Buyer’s guide – choose the best trimmer line for your need

Best Trimmer Lines - Buyer’s guide

Before buying any trimming line, there are things that you need to know. From the overview, you may think that all types of trimmer lines are the same in quality. The colors of the line and packaging of the trimmer may be different, but it looks like the products are almost the same in quality and features.

You have to know about the trimmer, trimmer quality, purpose of use of the trimmer, trimmer line, trimmer string, etc., which is essential to know for connecting it to the best weed-eating string. There are various characteristics of those trimmer lines, and all are different from each other.

Some important features like shape, durability reinforce material, length, and string thickness must be considered. These are given below.

Trimmer Line Shape

The shape of your timmer line definitely affects how well your devices work. Particularly you would see a variety of round, square, triangular, twisted and serrated trimmer lines. These various shapes would determine the type of jobs these shapes are appropriate for.

Multi-Sided Lines – This type of line includes the star, pentagon, triangle, and square-shaped ones. It is perfect for homeowners and it is very good for medium projects. It produces a cleaner cut than round lines and denser weed can be cut with this shape of the line. However, this type of line is the easiest to break, it can break easily when it comes in contact with pavements and curbs.

Round Line – This type of line is perfect for smaller bushes around the house.  The round line is almost the least powerful and durable trimmer line type.  If you just want to trim small grasses, this type of line is perfect for it. One of the best features of this type of line is the ability to replace it in your trimmer head. By the way, round lines are usually okay even when they hit sidewalks and pavements.

Serrated Lines – If you have thicker bushes, consider getting a serrated string trimmer line. These types of the line have edges that act as little teeth to help your device cut through weeds better. These types of lines can make a hard job much more manageable.

Twisted LinesA twisted line gives the device more cutting power. It also improves the efficiency of your trimmer line. These types of lines are stronger than the round lines and they produce less noise and vibration making it feel more comfortable to use. You also result in getting a clean and swift result when you use this type of trimmer line.

Trimmer Line Diameter

The diameter of a trimmer line determines the thickness of the size of the grass it can handle. There are three types of trimmer line diameter sizes. For smaller or light diameters, they measure around 0.65 – 0.08inches, unlike medium-sized diameters which measure about 0.085 – 0.105. If by chance, you require a bigger or larger heavy-duty trimmer line, you should consider going for the larger diameters which measure about 0.11 upwards. This diameter is really hard to find and it is very rare in the market.


When a trimmer line breaks down, users need to replace it before they can keep on using it. Doing this can come off as stress for both you and your wallet. Researching further and going through verified reviews is the best way you can guarantee not getting inferior products. The best trimmer line needs to be less often replaced. Also, note the speed because the light trimmer line can’t handle high speeds.

Line Length

When purchasing a trimmer line, you would find out it is packaged in spools. Be conversant about how many yards of trimmer line you can purchase with your money.  Keep in mind that you need less when it comes to heavy-duty trimmer line because it doesn’t need to be replaced that often.  Longer products at a cheaper rate also seem tempting but you would find out that you may use it quicker than a shorter quality line.


Trimmer lines also come in different types of materials and the type of material you choose will definitely affect how expensive, strong, and durable the product is.

Most homeowners use light-duty lines which are typically made out of nylon, plastics or both components.

For heavy-duty products, it is made out of synthetic polymers or aluminum. Most times in heavy-duty lines, most materials add strength as well as durability.

Trimmer Compatibility

Best Trimmer Lines - Buyer’s guide

Before purchasing a trimmer line, it is important that you cross-check your trimmer product and manual to get the correct size of the line your device can take. Many lines can fit almost all products be it electric or gas products. Some thicker trimmer products won’t work with most products, because it may not fit in easily into your trimmer head, therefore, keeping it from sticking out.

Trimmer products come either with a bump feed and twist head or a fixed head. A bump feed and twist head would work with a spool while a fixed head would require users to pre-cut pieces of the line.

What’s the point of a trimmer line?

Line trimmer is an electrical power tool that is used to cut the grass and weeds in every landscape area. These tools are essential for cutting down these things, and the trimmer line allows the machine to reach in every corner of the place whether it is large or small. Line trimmer and trimmer line play equally important roles in shaping the job. The long trimmer line is implanted with line trimmer so that it can cut all the weeds and grass easily. There is an amateur to professional trimmer line for use perfectly.

Which trimmer line is best for you?

All trimmer lines are not the same as mentioned before. Before going to buy a line trimmer and trimmer line, find which will be the best weed eater string and trimmer for you.  First, measure your place. If it is small, then go for a small to medium-duty trimmer line. If you need a large yard, then buy the heavy-duty and thick line. 


How to change a trimmer line?
To change a trimmer line, start out by dismantling the head of the string trimmer. You can refer to your operator’s handbook so you can know which type of trimmer line to use. Next, put in the line by cutting 10” part of the line and doubling it. When that is done, following the direction of the arrow found on top of the wheel, tightly wind the trimmer line around the spook and when it gets to 6 inches, push the ends to the hole marked 0.95”. When that is done, you can’t finesse the line onto the reel by maneuvering the line around the spool following the buttons. Next up, reposition the spring and lead the line. To avoid it from dropping, be careful to hold it down. After that, substitute the rod spring and locate the eyelets on top of the stem and pass the trimmer line through it. Now you are done, it is time to tighten the head. Set the reel to its original position on the barrel. Now eject the line, don’t squeeze tightly and tap the strings to ensure that the spaces between them are free. As soon as the line is in the right location, everything would be in order.
How long should the trimmer line be?
Just as we stated above, when changing a trimmer line, it is important to cut out about 10” before you wind it in a spool.
Why does my trimmer line keep breaking?
If your trimmer line keeps breaking and you are going through lots of lines, it may be as a result of using the wrong size of the line. Some people would go for a thicker line with the thought that it would cut thicker grasses but that is not the case. All these do is put load on the device making it move slower and get hotter. Also, your trimmer line can break when it hits curbs, pots or pavement because it keeps on slapping on hard strong surfaces instead of soft grass and this can degrade the line massively. This is why you should trim with the tip of the line although it still wears out, it does at a slow rate.
What size trimmer line is best?
The Trimmer line size should be dependent on the type of material you are using the device on. The Bigger the weed, the bigger the trimmer line you would use. For small short grasses that measure around 0.60 inches to 0.80 inches, it is ideal to use lines that measure from 0.60 inches to 0.80 inches. Medium-sized grasses that measure around 0.11 inches would need a trimmer line of 0.11 and for larger grasses and thicker stems, you can use lines that measure about 0.15 inches. This is a professional grade size and it is produced to last longer and handle tougher grasses.


So, you now have brief knowledge about the trimmer line. The trimmer line is an essential item for landscapers and this line helps a lot in finishing, cutting, and cleaning up your job easily. You have to buy the right one for your job, not the most demanded trimmer line on the market. So, buy carefully!
