Having a yard or garden outside your home is a wonderful thing, but when weeds rear their heads, your grass can quickly become a source of stress. 

Most people with lawns use lawnmowers to keep the grass at an optimal length.

However, if you have a smaller yard or garden that only needs light maintenance, a lawnmower can feel like a cumbersome tool for the job. 

On the other hand, a weed eater is more lightweight, and it's handy for cutting weeds in areas that are difficult to reach.

To make a weed eater as effective as possible, however, you'll need to invest in some high-quality weed eater string. 

We have personally researched and tested out many weed eater strings and have chosen our top 5 brands.

If you want to get rid of the weeds in your yard quickly, you should buy one of these weed eater strings today! 

Top 5 Weed Eater Strings 

Keep reading to find out which of the top weed eater strings is right for you.

A Anleolife 5-Pound Commercial Square String Trimmer Line

A ANLEOLIFE 5-Pound Commercial Square .095-Inch-by-1280-ft String Trimmer Line in Spool,with Bonus Line Cutter, Orange

Owners of weed eaters have been praising A Anleolife's 5-Pound Commercial Square String Trimmer Line as one of the best weed eater strings on the market and having tried it out ourselves; there's no doubt that this is our top pick!

This multi-sided string makes it more effective at cutting than single-sided weed eater string. 

In addition to being very sharp and good at cutting through even the toughest weeds, the string itself is hardy and durable because it's made from nylon 66 copolymer.

There's nothing worse than your weed eater string snapping suddenly, but you won't have this problem with the A Anleolife string trimmer line! 

You can use this string in all-electric and gas weed eaters, so you don't have to worry about appliance compatibility. 

With that being said, some people find that square weed eater string like this brand is more difficult to wind into the trimmer during installation.

At least cutting the line shouldn't be a problem because the manufacturer has included a helpful, compact cutting tool for this purpose. 


  • Multi-sided cord - Effective cutting 
  • Nylon 66 copolymer - Tough and durable
  • Works for all-electric and gas trimmers - Very compatible
  • Cutting tool included - Makes cutting the line easy
  • 10 spool lengths available - Versatile 


  • Square line is hard to wind - Can be tricky to install

Cyclone Desert Extrusion  Commercial Trimmer Line

Cyclone Desert Extrusion CY065D1/2 .065' x 300' Commercial Trimmer Line Blue (4-Pack)

If our top pick doesn't appeal to you, we recommend the Cyclone Desert Extrusion Commercial Trimmer Line, which most customers report being highly effective and easy to use. 

Made of copolymer material, this is a tough weed eater string product that won't break easily and will last as long as you need it to. 

Additionally, this is a 6-bladed string design, meaning that it cuts through grass and weeds without any difficulty.

The blades are sharp and won't be easily worn down. 

There is 300 feet of string in each pack of this commercial trimmer line, so you won't need to open a new pack for a while.

However, if you want, you can buy this weed eater string in packs of 4 to make it easier to replace when you get to the end of the line. 

Unfortunately, it's difficult to feed this string into your trimmer straight out of the packaging, which can be an issue because taking the entire roll-out of the packaging can cause it to get tangled.

If you need to remove the outer packaging, do so carefully. 


  • 6 blades - Impressive cutting power 
  • Copolymer construction - Extremely durable 
  • 300-foot length - Long-lasting purchase 
  • Available in packs of 4 - Easy to replace 


  • Difficult to feed out of the packaging - Risk of tangling

Oregon 22-855 Heavy-Duty Professional Magnum Gatorline Square String Trimmer Line

Oregon 22-855 Heavy-Duty Professional Magnum Gatorline Square String Trimmer Line .155-Inch Diameter 3-Pound Spool, Gray, 246 ft

The Oregon 22-855 Heavy-Duty Professional Magnum Gatorline might only be third on our list of recommended products, but many customers have reported that they feel like this is the best weed eater string on the market!

We've tested it, and we were very impressed. 

This is a square weed eater string. While we discussed earlier how square string can sometimes be more difficult to feed into trimmers, the benefit is that this type of string cuts cleanly and in straight, even lines.

Additionally, this string is easier to load than a lot of square string brands. In fact, it can be loaded in as little as 30 seconds. 

You can purchase this weed eater string in 4 different lengths, ranging from 25 feet to 413 feet.

However, you should check your weed eater's user manual before buying this string because it's not compatible with every model.

This is something that is important to verify beforehand. 


  • Tough inner core - Resistant to breakage 
  • Square line - Delivers straight and clean cuts 
  • Can be loaded in 30 seconds - User-friendly 
  • 4 lengths available - Can be purchased in 25 to 413 feet 


  • Not compatible with all trimmers - Verification is necessary

Stihl Premium Round Trimmer Line

Stihl Premium Round Trimmer Line .095' / 2.4mm

The Stihl Premium Round Trimmer Line is less costly than the products we've reviewed so far in this guide.

It's sold for a mid-range price, but it's very high quality and will get your lawn or yard weed-free in minutes! 

This is round weed eater string, meaning that it's easy to install compared to square trimmer lines.

Plus, because the string is an eye-catching bright orange color, it's easy to see at all times.

This is important for safety purposes when installing the string, but it also means that you can clearly see how much is left at all times. 

Each pack of Stihl Premium Round Trimmer Line contains 140 feet of string, which is a good amount.

However, in terms of thickness, the string is only 2.4 millimeters, so it's not the best choice for thicker weeds.

For small, more fragile weeds, however, it's perfect. 


  • Round string - Easy to feed 
  • Vivid orange color - Clearly visible during installation
  • 140-foot length - Lasts a long time 


  • 2.4 mm thickness - Not the best for thick weeds

Arnold Maxi-Edge .08-Inch x 140-Foot Commercial Grade Trimmer Line

This string is made with an edge explicitly designed for clean, efficient cutting.

The design is also mostly universal, so whatever weed eater you own, you can count on being able to use this string. 

This weed eater string can be purchased in various lengths and thicknesses.

For example, it's available in lengths ranging from 100 to 280 feet and thicknesses between .08 inches and .155 inches.

This means that you can buy the string in the length and thickness you need for a specific task. 

However, being a budget-friendly option, this isn't the most robust or durable string, so we wouldn't recommend choosing it for highly weed-infested lawns or areas with a lot of thick weeds.

It's best for small, light weeding tasks. 


  • Edged construction - Cuts efficiently 
  • Universal design - Highly compatible 
  • Cutting tool included - Easy to work with

Choosing Weed Eater String for Your Yard 

Best Weed Eater String

Weed eaters are some of the most useful tools for getting rid of pesky weeds around your home, but if you want your weed eater to be as efficient and effective as possible, choosing the perfect string is really important. 

In order to make sure you get the right weed eater string for your needs, here are some things to consider: 


The material used to make weed eater string is significant, especially in terms of flexibility and durability.

Ideally, you don't want the string to be overly stiff because this will make it difficult to work with, but it also needs to be firm enough to cut effectively. 

You also need your string to be able to cut through weeds without breaking, so it's crucial to choose a material that is strong. 

Our top recommendation for weed eater string material is nylon copolymer.

This material is tough, lightweight, and cuts through weeds without difficulty. 


Square weed eater string is often considered to be more effective at cutting than a round weed eater string because it has more edges and can often cut in straighter lines. 

On the other hand, some people who use weed eaters regularly find that square string is difficult to feed into weed eaters and trimmers because you can't allow the string to get twisted. 

Round weed eater string can also be manufactured with edges, so it's definitely possible to find string of this kind that cuts really well.

Plus, it's very easy to feed into the weed eater. 


Weed eater string can be purchased in many lengths.

Weed eater string that comes in greater lengths is usually favorable because it's typically better value for money to get one bigger length of string than smaller lengths in multiple packages. 

With that being said, the length of string you will want to buy will depend on how much string your weed eater can hold at one time and how big an area you want to weed. 


The thickness of your weed eater string is another factor that you should absolutely consider before adding any string to your cart. 

First, you should check the specified string thickness in your weed eater's user manual because some only work with strings of certain thicknesses. 

Secondly, you should consider how dense or thick the weeds in your yard or garden are.

The thicker the weeds, the thicker the string you will need to cut through them.

However, again, you can't use string that is thicker than the manufacturer of your weed eater recommends because doing so could seriously damage your gardening tool. 


We have already spoken about how factors such as construction material can affect the durability of weed eater string.

However, if you have very thick weeds in your yard or on your lawn, you will want to purchase weed eater string that is extra durable. 

One way to ensure that your string definitely won't break while you're weeding your yard is to buy string that is reinforced by a firm inner core.

This will help to make sure that the string doesn't snap, even when confronted with thicker weeds that are more difficult to cut through. 

Additional Features 

Weed eater string doesn't usually come with many additional features, but a useful tool that manufacturers sometimes include is a cutting utensil. 

A cutting tool will allow you to cut the line quickly, safely, and easily when you need to - for example, when you're feeding the string into the trimmer. 

Also, you should consider the color of the string that you buy for your weed eater.

This may seem like a trivial concern, but actually, a bright color can make all the difference to your experience using a weed eater.

For one thing, it just means it's easier to work with while feeding the string into the appliance because you can see the string clearly while winding it around the necessary components of the machine.

Additionally, bright string can easily be monitored in terms of quantity.

It's much easier to tell when your string is running out while you're using your weed eater if the string is brightly colored.  

Frequently Asked Questions 

Why Does My Weed Eater Use So Much String? 

If you have noticed that your weed eater gets through a lot of string, you should consider whether there is an underlying cause rather than purchasing more and more string. 

One of the main reasons why a weed eater might use too much string is that the cap has broken or become worn down through use.

A damaged weed eater cap can cause string to feed out of the trimmer too quickly. 

If you're not sure what's causing your weed eater to go through so much string, you can hire a professional to inspect the appliance for you.

Alternatively, if the weed eater is old, you might want to consider purchasing a new one since wear and tear from age can cause the string feeding mechanism to malfunction. 

Can You Use Any Kind Of Weed Eater String? 

There are several kinds of weed eater string. For example, there are round and square strings.

Therefore, you might be wondering whether you can use any type of string for your weed eater. 

The best thing to do, if you're unsure whether you can use any kind of weed eater string, is to consult the user manual that came with your weed eater.

If you don't have the manual, you can try looking online for product information or contacting the manufacturer for guidance. 

While some weed eater strings are universal, meaning that they can be used in just about any electric or gas-powered trimmer, the reverse isn't always true.

Most weed eaters have upper and lower limits for the thickness and length of string that they can accommodate, which is why it's important to have this information for your specific weed eater before purchasing any string. 

How Can I Stop My Weed Eater String from Getting Tangled?

If your weed eater string gets tangled, this can be a serious problem, not just because it might become unusable (you can't feed knotted string into a weed eater, after all), but if you touch the edges or blades of the string while trying to untangle it, you can cut yourself. 

To stop your weed eater string from getting tangled, the first thing to do is try not to remove it from the packaging while feeding it into the trimmer.

This ensures that it stays coiled inside the packaging. 

Using shorter lengths of trimmer line can also help to prevent tangling because the longer the line, the more likely it is to tie itself in knots. 

Final Thoughts 

Whether you're using an electric or gas-powered weed eater, you will need compatible weed eater string (also known as weed trimmer line) to cut through the unwanted plant matter. 

Hopefully, our guide has helped you find high-quality, affordable weed eater string and answered your questions about these products. 

If you're not sure what kind of weed eater string to buy for your appliance, make sure to consult the user manual or reach out to the manufacturer before you make any purchases.

There are a lot of other factors to consider, too, so remember to assess the density of the weeds you want to remove and how large the area is beforehand. 

Thank you for reading our guide, and good luck with your weeding!
