before buying any trimmer line. It will inform you about the right string size and shape that fits your trimmer. You might also find this information on the maker’s website. Don’t skip this step because you don’t want to end up wasting money on a trimmer line that doesn’t fit.

To give you a better understanding of trimmer lines, the following are the different types of trimmer lines based on their shape, size, and material.

Size of Trimmer Line: What Size Should You Get?

The size of the trimmer line determines the cutting power of the machine. Larger the diameter, the more the cutting power. If you have thick grasses and weeds in your lawn, you should choose a trimmer line with a large diameter while a mid-range size will suffice for light work around the house.

The size of the line also depends on your string trimmer model. Every trimmer model has different specifications regarding the diameter of the line. Hence, you should read the guidelines carefully to check which diameter suits your trimmer.

There are 3 kinds of line sizes catering to different needs.

0.065″-0.085″ –  Trimmer lines that fall within this range are suited for light work.  If you want to remove light weed from your front or back lawn, this size will suit you. It is used for trimming grass and made for residential use.

0.085″ – 0.110″ –  Trimmer lines that fall within this mid-range are made for light commercial work and thicker grasses. If you have a bigger lawn or thick weeds, you should choose a line from this category.

Above 0.110″ – Trimmer lines above 0.110″ are for heavy-duty work. If you have thick underbrushes, this size will help in clearing them. It suits large yards, golf courses, and industrial landscaping.

People generally don’t use trimmer lines within this category for residential use. If you have light work, you don’t need to pay extra for this size.

Your perfect size depends on your need, the thickness of the grass, and ultimately on the instructions in the owner’s manual.

Shapes Of Trimmer Line:

The shape of the trimmer line determines its cutting efficiency, the noise produced while using the trimmer, and durability. The shape of the line decides how it will cut the grass. Hence, it’s a very important factor to consider before buying a trimmer line. The shape of the trimmer line depends majorly on the type of string trimmer you use therefore check the manual before finalizing any shape.

1. Round line

This is by far the most common trimmer line shape, particularly because it is suited for residential use. It easily trims light grass and weed. It is cheaper than others and lasts long if used for light work. The round trimmer line is easily replaceable, reloads quickly, and is be found compatible with most trimmers in the market.

A round line tends to rip the grass than slice through them as it doesn’t have a cutting edge. A round trimmer is not very effective against heavy weeds and foliage. Thus, a round trimmer line is suitable for those who have light work around the lawn.

2. Multi-sided line

Multi-sided lines cut cleanly through heavy weeds. If your lawn is overgrown with weeds and thick grasses, a Multi-sided line will serve you better. A 5-sided line tears smoothly through grass and weeds while a 6 bladed one can do the toughest of jobs making it suitable for professional use.

A multi-sided line might break on encountering hard surfaces hence it must be used carefully around obstacles. A multi-sided line can sometimes grip the vegetation a bit more tightly, which can pull the trimmer to the ground. You might have to exert extra pressure to use it.

The multi-sided line can be subdivided into categories like a square.

3. Square shaped line

A square-shaped trimmer line can cut through tall weeds in difficult terrains full of rocks and trees. The four sharp edges in a square-shaped trimmer line increase its cutting efficiency enabling it to slice through medium to heavy vegetation. If you have dense weed pile-up, a square trimmer will help you clear the place.

One problem you might face with these trimmer lines is that it can wrap around the grass which pulls the trimmer to the ground. You will have to exert pressure to pull the trimmer up from the ground.

Square shaped trimmer lines require a bit more maintenance as they have to be replaced properly to last long.

4. Twisted Trimmer line

If you live in an area with noise restrictions, here’s a trimmer line designed to reduce the noise produced while slicing through overgrown grass and weed. A twisted trimmer line is suitable for commercial use as it can clean large yards filled with heavy weeds and grass in smooth, neat cuts.

The strong build prevents it from breaking easily on contact with hard objects. Thus, you get a trimmer line that can do all the heavy weed whacking without producing much noise.

5. X-shaped

An X-shaped trimmer line resists overheating and is adaptable to both home and professional environments. If you want a trimmer line that does the work effectively without melting, an X-shaped trimmer line is ideal for you.

6. Serrated trimmer line

Serrated trimmer lines have sharp peaks or edges that resemble a kitchen knife or teeth. It cuts through the thickest of weeds and grass with ease. Serrated trimmer lines are fit for commercial use by professionals as it can clean large yards in relatively less time.

Heavy-duty tasks, overgrown lawns, and weed-filled yards can be cleared easily with this trimmer line.

Different Materials In Trimmer Lines:

The material of a trimmer line determines its longevity hence it becomes important to factor in the material before finalizing a string trimmer line.


Most standard trimmer lines are made of nylon as it is an economical option that finds favor with the masses. Manufacturers are reinforcing nylon with other materials to add extra strength. Often, aluminum is added to nylon to make it stronger. The polymer can also be used to reinforce nylon. Composite nylon materials can also be used to strengthen the line.


Titanium is used in trimmer lines for faster acceleration and increased cutting efficiency. It can slice through most things with ease. Titanium lines help in reducing fuel consumption as they finish the work in minimum time.

Titanium lines also cause less noise and are more durable than most trimmer lines. With so many benefits, it is natural that Titanium lines cost more than nylon ones.

For light, residential work a nylon line will suffice while Titanium lines are suited for professional use.

Things to Look for in a Good Trimmer Line: Buyers Guide

1. Welding Resistance

When a line overheats, it tends to melt and stick together. This is known as line welding. Welding occurs due to friction caused while the machine cuts through heavy weeds and grass.

If the string trimmer is used at high speeds near a fence, tar, or concrete walls, it softens from the heat and melts. You have to remove the string or get a new spool in such cases.

Thus, welding resistance is an important factor when buying a trimmer line. Lines made from Copolymer or Titanium have better resistance than Nylon.

2. Installation Method

Line installation method differs for different trimmer heads. You have to check your owner’s manual to find out which line installation method is compatible with your trimmer.

3. Pre-cut Trimmer Line

Pre-cut trimmer lines have already been cut to a particular size so that changing the line becomes a smooth and easy process. These are usually used in fixed head trimmers.

This installation method is quick but you are limited by the fixed length of the line.  If you misjudge the amount of line needed for the work, you will have to reload it frequently. If the line welds, you have to discard the line.

4. Spooled trimmer line

The spooled trimmer line is generally used by bump feed and twist feed systems. These trimmer lines are wound around the trimmer head and provide the whole length of the line for use. Thus, you don’t have to reload frequently.

Users can find reloading a bit difficult in this method but innovations in this area are making it easier to refill the line.

Durability Of Trimmer Lines:

The amount of work you can do with one spool determines its durability and it is affected by working around concrete walls, and hard objects.

Titanium and reinforced nylon lines are more durable than simple nylon lines.  Durability is impacted by the shape of the string and the nature of the work. Thicker lines are found to be more durable.

Shape, size, and material of the line

The shape, size, and material of the lines form the most important considerations. The needs fulfilled by each shape, size, and material are mentioned above. This will help you in choosing the right line for your gardening needs.


How much does a trimmer line cost?

The price of a trimmer line varies based on line size, shape, and material. The products mentioned here range from $10 to $30 to cater to every need and demographic.

What’s the point of a trimmer line?

A trimmer line is basically like a string that is fed into a trimmer to cut overgrown grass and weed. A trimmer can reach places the mower can’t hence it is an important tool in your garden maintenance kit. Be it the weedy border along the fence or the grass growing against the walls of the house, you can clear any place with a trimmer line.

If you have a particularly difficult terrain with rocks and tree roots, a trimmer will come in handy in clearing the weeds there. You can also maneuver it carefully against flower beds or sidewalks to clear the grass around it. Thus, a trimmer line achieves more efficiency in cutting grass and weeds than a mower.

Moreover, you can also add extra attachments to transform the trimmer into a sweeper or blower for different landscaping tasks.

Is a Thicker trimmer line better?

A thicker trimmer line is better for heavy-duty work like dense weed growth or thick grasses because an increased diameter leads to increased power. Thus, thicker lines are suitable for difficult tasks while thin ones suffice for light residential work. If you are a professional who wants to clear large yards of thick weeds, then thicker trimmer lines will be perfect.

It is important to remember that every model follows a specific size that must be adhered to. For eg, low voltage electric trimmer models are not very compatible with thick lines.

Is a twisted trimmer line better?

It all depends on your need and budget. If you live in a place with noise restrictions, a twisted line will serve better as it makes less noise and cuts clean through thick grasses and weeds. If you have light work, you don’t have to invest that much as a round line will suffice.

What trimmer line do professionals use?

Professionals generally prefer trimmer lines whose diameter is above 0.110″. Trimmer lines like Cyclone Desert Extrusion CY155S3 are a popular choice for landscaping professionals.

What is the best 0.095 trimmer line?
