Finding the Best Trimmer Line

String trimmer line buyers guide.


If you regularly use a string trimmer, you will have already discovered how important it is to get the best line for it. There are several things to consider when buying a spool of string trimmer line. Not all string trimmer line is created equally, and what you end up buying may depend on the string trimmer you own. In this guide, the features to look out for will be covered.

What is the Point of String Trimmer Line?

Odds are, there are areas of your lawn that are hard to mow. This could be due to fencing, a shed, trees, or a patio. This grass will still need to be cut. That is where a string trimmer comes in handy.

” In order for the string trimmer to work, it has to have the right type of line in it for the job at hand.

When you use a string trimmer, the line whips around at incredibly high speeds to cut the grass or weeds. No matter how big your yard is, chances are you need to have some string trimmer line on hand. Buying the right stuff is important.

Line Size

The diameter of the line will determine the size of the material it can handle. There are three different levels of diameter sizes. Light diameters are considered to be between 0.065 inches and 0.08 inches. For medium diameters, the range is 0.085 to 0.105. If you need a heavy duty diameter, you will want to look for 0.11 inches or larger. These larger diameters are considered commercial grade and may be harder to find.

Line Shape

Believe it or not, the shape of your trimmer line can affect how well it works. Most typically you will see square, round, triangular, serrated, and twisted trimmer lines. The shape will help determine what jobs it is appropriate for.

Round: These lines are really only good for small jobs around the house. They are the least durable and powerful of the trimmer line shapes. If you just need to trim grass, this may be the best shape for you. One of the best things about round line is how easy it is to replace in your trimmer head. Round line is usually okay if it hits a sidewalk or stone.

Multi-Sided: This category includes the square, triangle, star, and pentagon shapes. It is good for medium jobs, and is often the perfect choice for homeowners. It will produce cleaner cuts than round line. Heavier weeds can be cut with this type of line. Be aware that this type of line breaks the easiest when it comes it contact with sidewalks, curbs, and large rocks.

Twisted: A twisted line improves the efficiency. It is also much more powerful. Twisted lines are a stronger version of round lines. They produce less noise and vibrations, making for a more comfortable experience. You can also expect clean and even cuts when using a twisted line.

Serrated: If you have a lot of thick weeds, you may need a serrated string trimmer line. They have edges that act like little teeth to cut through the tough stuff. The extra cutting power can make a difficult job more manageable.

Line Length

When shopping for your string trimmer line, you will notice that it often comes in spools. Pay attention to how many feet or yards of line you are getting for your money. Remember, you will not need as much of a heavy-duty line because it will not need to be replaced as often. A large length at a cheap price may be tempting, but you may find you go through it twice as fast as a good quality line.


When the line breaks down, it needs to be replaced. Doing this can be time-consuming as well as hard on your wallet. Reading online reviews is the best way to see how a string trimmer line holds up to different types of challenges. A well-made trimmer line should not have to be replaced often.

Keep in mind the speed you like to use your string trimmer at.

A light-duty line may not be able to handle high speeds.


Trimmer line can come in a few different materials. The material of the line you choose will effect how durable, strong, and expensive it is. The light-duty lines that many homeowners use are generally made of plastic, nylon, or a combination of both. For a more heavy-duty line, you are looking at aluminum, nylon, or synthetic polymers. Usually, more than one material is used to make the heavier lines to add durability as well as strength.


If you are looking for the best line that money can buy, consider buying a titanium line. These lines have a lot to love. They accelerate faster than lines made of other materials. They reduce the amount of fuel you use because they have level flight characteristics. This means no friction and optimum performance. What’s great about titanium versions of string trimmer line is that they fit all standard trimmers.

Trimmer Compatibility/Fit

It is important to check your string trimmer’s owner’s manual for the sizes of line it can take. Many strings are compatible with nearly any trimmer, whether it is gas or electric. Some of the really thick lines may not work with certain trimmers. You will want the line to fit easily into your trimmer head to keep it from sticking.

String trimmers have either a fixed head or a bump feed and twist head. A fixed head will require pre-cut pieces of line. A bump feed and twist head is what will work with a spool.


A heavier duty line is going to cost you more, but it can be a money saver in the end if it lasts longer. A line that is thick and reinforced will need to be replaced far less frequently, which is great for your time and your wallet.


After you buy your line, you will need to give some thought on where you are going to keep it. If you leave it outside in the sun, it can be damaged by the U/V rays. This increases the odds of it breaking on you when you are using it.

It is best to find a cool, dry spot to store your extra trimmer line until you are ready to use it.

Final Thoughts

Having a good string trimmer with the proper line can make your life much easier when it comes to doing yard work. The most important thing to do before shopping for string trimmer line is figure out what the size of the grass or weeds you will be cutting is. Also give some thought to the size of your yard as well as how frequently you will be using your string trimmer.

With a little work, you can discover the perfect string trimmer line for you. When you have found the best line for you, you will find that you get clean and even cuts in half of the time it used to take you. For more information on string trimmers and their components checkout their wiki page.
